I'm running 2 amps (Forget what output but not massive amounts) 2x 100w/rms soundstreams, 2 x 60w/rms sonys and a 12inch alpine sub. All from a Alpine head (standard 1 slot). My question though is the Caldina battery grunty enough to power all this plus all the other electronics in the car (Lights, wipers, alarm etc)?
Or are people running secondary batteries?
