Those knobs aren’t volume they are input level adjustments. If you look they have a max of 0db meaning no loss. Some devices have an output level that is to high for the input of the amplifier to handle. The Bluetooth device he had attached was lower output then a professional mixer. The amp was barely working here. Also if you are trying to damage a speaker over powering it is less likely to damage it then under powering as when you under power you are more likely to have distortion and that will destroy your speaker. Also the LED’s that are lighting up are supposed to when signal is present. The more they light up solid without flicker the more signal is present until the LED’s labeled clip start to light up and then you have to much input. This is why I know the output of the Bluetooth device was insufficient. This is not an honest review. This is a guy who has no clue what he is talking about.

I could be mistaken, but I believe that you need something along the lines of a preamp, like a mixer or receiver etc. That way you can use it to boost the signal from the audio source such as cell phone, CD player, cassette deck, etc. that you want to send into the amplifier. Then you can turn up the attenuators on the amplifier to get the desired volume. Thanks for your videos.

If you want to test it correctly then use a non-reactive load which would be either a 4 or an 8 ohm resistor dummy load for an amp like this then run a single sine wave tone through the amp in the range of 500 hz to 1 Khz and use a scope to set the amp for it's highest output BEFORE it clips. Now you have a known voltage is across a known load. You can now do some simple RMS power calculations for the actual power output. Here's a basic formula. P=E^2/R. or better yet in layman's terms, your actual RMS power equals the AC voltage you measured across the dummy load squared then you take the measured squared AC voltage and you divide it into the dummy load's resistive value and this will give you the actual RMS power the amp is outputting. You can also check the frequency response or the "flatness" of the amp by trying different sine wave frequencies in the range of whatever they say this amp is supposed to be able deliver in their spec manual... Hope this helps.

Are you joking?! If you know basic audio and electronics you never compare this amp with the components shown in Video!!

Pretty sure it says don’t run Mids and Highs in Bridge mode 💀

Another thing. If you bridge it then you need an 8 ohm speaker. Check the specs. That car speaker is 4 ohms. The amp is protecting and limiting output. Just run 2 pa speakers to it and retest it

This works like car audio. It needs a pre amp or line driver to match your gains to or you wont get max power out of the amp. Its probably set up to match 2v pre outs and youre giving it .2v pre outs...

This is what happened to me. I was educated by the comments section. I bought a Bellari PA550 pre amp for 130 bucks and it boosted the line signal. With the proper signal getting to the amp it bumps my two Kicker CVX 10s hard enough to cook them. I'm going to repair my Rockford fosgate T2 12 with dual 4 ohm coils and connect it to this amp. One of my tinsel leads broke away from the coil.

First off this is def more of a big boy speakers. It’s protecting your speakers. This is a good amp

Bridged requires 8ohm of load on this device. If the load is too low the amp circuit will be unstable and cook itself. To prevent this the engineer probably implemented something to power limit. Furthermore you are confusing a gain knob with a volume knob, this requires a preamp/receiver

You're not supposed to bridge that amp at 4 ohms. Its not a car amplifier. If you don't have DJ speakers or home audio speakers you should have at least hooked up the 4 ohm speakers on each channel, which is what its rated at. Those speaker wires are tiny too. I am pretty impressed by that little DIY amp you put together. Where did you get the kit from?

Dude...... I was shopping this brand.....and about to place an order.....!!!

Soooo, here is what I noticed. Only clipping I saw was when the speaker wasn't connected, your speaker was covering the clipping lights the whole time...

No disrespect, but I’ve used QSC, Crown, Peavey, and ETC and all have been great amps. However, I own two Rockville power amps the power they put out in amazing. They are clean amps and they thump. You obviously don’t have a clue in how they work.

I notice the wattage adjust to certain speakers, when I tried blowing a smaller speaker, it wouldn't output enough power. When I use my full setup, I'm using two Pioneer CS-705s, and some other 3-way speakers that do 200 watts. I'm also running one channel with JL audio 12 inch sub, does 500 watts RMS, so it's actually peaking the one channel. (I'm also using an equalizer). The total system wattage adds up to 900 watts RMS. I know the amp isn't made to run that, but it handles it just fine from my experience. But I definitely believe you need a signal booster of some sort to unlock its full power, because I had this same issue before without one.

Lol, you must be doing something wrong, mine works great on my 2 12' rockville passive subs

Helps to understand how a pa amp works.

Power amps don't have a volumes unless an integrated amp. I owned a Rockville AMP. They are dependable and decent. You need a pre-AMP to fully appreciate the power of the power AMP. RMS is not the true power of the power amp. You gauge with the wattage. My electronic teacher once said, The bigger the transformer and heavy, that means the amp has enough potential to generate enough power or wattage.

Hook it up right and it will work 😂🤦🏼‍♂️

Rockville should specify input voltage range and not just impedance. Most top brand receiver subwoofer pre outs don’t have a high enough voltage to run this amp correctly.

I have this amp with a numark pre-amp mixer with 2 cerwin vegas dual 15 speakers in my shop… pretty damn loud I’d say.

Could it be your auxiliary input is weak feeding into your amp?

Thanks for the video. I bought it. And yes it disappointed me too. Im definitely returning it back

I have a torque audio amp, but I have a pre amp Rockville, and a 10 band Realistic equalizer too, with a 4 channel mixing board. With this set up I get plenty of highs, mid range and bass. That being said everyone system setup is different.

Por favor su ayuda, Como conecto un altavoz RSG15.4 15" 1500w 4 ohmios y un subwoofer SBG1184 18" 1000w 4 ohmios a este amplificador por favor?

I think you have to use a mixer to try its power!

Excelente

75 dB is like an average quiet car diving. I'd say the fans are loud. But, I don't believe you don't know what you are doing. It's pushing the crap out of that 6X9 no problem. Would you prefer an amp that has no protection and just blows out your speaker? --That little amp has no where near the capabilities of the Rockville, and it clearly doesn't push it hard. Also, if the power out put is limited on the Rockville, and the power difference is even half on that BT amp, you likely wouldn't notice much difference between dB is logarithmic.

Does that say bridged anywhere on the back of that no . The quarter inch says bridged

Correctly operating this amp would go a LONG way towards giving you the promised output... A decent preamp for starters, then maybe a decent cabinet instead of a cheap 6 x 9 in the open air.... This video is like someone reviewing a large condom, with no penis available- then claiming the condom performs poorly....youtube cracks me up sometimes.

This guy is funny. He's gotta do his homework before you start talking bad about a company. He's going in hard, too😂😂

you know they make instruments to actually test the electrical output? Math is math. lets see some draw numbers.

Both volumes have to be up that’s why it’s bridge

Those aren’t rely volumes, more like gains. You set this to how much voltage you are input. I know this is a cheap amp but I’m sure this amp will get a lot louder

Bruh I’m running a ct sounds TROPO d2 and it works awesome the ct sounds flex’s a shit ton with this amp

I have this amp for about 4 years. You will need a preamp or a crossover to get a full output. Very good for small venues. the only problem is overheating, you have to replace the fan/s for a faster one to dissipate the heat, very easy to do still don't expect much for $150.

I just ordered one from The Amazon, and the left side didn't work. I ordered a replacement from the Amazon, and the right side doesn't work. So I have 2 amplifiers running their own speaker because The Amazon is this poor in quality control. Wondering if I can take them apart and put each of the working parts into ONE box and send the broken one back. It's ridiculous !

Could be because the siz or thickness of your speakercables your small cables cant send enough power through your little speaker cables most correctly matched cables are like a 12 to 13 gauge thickness

50-100wpc times 2 is normal for most amps Rockville amp is class AB bluetooth amp is class D which is why it is so small, and it has a higher THD than that rockville amp.

nice seeing the chip set inside that tell the story i suggest a sheerwood 2 ch receiver if one needs a el cheapo unit..i use one and a rack mount peavey amp ..used to have a wharfedale mp1800 monster ....by looking at 80 volt cap 45 watts x2 @ 8 ohms big guess..i my other room i ill use a recapped 1970`s sansui i suggest that or any (Japan unit from 1970`s)) recapped n resisters checked will last 20-30 more years ..never use cheap capacitors nichocon Panasonic etc good stuff only .many of the have preamp out put so the lower powered unit can be bought cheaply strill and are simple to recapp and use then use a big amp but say 45 watts eating from like a sansui or pioneer is loud in it self as it full frequency rated 20hz-20khz at that level ...pardon any bad grammar i just threw up this edited a few times

Clearly doesn't understand how this Amp works.

Or could be some internal resistance blocking the output to keep the amp from blowing I hate electronic questions ha lol!

And I always thought I could trust you man..... And now I see this....

you need a very high input voltage. my denon x3100 barely drives it full output. so 3v in for full output. also, theres a switch in back saying 150hz filter. Mine was defective on one of my two amps. so try it with on and off. this amp is driving my four infinity kappas 10.1 full power and even bottoms out the subs sometimes. please redo this amp test properly. its not garbage. its not a quality amp. but very good for price. and yes it does 400wrms x two.

you need a dj mixer

Hi would you please compare between KFC-710 7”/10” vs pioneer 6”/9” Ts6900pro

if i had used a crossover and a console V:

Can you Power car subwoofers with that amp?

hey Mike Do you have an email i could send you a video of this amp test. i feel bad that this good amp got a bad review. not hating you, just would like to help you out here. i am getting 800wrms out of this amp.

The answer is: For the hit's on my you-tube channel...The question is: Why would you make a video when you know absolutely nothing about amplifiers???

I have to give it to you. The inside have me in a shit ton of questions so I’m not even gonna buy it either

I'm shocked that you do DJ stuff but dont know the difference between a volume control and input sensitivity control. All those knobs are , are level controls to adjust input sensitivity. You need a source that has certain amount of voltage to drive the amp. If you're using a cell phone or something stupid like that, then ya you're not going to get much output. You need a preamp, mixer or some source that can provide whatever voltage is needed to drive the amp to full power. Probably somewhere between 1-3v depending on where the dial is set..etc.

It’s a real review but it’s just a source test my bigg ass qsc 4050 would do the same with line boosters

800 rms or continous, 1600 program or music, 3200 peak. No lies

Yah really tried therr bud feel like this vid a joke lol the amp looks like its sleep preamping it might wake it up

i have 18 in subwoofer is blow up my house man

With all due respect, I suggest you review a product that you are proficient in using. You are posting a video that is misleading, as it will make people that lack actual technical knowledge (like yourself) not purchase an otherwise perfectly fine product. I have that amp (2 units actually) and performed the same test that you did. I even matched the input source type, same speakers and bridged the amp. I got exactly the same result as you! It sounded like garbage. I then put the amp back into the rack ( 8 amps total-4 QSC, 1 Crown, 1 Peavy and 2 Rockvilles) plugged in the XLR input and output, flipped the master power and cranked everything up. I then went down to the bin this Rockville was sending juice to, sat on it and had my balls bounce around for a little bit from the bass the sub and amp were putting out. All I can say is: DUDE, there is/was NOTHING wrong with that amp. Check out ohm's law and check you specs on the stuff you used.

LOLOLOLOL oh god, i haven't laughed that hard in such w long time. you know next to nothing about audio guy. your first mistake is trying to drive that amp with your phone and a 3.5mm trs to rca adapter. you need a line driver or preamp if you want to use your phone as a source, most phones and rechargeable devices have a signal well under a volt and that amp is expecting a couple. secondly that amp is only stable down to 4 ohms stereo, you bridged it at 4, to the amp you just gave it a 2 ohm load on both channels. then you just cranked the gain to 0db. dood, just stop. i have that same exact amp powering 2 2-way speakers with four drivers each at 8 ohms and have no problem getting well over 100db without it even getting hot. yup, the fans are loud, they're loud because the move a lot of air and you're not supposed to be listening with your head a few inches away. it's meant to be operated in a really noisey environment or located some distance away from the audience/crowd. being heavy is actually a good thing because it's a class a/b amp which use MASSIVE toroids meaning that more often then not the heavier the amp is the bigger the toroid, the most expensive part of the amp, and thus the better the performance. rockville might have been overly optimistic about the power handling of their k9's (not to mention how they handled that shit show), but as far as i can see and measure they're spot on here. i'm actually getting about 220w clean per channel @ 1khz with both channels being driven, and it's loud as shit (i can't stand it for more than a few seconds). i mean, if you want to bitch about false power ratings pro audio, right now, is just as bad as the car audio scene in the early 00's. you can, no shit, find a "10kw" amp on amazon for under $200 right this very second. if you just want to pick on rockville then bring up the k9 shit, or maybe make fun of them for their equipment not actually fitting in a 19" rack properly. they seem to screw up more than your average company, but either way, you're the one with egg on his face for being a mindless consumer and not doing your research on how to operate a bleeding amplifier properly before pissing about it on the internet.

Definitely an impedence mismatch going on there. Hook it up to a beefy 4x12 guitar cab or similar and a proper preamp and it will blow the glass out of the windows.

i Think you read the specs wrong...I was going to go into more detail but I think its all been covered.

your signal not clipping the green light is signal and above it the orange or amber is the clip light. i am just saying

There are proper ways to measure output and this isn’t it. This amp is being run naked with no preamp input. The knobs on the front are not volume controls, they are gains. Those amps im learning are actually decent for the money and a real benchmark test would be an interesting show.

Is it compatible with 220volts?

Running a cell phone on that amp won't even clip that amp them dials on amp are gains I've never seen a dj run main amps with a cell phone and expect to get max power from a main amp that cell phone won't even move the gain indicators

Next copy spl from China, inside small trafo and amplifer about 40...50 W

This entire set up is wrong. I run my 1000w amp through my mackie pro10fx. External speakers each at 400w. This pushes it. I think the purchaser bought the wrong type of amp for what use was intended for. I use it to power passive PA speakers. I can guarantee that if you put a mixer in front, it will tear those 6X9 to pieces. I hope you have fixed the issue.

He had both on the positive

You need pre-amp to get power out... This amp is like 200 watts for under $150... Don't test on car's speakers. Need PA speakers...

Learn how to wire a pa amp first and just a reminder before calling it junk hooking up positive and positive speaker wires on both sides is about all I've ever seen🤣 I'd leave it alone bro and do you some 101 on KZfaq on hooking up audio the right way no disrespect but ya signal is way too low for the amp mixer or preamp its not a stereo receiver lol

LOL - you must not know how these work- connect it to speakers that actually need high power levels, that dinky 6x9 obviously caused line accumulation that is activating the protection circuitry... I'm driving folded horns with this amp and about damn near blew out my homes windows with massive clear bass...

You have do do red and black not red and red

Not a real test or the right way to test

I'm gonna second @DJ nighthawk here at no point did i see clipping on the rockville it maybe junk or it could be fine, without a proper test and gain structure you have no clue. First education lesson: the voltage output of a headphone jack or rca device is not enough to drive a pro level amp that is designed to be fed from a mixer or preamp. You need a mixer if you want to run that amp up to clip.

you dont know man

LOL. THIS DUDE DOESN'T READ WHAT FEATURES DOES THE ROCKVILLE RPA SERIES POWER AMPS HAS.

Lol the amp didnt clip

mixer is control that amplifier mixer control bass and treble and volue is call power amp need a fucking mixer

The pocket amplifier sounds better than the big ass one that's embarrassing what a POS

He has both +on each channel that's y he has no sound

If you ran this directly from a cell phone, you should probably take this video down.

your telling the truth i dont think you know how a power amp works tbh using a phone is not a good option, do another review with a proper setup ie a decent mixer and pre amp you ,

U have problems my friend first u need to connect the amplifier with av TV or something else like mixer etc the amplifier will not work properly with what ur connecting all its wrong the main speakers output it's for only monitors nothing more to u can hear what ur putting in outdoors my god

Thank you for this vid, you saved me from buying one of this gb 🤦🏼‍♂️

Hey so...... no shame in not knowing something. It almost seems like you think it's a car amplifier. No criticism or judgement but have you ever looked at the instruction manual ?

You need a pre amp to boost the amp lot louder

lies that amp has alot more power than that

Learn how amps work

Man is right I have 2 18 inch scar subwoofers and I tried it with this same Rockville amp With 2 XLRs And I bridged it And put low frequency on Rockville is a scam, the amp isn’t 3000w, it’s quality you need and not just looking for random pieces of garbage. This is why no one buys Rockville, and it’s not that recognizable Try buying a crown or a QSC. I’m done.

Not a real review!!! You are doing a disservice!!! Get yourself a Analog mixer and two dj speakers. Are you really going to install that amp in your car??

tes sérieux un ampli sono sur des enciente de voiture la mdr

u dont know

I am with you I have the same sh*****

Your getting the white people smile.. GOOD LUCK! :-)

u don't know what u are talking about u need a mixer for the amplifier Rockville 3000 w the amplifier has to be all the way

Based on the size of the components I can assume something about 100W RMS per channel, so I agree it is a crap for the money.

That's wrong dude . Did you not notice that both of those terminals are positive . When you bridge an amp it should be one b+ on one side and the other one should be negative on the other side not positive on both sides

you

Ah blah blah blah... No power... Maybe for a small back yard venue at BEST

Looking inside it’s a cheap amp . It’s not well made and not very powerful

u need mixer for that amplifier
