If you think that will get loud at 800 watts... well, lets just say you have virgin ears. That thing on 125 watts, or even 800 watts would get owned by two audiobahn 6.5"'s in a powered4sound enclosure.
Ive done nothing yet, im not sure if its over 140rms or not because the guy who i got the amp from said it was an un-reggulated amp. Whatever that means...
