so i have 2 18" fully loaded BTLs waiting to be put in with 2 2400 watt rms hifonics amps....1 amp for each sub...

but i need to know how many batteries do i need ??

also what brand / model ??

also how many amps does the alternator need to be ... i know i need to upgrade the alternator....

what brand ?? where can i get the alternator ??

im not a beginner to car audio so i know a little about what im talking about

this system is going in a 91 honda civic hatch btw

For alternator needs hit up dc powers, it's in the company section of the forums! Also if it were me I would hit up the 270xp they make it's a MFin beast! I'm about to get a dual alt kit from them!

sounds good thanks

DC Power makes great alternators, I have one in my Bronco and I just installed one in my brother's Caliber, we love 'em. I would opt for the biggest one you can afford.

As far as Alternators you go, excessive amperage, Ohio generators, Mean Green, DC power, Mechman, loads of them just have to do a search. Want to get the amperage to supply the power to your 2 amps and the rest of the car's electrical try and find out how much each amp pulls under a load.

I would have posted this in the Electrical section in the main forum. You'll get more responses. As for the alternator I think DC would be a great choice because of their great cs

kk^^

and alright im gonna go with DC Power alternator.... now what about batteries ?? i know i want 1 battery for each amp ... and then 1 battery for my cars electrical.

Do you plan on running the system while idle/car off? if so youre going to need more batts than if you just run the system normally with the car moving. something like a small XS would work fine for up front batt, obv. have your big 3 done, possibly in something large like 2/0. in the back a few deka's/xs power would work great too. bad4health sells dekas for $120 shipped over at ca.com, i run one and it works great.

na i plan to have the car running whenever i run the system...

i dont plan to upgrade the front speakers yet or anything... just the subs and amps for now...thats why i was thinking 1 battery for each amp... then one battery for my cars electrical... so 3 batteries all together...

ive already put my battery in the back so all the batteries are going in the back.. i need to get pics lol... ill get some asap
