Great video Mark! I'd also add that fuses can carry 2-3x their rated current for short bursts, so in many cases slightly underfusing is ok. I get the question all the time how an amp with a 100A fuse can pull 150A or more with my Dyno tests. Fact is, it can't for very long! But for short periods it can which is good. As you mentioned, music playback in most cases draws far less current than test tones or music with long bass notes. I also agree it's *BAD* to be on *#TEAMNOFUSE* and there's NO reason to go this route. Use quality components, good wiring and the fuse will never be a bottleneck in your system.
@wb5mgr5 жыл бұрын
Most fuses are specified to survive a certain over current like 50% for a certain certain time delay like 5 seconds sometimes longer in a larger fuse. You have to pull the datasheet to know the time failure curve.

So is the side with the 4 connectors that has the 2 positives and 2 negatives, the same positive and negative for that side? Is it making it easier to connect that side to the other side? Please explain. Thanks

@bbfoto72484 жыл бұрын
@@jefftuttlejr Have you figured this out yet? What exact Brand and Model # subwoofers do you have??? You can use a DMM/Volt-Ohm Meter set to Ohms/Resistance and check for continuity between any two terminals on the subwoofer. For example, if One of the Positive (+) Terminals on the far side that has just the 2 terminals has continuity or "directly connects" to one of the (+) terminals on the side with the 4 connections, you can confirm that they duplicate terminals, but just placed on the other side for wiring convenience. When you check for continuity, if they are connected through the same voice coil, the DMM should display an Ohm rating close to or just under the Nominal Impedance rating of each coil. But this type of terminal arrangement is very unusual. I would think that you actually have "SERVO" subwoofers with a separate SERVO control/feedback circuit??? SERVO subwoofers will have a separate set of terminals for the Servo Feedback Loop which connect to a special amplifier that has a Servo Control Circuit. Look up the specs and user manual for your subwoofers Online for these details!

Mark, To get the proper fuse size in the equation, do we use the amp's max power, or the power I'm using via the ohm rating for my subwoofer? So, I have a 600watt 1-ohm subwoofer connected to a 600watt @ 1ohm class D amp (which the specs say is 2000w max power). Would I just do 600/.8/13.8? Also, my amp has no fuses, so would you recommend using a distribution block? I'm also installing a LOC with a smaller guage power wire than my main power wire 4 awg, so a block should be used, right?

Some old school stuff: fusible links. What are they? Basically a short section [maybe one foot] of purposely undersized wire to guarantee failure point stays under the hood in the event of a hard fault or short. Basic rule of thumb: size down by 4. So, if a distribution wire is 10awg, the fusible link will be 14awg. I like fuses better because failure point stays contained, and replacement is so much easier.

Very good video! I'm already a pretty experienced installer, but every now and then I peruse KZfaq to see what people are doing. Personally I shoot for a wire and fuse that can handle at least 125% of whatever it needs to power. For example, if I have a system that pulls 100amps, I'll wire and fuse it for 125 amps. Also, I prefer circuit breakers because of easy reset as opposed to having to unscrew an ANL fuse in the field. Personal preference though.
@lilflip4162 жыл бұрын
Hey why do you aim for the 125%. Kinda confused because he stepped down to a 120amp. I can kind of see why you would want to go up in amps for the extra headroom and I can understand stepping down is safer. But by stepping down like that doesnt it now have a higher chance of the fuse blowing?

I usually "under" fuse my stuff. Figure out the actual capacities of the wire and all, then de-rate by 20% or so. I do that with just about all my electronics that have user replaceable fuses. I worked as a A/V service tech for many years and learned that a lot of equipment "blows up" but does NOT burn the fuse! The old joke was that the $250.00 picture tube in the TV set will burnout to protect the 30 cent fuse! So, unless you're in a SPL comp event and would rather risk smoking the amp to get that 1st place award, I'd put lower amp fuses in the equipment. If you de-rate the fuse in your amp and it does not pop during power up, you're fine.

@MidnightMarrow3 жыл бұрын
Best way for people to think of fuses would be that it is not only a controlled failure point but being covered etc it's safe. Without the fuse, the wire becomes the fuse and it's far more exposed, which takes longer to burn but as you state can of course be fire hazard. So if the current doesn't kill your gear due to lack of fusing, the fire will and potentially destroy your entire vehicle with risk of hurting you or someone else in the process. In other words, don't skimp on a fuse because you're worried you're losing power to it as the damage that can be caused without them is far worse than the .01 volts you "might" lose.

I want to say congratulations for your channel, I admire you and I like your perfectionism in everything you do! I just have to comment there is a mistake in this video. When you want to calculate the overall current draw of an amp you don't have to deduct the efficiency and this is because if an amp has efficiency for example 80% the rest 20% converts to heat and this energy comes also from the same source which is car's battery. So to finalize if an amp is 1000W that means 1000W / 13.8V = 72.5A (We don't care at this point if 80% of the energy will convert to music and the rest 20% will convert to heat) We just want to calculate the current draw in order to be able to pick up the right fuse. Sorry for my English hope you understand me :)

Glad you like the channel, thanks for watching. Your understanding here is incorrect though. There are plenty of amplifier test videos on KZfaq. Watch and see how much current they pull.

I am really struggling with the fuse size calculation, seems way over kill and too large of a fuse for any electrical application can be like no fuse. If i go off of your calculations of max watts per amp for my 3 amps i need something like 280 amp fuse for my 3 amps, if i go off of RMS watts it is like 135 amps. If that were true how come running maxed out i do not blow a small 40 amp fuse ? if I was drawing anywhere near 100 plus amps my battery would go dead because it is much more than my alternator puts out. None of this is adding up and when i look at the manual for my 1200 watt max amp it says average current draw of 3.1 A, this makes much more sense as to why 3 amps would only be drawing maybe 10 amps top.

Hi Bro, Congratulations 🎊 🎉 ❤️ Brother I'm from Srilanka Can you upload a video about Auto Wire? How we chose a correct wire size for the circuit? Gauges, Ampere lost for the meter etc... All the thinks include in the video. Thank You.

such a very great and informative video! Especially really enjoyed how to determine if amplifier companies are really distributing enough power they claim to their amps by solving for the fuses they should be using! Thank you so much Mark for this awesome and insightful video that was much needed by car audio newcomers like myself!

I watch this video often to reinforce my “expertise”, as my system is always evolving. Just wanted to point out that you cannot put too many fuses… (well technically you could get stupid with them) but better safe than sorry if your not sure. As Mark hilariously and dramatically states here: 14:09 , an inline fuse does not put a bottleneck in your system, but fuses everywhere they’re not really needed can potentially lol.

how many physics class would i have to go for me to learn all that he just taught me. A LOT !!! Thank bro i appreciate the lesson.

Is a busbar ok to use at the rear of my car? I am connecting a kicker keyloc and my 500 watt amp to the busbar and adding a 2amp fuse connected to the busbar then to the keyloc. Do I have to worry about fires using a busbar considering on the side of it is somewhat open?

Are you using the RMS or Max watt rating to calculate the fuse size?

He's using RMS

Thank you for the very informative video. I am in the process of building my system, and am bit confused on the fuse size calculations. The amp I am planning on using for the sub is rated at 150 watts @ 4 ohms, 300 watts @ 2 ohms and 500 watts @ 1 ohm. I will be running the sub @ 2 ohms so the amp will only be producing 300 watts. Should I calculate fuse size based on the 500 watts that the amp is capable of, or the 300 watts that it will actually be producing? Similarly, I plan on utilizing a small 4 channel amp where I will only be using 2 of those channels to power the rear speakers for rear fill. Should I calculate fuse size on the total output of the amplifier (all 4 channels) or just the actual output that will be used ( 2 channels)?

Amazing channel. I assume when you review the 2 amps in this video and quote 1000W for one amp and 400W for the other amp that these are the MAX POWER RATING and NOT the RMS RATING

I love ur videos they been so much help! But what if ur amp dont have a fuse on it?

I have a 8000 watt amp wire at 4000 watts 1ohm for 2 subs, 1500 watt wired at 600 watts for mids, and a 4 channel wired at 100 watts per channel for highs,,,, could you tell me if i figured right at needing a 500 watt main inline fuse. that seems like a lot. learnt just about all on installing from you videos and still learning. thanks

Great video! I bet it sells a lot of wire, fuses and distribution blocks.

can anyone suggest a good quality inline fuse holder and 2-way fused distribution block for use with ring terminals instead of set screws? it seems like almost all of this stuff uses set screws, despite their bad reputation
