Re: Need replacement Amp
If you have 2 Dual 8 ohm subs you could run these at 2 ohms with the coils in parallel and the subs in parallel. Since the KAC-7204 is a 2-channel amp I think you had the subs wired to 4 ohms with one sub going to each channel. A mono 2 ohm amp could do you well and you'd gain a remote bass knob. We have a special now on the Precision Power i650.1 for $119.99 shipped. This uses the latest Class D small footprint design to make 650W at 2 ohms with an amp that's only 9" long by 5" wide. This amp would save you a lot of money and get you a bump up in power.
