Point is, your delivery offers something for both the novice and the expert, and you’re producing the most compelling car audio content on the web by far. Strong work, thank you. God Bless, Jay

[@wal]

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.

[@wb5mgr]

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.

This comment is for all of your videos all together. I started watching your channel video's 2 months ago and I learnt so much from you and I purchased everything online from amazon and so. And installed it all by myself and I'm so happy how it turned out. I'm so glad I found your channel and you're amazing. Thanks for all the video and you helped me save couple hunder bucks and a awesome built (if I go to a car audio place and tell them to do what I did, they'll just say oh no it's not necessary, you don't need fast rings, you don't need 4 gauge wire, 10 gauge is enough to power 2 amplifiers, you don't need spacers, we can screw our speakers on bare metal, you don't need to scratch paint for body earth) not every professional place does this but I see so many places do this and I'm so glad I did my car audio all by myself and it sounds so good. Lots of love from India 🇮🇳 ❤️ stay safe and make more videos about car audio improvement

[@jefftuttlejr]

CarAudioFabrication hello, I have a question. I have new 12” subs with 4 connectors on one coil and 2 on the other coil. How is this easier to run series or parallel? 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

[@GahhDamnAlex]

It better to run 2 subs that have the same voil coil configuration. It looks like you have 1 dual voice coil and one single voice coil sub.

[@bbfoto7248]

@@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!

It’s not like car people have a code for them like electricians do. We have NFPA 70, 70A and 70E. Your calculations are correct based on your math and I see you are correct in being on the safe side in your choice of fuses. Burning up your investment is never a good thing.

[@miket5506]

Very good video! I'm already a pretty experienced installer, but every now and then I peruse KZbin 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.

[@lilflip416]

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 like knukoncptz products but make sure to check the screws in the distribution blocks every once in a while or add lock washers.

Was installed for about 7 months then one day started smelling something burn, thought it was the subs but they were cold. Then found the fuse block plastic melted

[@bbfoto7248]

@john d This is common due to the many hot/cold cycles of your vehicle on a daily basis, and all of the engine and road vibration, etc. Use a bit of the *LocTite Threadlocker Blue 242* adhesive on your terminal block's set screw threads.

I generally just fuse to a little under what the max amperage of what the wire itself can handle. I try to stick to one amp for the whole system though to make it easier. Just use the recommended wire size from the manufacturer on a 5 or 6 channel amp. Good info as always.

[@asurf08]

hi caraudiofabrication, look at the minute 10.06, why the power (1400 watt) of the amplifier must divide by the 80% efficiency. it supposed the value watt to be more less if the working efficiency is 80%. if im not mistaken, 1400 watt must multiply with 80% and the result is 1120. i'm enjoy your video. keep up the good work. thanks...

[@CarAudioFabrication]

Nope. Wrong. I'm calculating how much power IN is needed. You must have MORE power in than out. The math in the video is correct

[@asurf08]

Thanks, for your explanation...will be apply on my car audio system upgrade...

[@switzerland3696]

Old bugger here, back in my day once I started doing large systems for competition, we did not use fuses, this was before lithium batteries, so just lead acid batteries. We would use 95mm^2 cables, so less of a fire risk than using any sort of normally sizes cable.

[@ioannischerouveim7239]

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 :)

[@CarAudioFabrication]

Glad you like the channel, thanks for watching. Your understanding here is incorrect though. There are plenty of amplifier test videos on KZbin. Watch and see how much current they pull. The amps must pull more current to create the rated power because of losses in efficiency. You must take a rough efficiency value into account.

fuse and fuse holder resistance.... Excellent point.

[@flinch622]

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.

[@TrippySkippy8]

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?

[@theejoeylee]

Also keep the fused dist. block close to the amp as possible. this keeps the reduced size wire short as possible, which will be able to carry more current than a longer run. Actually, just a good idea to keep all cables short as possible. Don't leave 5 ft of extra wire just balled up in the trunk. Looks bad too.
