I have a 2012 Chevy 2500 Express van that we use to haul our bikes for racing. I have a Kenwood KAC-9105D mono amp (900 watts RMS 1800 watts max) powering two 12 inch Kenwood subs. I am adding another amp (Kenwood KAC-8405 4 Channel 60 watts RMS per channel) to power all the mids and highs. Right now we have a stock alternator and battery and it works fine. We really don't want to add another battery but if i have to i will. Any suggestions?
By the way i do not run the subs or speakers while the van is off.
