I am currently building my system, I have 4 12inch subs and a saz 2500d. I cant get a H.O Alternator for my car so i was wondering if i can just put in like 4 big batterys. How long would 4 last at moderate volume before the voltage dropped too much. BTW my dad runs a battery buisness so sourcing batterys and chargers is no problem but i want at least a coulple hours worth, Or at least so i can charge them every couple of days is it possible?? I plan to run my 4 channel off my car electrical, So just the Saz 2500d would be on the 4 batterys.
Thanks In Advance
Daniel.
