Car Audio Power Wire - Do's & Dont's for a BETTER SYSTEM!

When you install a custom car audio system you need to add another power wire to connect your battery and alternator to the new aftermarket amplifiers and other new gear. But if you make common mistakes you can loose hundreds of watts of power output... What wire should we use, how large should wire be, and more in this "Car Audio Power Wire - Do's and Don'ts" Video.

I have learned more in the last four months watching your videos than I have in 28 years of loving bass!! Getting ready to fully upgrade my system with a custom box and amp rack. Thank you Mark for being awesome!!

I always recommend wiring with 1/0 gauge OFC even if it's overkill . They'll eventually want to upgrade to more power or a second amp and if they didn't do 1/0 they'd end up paying more to upgrade later on . I always show them my box of old wire . Buy once cry once 😆.

Welding cable makes great power cables. Designed for high current and abrasion resistance, all copper, flexable, and solderable. I solder all my connections and heat shrink/ seal them. Kits are nice from the outside, but I can make some better installations by going ala-carte for my supplies. Don't forget adding a negative cable of the same size from the battery. I see that left out all the time.

The best tip you will ever read is. NEVER USE CCA WIRE. Simple. It may be cheaper. But there is a reason for that

[japguns]

Good vid. I was a professional installer for about 15 years of my life... Every install got better and better. I cannot recommend enough the tips shown here.

[dairyjerry]

Some of my wires for my install were smaller gauge so i compensated by doubling and tripling up the wires and tinning the ends together i checked resistance and works mint also looks cool.

I use welding cable for everything except runs from amps to speakers. Welding cable is pure copper, usually OFC, and made for harsh environments. The manufacturers have to follow strict guidelines for the cable/wire, or it wont even make it to the shelves to be sold, unlike car audio wire. Always go with the biggest wire you can (within reason), due to upgrades that may happen in the future. I'm currently swapping out 1/0 car audio wire for 4/0 welding cable, for my Big 3 and system power. Doing this will future proof things for any upgrades that may happen for me. I should ever have to run new power wire which will save time and money

Luckily, my research actually started with you and your dads NOX! The quality of my install is all because of you man. I think it turned out pretty good. Now I want to drain my wallet at Mobile Solutions so I can build a custom box lol.

[laynewooley]

You should definitely touch on welding cable when it comes to power and grounds. Along with dual inputs/reducers

[lobbyrobby]

I'm putting another aftermarket system in my truck and I've been binge watching your videos. I already had a good idea of most of this stuff but thank you! Lots of good content here and well explained. And yes I was they guy back in the day cranking up my gain making my subs louder 🥴

[cockworx]

Thanks for having the least obnoxious video sponsor segments on the Internet Mark! They're helpful, have an explanation about why you'd use the product, are relevant to your channel and are always nicely segued into...

[LingLing]

Of course this gets uploaded after I just ran my wires 😬 i hope I didn't screw anything up haha

[RJSDZNS]

Just placed an order with Knuconcepts for all my wire, dist. Block and inline fuse. The pricing was incredible for what you get. Thank you Mark!!!

[glenn]

I've always used welding cable, it's super flexible and very durable as welders work in tight spaces and very harsh conditions. Sometimes it's a little cheaper too.

[andrewpelletier]

You have the best videos! Anyone can build whatever system they want with your detailed instructions. Thanks for everything!

[bobriddle]

Knukonceptz is the top of the line for mobil wires, besides i doubt anybody
Else makes the wire they sell, let alone it's a passion for for them.

[davichan]

Just got a KNUCONCEPTS 0 gauge wire set today. Amazing value. It came with one of the most heavy duty fuses I've ever seen lol.
gonna be using it on my American bass 15 inch 2400rms 3800 peak, and my scar 2000d.
Should work rather nicely :) Very nice quality.

[RiddledEnigma]

If I have learned one valuable lesson over the years of installing, that having ya sub amps on a different power wire vs ya mids & highs amps will make a HUGE difference!~

[blackbassuc]

Your information could be a course taught as a class... thank you for making great videos... I could have used them 25years ago... LOL

[geemail]

Any chance you gonne be touching on *"the big three"* upgrades, regarding rewiring your stock alternator and battery?!
