I recently put my 1st Gen Rockford Fosgate Punch 45 up against a Polk Audio db8 8" 4-ohm subwoofer in a 0.3ft/3 box and caught the results on video with my Panasonic HDC-TM700 camcorder. This little amp KICKS! See the video for a demonstration (hopefully Youtube doesn't pull the video b/c it has been flagged as copyrighted - short Beastie Boys segment ...)
Vintage Rockford Fosgate Punch 45 in Action!
I plan on putting this little wonder up against an Infinity Perfect 12VQ very soon....
