Help, bought an amp on line. It was a 1200 watt at 1 ohm audiobahn amp. I got a a1500hcx amp in the mail. This amp is worth more but I don't know if I can use it. It has the wiring options in the booklet and everything is a dual 6 ohm settup. I already have a pair of a1000q audiobahn subs that are dual 4 ohm. I was all ready to run the two subs together mono and go. What can I do?
