upgrading the alternators is always one of the best things you can do if its in your budget..

I guess Id goto autozone or someother parts store and look up the alternator for the car your looking at, then it will tell you the size, but sometimes some cars do come with a couple different alternators.

I just used honda as a example, but most the times things like hondas, nissan, geos etc (smaller cars) have smaller alts :(

yea i always figured that smaller cars had smaller alternators

im looking up some prices right now but i have a question about batteries

if i was to connect it like you said positive from batt 1 to batt 2, negative from batt 1 to bat 2, then to amp where would i put a fuse? in between the alt and battery 1 then another between battery 2 then another between the amp? and what size wire and fuse should be used?

and again thanks for the help just wanna make sure i know as much as possible before doing anything

Bass is my drug. One hit and i was hooked.

If your running 2 batteries and you have 1 battery up front and 1 batter in the rear, you should fuse 12-16 inches within the front battery, and then fuse 12-16 inches with in the rear battery. if your amp has internal fuse(s) you have no need to fuse between the rear battery and your amp, but if your amp has no fuse, you should fuse between the rear battery and your amp, fuse size should be the recoomended size fuse for the amp.

If your putting both batteries under the hood, its not really needed to fuse between the 2 batteries, but fuse within 12-16 inches of the 2nd front battery on the wire going to the back.

Now for fusing your front and rear batteries, its best to fuse to the rated amperage that can be carried thru the wire. If your using 1/0 awg wire you should be safe fusing at 300 amps for both the fuses.

Or you can fuse a bit less, say at your alternators max amperage output, or close too it. so if you have a 175 amp alt, you could fuse to 200 amps. If you have a rear battery, most your power will be taken from the rear battery so you wouldnt have as much current running from front to back resulting in a smaller fuse size.

But anywhere from 200-300 amp fuses should be good for 1/0 wire.
