Tried the 2 battery thing, worked for awhile, then it was the same thing. 2 batteries will help as long as you drive around for awhile with your stereo off to charge both batteries, then turn your stereo on. Your altenator is still putting out the same amount of amps, but now it's only sending half to each battery.
If you do this make sure you go with a good brand. I also did this in my Topaz and it drew current either way, so if I unhooked the battery in the front, the car would still turnover becuase of the battery in the back.
And even if you do both, while your systems not on full blast you still run the risk of frying something.
Caps come in different sizes depending on your needs.
1 farad is equal to 1000 watts. they have .5,1,1.5,2 and probably higher, Are you really going to be running more than 2000 watts through your system?
Caps are made just for the purpose of storing energy for your stereo system.
This is my .02 from my past experiences.
If you are looking for something like that high powered altenator try JCWhitney's, they usually carry items like that, thats where I bought the kit for the second battery.


Yeah I will really be running 2000 watts. Closer to 3000 actually. Caps really would not help that much. They disscharge so fast that after a huge bass hit they become useless, if not even a drain. (unless I wanted to go in to the 5+ farad sizes)

Has anyone changed their alt before? Is it hard to do on this car?

thanks for the replys guys
