[m.doza]

hey guys just wanted to make sure i have enough electrical to back this setup. all amps are soundstream 2500d(1),500.4(1) and 600.2(1). i have a 170amp alt and (3)group 24 batteries 74ah. thanks for the help

so you have 170+220=390ah.

I'd say yes, but I would recommend another battery

ok I did the math at 13V. So you'll need 340AH remaining, and you have 390 but also take into consideration what your car is using, so subtract around 40ah

youre left with 10AH over, so you should be good. Have a run of atleast one negative and one positive 1/0 to the rear batteries and you should be good to go!

I think you are fine, you wont be using full power all the time anyways.

and they are soundstream so you probably wont get rated out of them aynways.
