4 l7s and a 2500.1 what upgrades pls

hey first off let me say thanks for reading my post i have a 1989 Chevy Caprice... anyways, i have 4 12" Kicker L7s and a Kicker zx2500.1 with a Kicker zx350.4 for my components that i have yet to get... my question is tho what upgrades do i need to do to my car.. i have heard a couple different things, i was told i need two yellow tops, one under the hood and one in the trunk with an alternator upgrade... then i heard my car battery with a kinetic in the trunk with new alternator upgrade... i want to do it right and i would my Caprice to POUND but i am on a budget so i would like to do this inexpensively as possible i also heard talk about battery isolators, is that worth getting, i look into them.. the idea behind them is great but to they work, thank you so much plese help me out with any suggestions possible - Jordan

yellow tops are decent...There are plenty of different battery manufacturers that make sealed batteries. First thing to do upgrade your alternator to a high output alternator. The biggest you can afford...the bigger the better. Then upgrade your big three and all possible ground straps and wires on the vehicle. To it seems like you have the money to upgrade your electrical since you have four L7s, a 2500.1, and a 350.4 Forget about the isolators...get the biggest kinetik you can fit under the hood and a 2400 in the rear.

thanks so much, i have heard about this "big three" and just started reading about about it a little, doesn't seem to hard to do, although i am not sure where to get a high output alternator... do i have to have this custom made or what?

u can put kinetiks under the hood as ur main car battery?

Kinetik and powermaster are both great betteries, I would replace both batteries you plan to do with the largest you could. Go with the biggest alternator you can afford. Look for reputable alternator companies like powermaster, Irrigi alternator, H.O altertnator.2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

hey thanks for everyones help and input would a 140amp alternator with the big three upgrade be sufficient??.... ...or do i NEED to get one of the high output ones and if so where would i get a high output one i called Murrays Auto and they said they didnt have high output ones... should i just shop online?

hey i forgot to mention does it matter that my car DOES NOT have power windows, locks or seats... i heard somethin along those lines before i really dont know tho

get an irrigi of ebay. best prices i have found, for my car at least. for a HO alternator.two 12" cadence TXW-12S, cadence TXA-3002 amplifier, 1990 toyota celica system 10 speakers
