suggestions on voltage drops?

[Bagged96Chevy 10+ year member]

my current setup is 2 12" l5 kickers powered by a 1200.1 Kicker amp and i was wondering what you guys recommend for wire size going from bat to amp i have 1/0 on there now and wondering if i'm losing power its about a 15ft run

(i have done the big 3 and i still have pretty large voltage drops)

and to my knowledge the stock alt is 100/105

more lines you run to the back the less your volts go down

how many lines would you recommend for the setup listed above?

I would do 2 0-gauge runs...I like going with 4 though...go with as many as you can manage without things getting out of hand. Also, remember to put fuses at each end of each run if you have a battery/batteries in the rear...

so 2 grounds and 2 hots is what i should start with? could i use smaller on the grounds or would that be hurting me?

What are your voltage drops?

 

[Bagged96Chevy 10+ year member]

goes from from around 13 to 10 it ******* the power clean out of the headunit i think

Well, you have a problem that it is dropping that low. You also have a problem that it sits that low to begin with. Mine sits between 14.2 and 13.8, and drops to 12.3 minimum for burps.

If your initial voltage is that low, your issue may be charging your current battery, which would mean you need a new alternator. So you have a couple of options (2nd battery, alternator, both), but I would go with a second battery first because it should be cheapest.

A second batt would just be a bandaide.
