I have 2 banks 1 is for starting battery 2 is two 2 interstate deep cycles a SRM 24 and 27 via a perko, amp is grounded and powered at Srm 24 run in paralel to SRm 27. On bank 1 cd player plays parked no problem, on bank 2 it cuts off and triggers the relay after 1 minute. I have a 4x80 running 4 mb quart 6.5's and a 2 x80 bridged running a mb marine sub with a line driver, power and ground runs are 17 feet with 4 gauge wire. one 6.5 only the tweeter works. Is the woofer blown / do I have a short or voltage issues ? both batteries are new and have charged overnite on a 1.5 amp tricke charge, thanks in advance
