So currently I run a hartke hydrive 410 with SM500, and I am wanting to switch to a separate pre/power set up. Im leaning towards a DB659 and Crown XLS1500. My question is, to run the amp in bridge mono, do I need to rewire the cable going into the amp AND the cabinet? do I need to rewire the connections in the cab? I know nothing about wiring, any info would be greatly appreciated.
