Thanks for the info but not for your comments. I have had Fosgates for the last three years. I know how to research and did my research. All the things you put I already know. MY question was if anyone knew of any problems with this certain amp. I know it is a newer model than the ones I usually deal with. And I know that Fosgate has declined in quality over the years. I wanted feedback, not information. Thanks anyway.
I have a RF 501S AMP and a RF 750S powering 2 subwoofers in the back of my truck. Had them for about 6 months now. And had no problems what so ever. They both pound very hard! I've also never heard of anyone having problems with it. Its a good AMP, so I recommend it to you! Thanks,
