i'll think about it, but i think that i can get one new for that much in my town, i got a hook up at ABC. It sounds like it will work though . Let me check on the price i can get from there first.
I have a Rockford Fosgate Power 450s - with ALL original documentation and original box - $150
I am not sure what you mean by "true 500w rms" but the birth sheet on this says 479w and an efficency of 67.730. If you ask me that really good. If you want I can scan if for proof or something if you are interested. Like new condition, pretty much like Mikeyspice's amp.
You can look at my classified ad on this forum for more details:
