97 Accord... and Saz-1500@1

[jdawg90 10+ year member]

What would it take to keep my voltage in the say 13's? The car has a 90 amp alternator (i think) and some ****** battery up front. I'm going to do the big 3 and use 1/0 for everything.

I'd like to do something like keeping the one up front and run an isolator (or something similiar) to keep it separate from the battery(ies) in the trunk. I know absolutely nothing about isolators. And yea, i won't be burping but do like to bump... none of that non stop 40hz **** though.

Is a run of 1/0 for the ground to the battery up front worth it? I've got about 25ft of hyperflex on hand. I'm kinda concerned bc my old truck was hitting low 12's on some songs with a zx1500@2 and a 130a alt with a g34 intimidator up front...

Do big 3 and switch your front battery with something more suited to car audio and see what you get... Its very possible this might suffice, however if you want high 13's while your at full tilt w/ air con w/ head lights...etc...new alt

I run an M3a in my 98 accord without big 3 and a single big Deka in the truck at about half tilt no problem... I dont run an isolator either and have never had a problem with drain... I am probably selling my batts as well if youd be interested let me know...
