Rockstar - What sub is this driving? This is a lot of amplifier for most subwoofer(s) on the market. Yes sure we make a 2500.1 as well, but it's rarely needed for service as the 1500.1 is pretty stout!
Shoot me an email and lets go over your system configuration and go from there. If your subwoofer can handle the increased power I'll steer you in the right direction.
