Using rear battery for outboard amps
I have a 2012 E63 which has a rear battery for the Airmatic & start/stop system (which I always disable).
Want to hook up a couple of high-current amps with a total current draw of approx 130-150A. To my knowledge the OE alternator is 180A. May be a stupid question, but will the rear battery which is AGM and 200 CCA be ok for this? I have no intention of running the amps with the engine off/battery only.
