AH rating doesn't make a damn in car audio. Just get XS Power and be done with it.

Think about it.....faster discharge = more "instantaneous" power (like a cap). AH the bigger the better, meaning you can play longer without the vehicle on.

How long does it take to go from 14 volts to 11 with the vehicle off?

1 16k and it drains ya in 20 secs from 14-11? I would say yer batts are shot. You are only pulling like 1150 amps at most. There is definitely something wrong there.
