Just got some good news!
my current upgrades:
50+ft of 1/0 or 2/0
three bats
110A Mitsubishi alt
and just yesterday- i pulled the stock alt out of the front location and installed an alt off a 2002 Explorer sport so 110A +130A = 240A max @2000rpm GRIN GRIN GRIN
after doing some test drives with the DMM watching the kinetic battery closest to the amp- saw 14.7 with the system off and 14.3 with the system cranked! that is almost 1v higher than i've ever had it, and this is with ~3200w of bass power
not bad considering the stock 70A alt never got above 13.8v without anything hooked up, and at one point had 12.00v with the car running and sytem off.

Drew,
That sounds like a big step in the right direction to feed your massive Bass Engine. The higher the net voltage, the lower the net current drain.
If I understand this correctly, you now have dual ALT's and 3 batteries to feed power to the system yes?
Are they separated so that one ALT power 2 BAT's for the sub amp and the other powers the main BAT and other vehicle needs?
Say more so we can all learn something new!

I've found its best to have a joined system when running 12v
i only suggest running a separate systems if your bass engine is running 16v batteries
so i have
Bat 1
Bat 2
Bat 3
Alt 1
Alt 2
numbers go lowest to highest starting in the front of the car moving back.
Under the hood- Alt 1 to Bat 1 that also powers the car
bat 1 is paralleled to bat 2 that is being fed by alt 2
bat 2 has one run + and one run - running to the bat 3 (behind the drivers seat) then continues to the amp. everything with a ground is grounded to the main ground wire, and the frame.

I never got into the mutliple alt/battery systems. How many fuses and where are they located?
newB on 02/24/2009 22:03:27
one on every long wire leaving the bat- so between each bat and alt and between bat 2 and 3, one on each side.
if you ground out the power wire at any spot, you want a fuse to pop not a battery. short runs (bat 3 to amp and bat 1 to bat 2) don't need to be fused as long as they are ran safely
