I installed them on my 88 gt and had stalling problems. It wouldn't keep a charge. Whenever i was idling i had to keep giving it gas to keep my battery charged. I bought a new battery and the problem was fixed. If your battery is old, that could be your problem. If you have an aftermarket stereo system that is drawing a lot of power, that will worsen any charging problem. If nothing else works you'll have to buy a bigger alternator (not expensive)

mine is crappy as hell at idle once i start cruising it's okay but i don't have the heater in it yet or a radio. i'm thinking about installing dual batter set up

A larger amp alternator will cure what ailes you. Unless you're going to be running a monster stereo, you don't need 2 batteries or 2 alt.'s.

well i'm runing a electric fuel pump dual fans, and when ever i get the insides done i'm runing a jl w0 12 in a bandpass box and all aftermarket speakers i run dual jls in the camaro and when it hits real hard the voltmeter drops from 16 to like 12 i put a capsitor on it and it dosn't drop as bad.

dual batts wont help if you cant charge them.if your running a stereo scrap the underdrives.I run 2 alts and 3 batts my voltage never goes below 15.0v

i'm not running 6000 watts though that's insane 150 db that much could kill ya lol

^^^ I want a setup like that soooo bad.... Just not in the Stang

i really want to take the system out of this car because stangs are hard to get loud.My set up would be alot louder in a diff car.If you all a looking for a good alt try ohio generators or stinger electronics they got some nice 200 amp alts. stinger alts come powder coated and the ohio looks stock but has better performance than the stinger

^^expect to pay atleast $500 for these alts but you get what you pay for
