Lights dimming

[motox_727 10+ year member]

Well i have a chevy s10 ext and im not really sure how many volts the alt is but I am having a lot of trouble with my lights dimming. My amp is a Kicker ZX1000.1. We have a 12v battery up front and a second battery in the back.. My buddy has told me about 15v batteries, would this stop the problem? when I am driving I dont have any problems but once i stop at a red light with the heater on it will sometimes kill the motor and it dims the lights really bad.. My dad keeps getting pissed off because he already has over 1500 in my system and we keep running into more problems, any ideas?

Sounds like you need the big 3 done...and maybe a beefier alternator

does ur s10 make any wierd sounds when runnin the car.new alt is prob way to go.

nah the alt used to whine but doesnt anymore.. now once i turn up the subs to a certain volume, the amp turns off them on, not getting enough juice or is my speaker wire not heavy enough? because my dad said either of those could be factors

you need a bigger alt, and u seriously need to do a big 3....

What gauge speaker wire are you running? you need, at LEAST, a good 4awg to that kicker

2awg might be overkill but it'd do it **** well

so 4 gauge to the amp? and how big for speaker wire?

also after I do the "big 3" will that totally resolve my problem or should i still get another battery and a capacitor? Sometimes it sucks so much power the amp just shuts off (-.-)
