high amp alternator on an 89-95

Hey everyone, its me again here to bitch. I just bought a high amp alternator for my truck to help power my system and it is suppost to be a 160 amp alternator but it is only getting 121 amps to my battery. My question is, for those of you who have done similar, how much amperage can the stock wire flow for the alternator? On some of the alternators I have seen they call for a 4 awg power wire to be ran to correctly supply the power they produce. Is this true? While I am at it, does anybody know where I can get at least a 180 amp alternator to go in the stock location and plug in? I bought my alternator from ace alternators, they advertise on ebay so you all know. And I would like to put an additional alternator where my a/c compressor is suppost to be, how do I go about mounting it? If you all are wondering I need 400 total amps to correctly power my system and my truck at the same time. 9 12's, 2 8's, 2 6x9's, 2 6.5's, 2 4's, and 8 tweets. coming in at a total of 4000 watts worth of amps, not cheap amps either, kicker and kenwood excelon. and yes I have additional batteries, 2 hc2400 kinetik's.

you need to find out where it puts out 160 amps. most of these high output alternators are advertized a srtain amperage but it will be at 8,000 rpm or something crazy.

have you dont the big three upgrade? upgrade from alt to battery. battery to block. and block to frame. i am running 4g wire and it made a huge difference.

I bought a 160 alt from ace alternators on ebay and i did the big three upgrade and i have 4 480 compressors, 1 12" sub, 1000 watt amp and my truck runs fine, the upgrade makes allt he difference man=bigger wires more flow of power distributed out heres the link for instructions on the upgrade:

ditto. i run 0 gauge ground straps from the battery to the block. then i usually let the stock ground strap go to the body from the engine. and a nice big body to battery ground. it helps let things flow well. and a bigger lead from the alternator is a good idea too.

thats not what ive done on yotas, thats on dodges but its the same principal.

Mine has a T100 alternator on it, the pulley had to be shimmed out to align with the crank.

amperage is typically measured at a higher than idle rpm

they said 70 amps at 700rpm and full 160 at 1200. I will have to do the big three then get it re-checked to see what it is getting to my battery. I thought it would be a difference but not that big of a difference. so will I be better off with 4awg or 0/1 awg? I am running 1/0 awg kicker for all of my stereo so I am guessing 1/0awg on the alternator as well but that seems a bit overkill to me at least.

I have a 4000 watt amp in my buick. I upgraded the stock 100 amp alternator to a 300 amp alternator. I didn't really notice the difference. The lights dimmed either way. Even with huge quality wiring.

I'm not really sold on high output alternators. If I had it to do again I would run dual stock 100 amp alternators instead of a high output 200 or 300 amp one. Cheaper, too.

definately upgrade the big 3 to 0ga wire... I ran all new wiring from my alt to a fuse then one to starter and one to battery... and make a nice ground wire from the battery directly to the frame... it all will help you out alot
