Lol, the ending "bahh---baahhhh-BAHHH"...speaking facts always. I've always had trunk builds and it's always a lot more difficult to get the sound you want as opposed to a truck or SUV. Keep up the great work MBE 👍🏾🤝🏾💯

Back in the day we would put as many 6x9s that we could fit on the rear deck. That was old school

First of all thank you again I just recently found your channel I am a fan of sound so I appreciate someone passing the knowledge on of that I'm the guy in Louisville with the Mustang I took the cardboard out and I'm getting ready to have my upholstery lady cut two holes in each of my back seats about 3 inches by 6 inches and that's all are coming through baby thank you my brother for all of your knowledge

Exactly, very nice having a car that the seats fold down on, creates an excellent port

I have a 2007 Cadillac DTS I removed the rear deck factory sub and left the grill installed and leave the rear seat center pass thru door open and I swear it be getting down even with small powered subs . I did this a while back . Now I know I need to custom out the rear deck to use it as cabin port. Great work big dawg 💪

You’re absolutely right I’ve been installing audio/video since 15 and one way I started off was letting back seat down , and it was a completely different sound . If yo seats don’t fold make a port in the middle of back seat or in deck preferably seat

If it's a quality system you don't have to cut a hole anywhere 🗣💯

Us Texas boys love tearing up the trunk. We go by who has the loudest truck rattle.

Master P had an Impala like that with 6 JL Audio W6 10’s in a bandpass box

Been asking this question for a long time, it's finally been answered. Thank you!

Best thing to do is cut out the rear deck and fabricate a steel frame to reinforce it. That way your trunk can breathe into the main cabin.

Bandpass with the port through the rear deck would sound the best in a trunk

I use to pull my upper back seat loose, so that it was ported. Or cut holes in the rear deck. One car I did away with the deck covering and glued matching cloth back on the deck.

yep, i had a 96 fleetwood brougham back in the day, same exact design as that impala, i cut all that metal off that he showed in the rear of the trunk, and took out all that fabric, and cut a port on the rear deck. made all the difference.

Actually 160+ from my trunk, sealed legal at the dash, @3:31 Thanks for the mention though 😉😎💖✔

I removed my back seats in my Gt86 and put acoustic fabric board over the trunk opening and felt where the seats were than set up 2 sub woofers and 4 tweeters by cutting out holes in the fabric board. Looks great and sounds great plus the sub’s have from facing vents so the airflow is good

I have noticed anything over true 2000 watts rms. It really dont matter if its a trunk or a truck. Rattles are going to happen,thats just what it is. Soo i had the body shop cut the frame from behind the back seat. I then brace the trunk with wood and spray foam,plus thick sound deadener. Made a huge difference.

Personally speaking I love trunk rattle. I live for it. It's not like u won't b able to hear the bass from the cabin. But if u looking to do #s on the meter w a trunk build do a 4th or 6th order with the port goin thru the rear deck or the seats (with modifications ofc) or jus take da back seats out

That was a good rattle impersonation 😂

Got the same body style Impala and I cut a hole where the arm rest folds down to let the bass inside the cabin of the car made a very noticeable difference

All u gon hear iz bop bop bop...🤣🤣🤣 bigg facts tho. A lot of ppl think that just they trunk rattle they doing something..lol

Preach bro, these kids just don’t understand, all they want around here is to rattle trunks and turn heads

Sounds moves thru the use of air plus space...powerful bass notes needs the room to breathe like he says..removing the rear deck, or allowing air space rear in the rear back seat rest is an old school thing I'd do back in the late 80's and 90's..this guy teaching the young generation the game..

Dope advice bruh 💥💯♥️💪👌🔉

Dynamite and spray foam worked for me. No rattle in a 89 town car with 2 JL 13.5 W7, rear deck all ported except for tweeters

I removed my back seat and the deck panel where the 6x9’s mounted and basically made my grand marquis a hatchback/wagon. Since doing that my 9 cubic foot box ported to 24hz breathes great. I sometimes use ports for 30 or so hz tuning but I don’t care about being loud. I also injected foam into my trunk lid and bumper. Long ago my locking mechanism got tore from its mounting so I jb welded it all back together and ran two thick treaded rods to bolt down my trunk I still have a lil bit of rattle. Hair tricks all day with notes ranging from 18hz-28hz. Two Adire Kalis on an 8k 300 amp Alt and two XSpower d7500. About 4500 watts on my mids and highs and plenty of 0 gauge everywhere. I’m not musical but I shake building and other cars no problem

Fire port into cabin and seal off trunk you will gain dbs that way and reduce rattling

It's true you can hear Hella bass in the front, then when you pass no bass and loud trunk rattle. It's the nastiest sound I've ever heard.💯You'd have to be a serious bass head to cut holes in your back seat, I wouldn't do it. I have seen some nice custom work though.

You continue to speak the truth

When I had my 07 Acura tsx I put 2 12’s in it and u use to ride with my back seats down and let them speakers break and it use to sound so good, my mom use to cuss me out because she use to hear me coming from around the corner turn onto her street

Infinite baffle set up with the right drivers and power is epic as well

I've ported through rear deck. Cut seat and have pull down arm rest that vents to trunk or delete back seats completely. I have made custom rear seats that leaves center open as well. Or like my thunderbird SC . WALL IT!

Taking the insulation padding from behind the back seat helps also from them old cars with trunks.

Lmao 🤣 I’ve heard plenty with NO rattle. There is a difference in all cars/trucks and how different individuals deadening their vehicle Just like box building some can and some can’t build

I agree MB👍thanks

Love those impalas!

4th or 6th order ported through the rear deck and completely sealed off

Yes sr 100% correct It’s hard to get the waves in the cab in those cars

Another round of FACT NOT FICTION no I have questions on this good game as always 💯💯💯

Some of the older Accords have a lockable plastic piece that opens up into the trunk. Nice to have

I built custom extensions that I installed onto my rear split fold seats in my bmw M8 .. they are adjustable so when u look back the seats look like their up and closed, but if you look along the top of the seat there’s a port along the entire top of the two back seats latched to the original trunk latches. No cutting required

Miami FL is the home of the Bass!! We used a plywood cut it out 4 12 inch woofers and back in the day we were bumping Black windows peavy band speakers we didn't have no kickers punch none of that and the bass sounds more hard and clear!!!

i got 1 12 in my trunk and sounds great. bass waves prob comming through plastic upper deck on my 2011 accord. Just a little loader if i open up the ski pass through.

The man know something

down here in fla we getting pressure in the cabin and pound the trunk....put a quarter on the roof and see how high you can make it jump

Years ago I had an '02 Dodge Intrepid with a single 12" Kicker L7 on a Cadence 800 watt amp. The box was 3 cu ft net ported at 38hz. Sounded ok, but rattled like hell. I was reading some information on a home audio forum, and they were talking about the space needed between the floor and the bottom of the enclosure for ported downfiring subs. They said that the opening to let all the sound out had to equal the surface area of the subwoofer and the port. So, I knew that just deleting the rear deck speakers wouldn't be enough. I took out the top half of the backseat in my Intrepid. The sub box took up a lot of that open space, but I still had more than equal to the sub and port. I couldn't believe the difference. It was like adding another 12. It just slammed.

I will say though, putting them in the trunk is way better than what I attempted: Took my back seats out of my mustang convertible and put 10 inch subs pointing upward while the motors fit nicely into the seat well. Unfortunately I can't even call it a proper box because I have constant rattles coming from numerous places not being sealed right. I only put them back there because I didnt think I could fit a box in the trunk but now after actually trying....I got them in there still even with proper cubic feet of air space in the new box. Very minimal volume but I am in spec.

Facts...I've been telling ppl this for years.

Am I 85 Chevy Monte Carlo I put towels all around the trunk lid to seal it up more and then give it a little Gap and man there was no trunk rattle it sound beautiful LOL

COLUMBIA SC HERE AND I GOT A CROWN VIC AND I DON'T WANT BEAT IN IT FOR THAT REASON. ILL KEEP MY BOX TUNED TO 27 IN MY 07 DODGE CALIBER INSTEAD. GOOD VIDEO O.G.

When i wanna get crazy ... I drop the back seats 💺 🤪 😎 And it is clear pure bass

Got a Lincoln with 2 15’s and a ported through the rear deck. Shit knocks but I got it done right. Trunk is dynamatted as well so it mostly comes through the deck

Port the rear deck or take the 6x9's out & use those hole's. I killed fools with 4 8's in a 89 taurus cuz I ported the deck.

I put dynamat in the trunk and installed two ten inch free air subs on a board facing the back seat. No trunk rattling and good bass inside the cockpit.

You right when you say Florida. free air ev subwoofer plywood behind the seat they was hurting people back in the 90s with that setup you can hear two mile away

my whole back seat goes down in my 2014 focus so my subs sound good as hell especially with the windows down with one sundown x10v2

That's correct because my Infiniti m45 is hitting and the reason why is that it's the backseat armrest comes down & opens up

Bass stills comes in the cabin even with no holes or seat folded down, yes the holes and seat folded down is louder but you still will get bass in the cabin. And another thing, you can have both seats folded down and your trunk is still gonna rattle.

Man, I was running 2x sealed 12" hx2 on a t1000.1 in my 85 Cutlass and setting off car alarms back in like 2006... had Id known this, that back seat would have been gone lmao

Best way to save money and bang like crazy

He's not lying and I'm actually running DD 9915's and I let my seats down and subs facing cabin

I got a Cadillac XTS my seats fold down it sounds good either up or down

MBE that made sense I'm working on 1 now

Port the rear deck or backseat = into a 4th 04 6th order !! Use 3 or 4" ports and adjust to your preferences 💪😎🙏

Anybody that drives G bodies and B bodies should already know that, all about the gorillas in the trunk 😎💪

This is perfect explanation for school bass💯. Been fw audio since 16 and now 5 years later I been through every sub BUT 4 15’s (I got 2 15’ now) 2 different cars I built out and the 2 15’s is perfect cause it’s so fuckin loud from the outside that’s what I wont😂😂😂 but 1 15’ tuned for lows is nice ig

I’ve effectively turned my trunk from just a box with subs into a 6th order.

FACTS!

i think the best way to do it is to cut the rear deck and have the woofers fire off the glass

MBE FTW 💪🏾

One hell of a gem to drop. 🫡🔊🔊🔊

350lbs of sound deading, no rattles. If I want sp I just fold down the seat but I do more sq. Yes it's a ported box in a sealed box, a 3rd order bandpass. As good as a hatch? No but moving my hair with sp, yes.

He not lying it’s hard to fr 😢

i think a blow through box is good for the trunk too!

Great advice I’m needing some pointers on my build I have a 63 impala I’m currently running 2 10” Alpine Type Rs and a skar1200 @ 1 ohm it’s not hitting how I would like for it to I’m using a prefab box ported any suggestions on what I should do to get better sound

i always get th sawzaw out lol but i have 3 wolfram 12s 2000 rms a piece on a 12k in a 03 buick lasaber my friend has 3 15s re audio on a toro 6k in a wall in a honda accord we went to a db show we both hit the same number on the meter but ya next build going to be a hatch or a truck

This is a black man with muscles I think he knows what he is talking about

What about for a 84 z28 camaro. The trunk area is open to the cabin but the space for the box isn’t that large. What’s a good set up for a 3rd Gen camaro?

Some people port the rear deck

02 lexus ls430 has opening in the back seat. So having a ported box in the truck with the opening in the back seat helps. And d9es that technically make it a 4th or 6th order box now?

Damn. I'm screwed then. I have a 94 Impala SS. Low miles. I don't want to do anything where I have to cut into the back seat or rear deck to severely reduce trunk rattle. I want subs in the trunk and minimal trunk rattle. If I would have to cut into the back seat or rear deck in order to achieve this, I will opt with no subs. DAMN IT!

I have an 8 inch hole there that was the stock sub that i pulled out.

Shout out to that Green Regal in Atlanta back in the day!!! Big shout out to G-Bodys!

Cut out back deck foam the trunk lid & dynamat take the trunk rods off to make it heavy trust me it works

Folded seats help alot when them seats drop it can get ugly

I have a Lexus and put a system in it removed the sub from the rear deck redone the rear deck made it stronger and my port with a grill is there and my subs make a hell of a lot of pressure inside the car people he speaks truth

Luckily a lot of the 2000 vehicles. The rear seats fold down. But I do understand that rattle. And it is annoying as hell to hear it from the outside.🤣😂🤣

🔥🔥🔥🔥

MBE we also vent the rear deck

Wow that’s great stuff 🫡

what if I fold my seats down and face my box towards the cabin? what would this do

Yeah, those old school cars that's probably the best solution.... but newer cars not so much... first off, the bass is going to get in the car. If you are running a DSP and it's tuned right with proper time alignment for your subs, the bass will sound alot better and play right in the listening position in the car.... the only way I would port my rear deck or backseat is for a bandpass setup.... and porting the rear deck does nothing in terms of gaining output.

well i got a 71 LTD convertible, there's a lotta ways that bass can get out 😁

Real players remove the back seat.

Funny you are showing SS Impala....those would kill the bass when you close the trunk if it's smaller box....the trunk just cancels much of bass...now with a big ported box say 4x12s that would change acoustics of that trunk and sounded as good a woofers in trunk could sound ...when those cars were new we did 4x10 in 4th order bandpass vented thru deck...that worked really well...

I really enjoy your channel , but being hearing impaired I'll be stoked when your Audio improves 💪😎🙏

I just drop the seat😂 but I have a 21 Elantra

💯

I have done too many trunk installs at the end of the day trust me just get a hatchback. Takes a lot of fabrication to make a trunk system right. Hatchback is king!

💪🏾💯
