I have a Rockford Fosgate T500.1bd for trade, you can see it also for sale in the amplifier classifieds. It's got less than 12 hours of use on it and is only 11 days old installed for just 4 days! I upgraded my power and no longer need this amp but the store I got it from won't accpect returns. I'm looking for a 12" subwoofer that runs at 1000 - 1500watts rms, DVC, 4ohm. I want to run it in parallel with my American bass VFL Exterme DVC 4ohm subwoofer so there wired down to 1ohm. I'm looking for preferably an American bass XFL or VFL Exterme but im not sure if anyone has any. But hit me up let me know!!
