Rockford Fosgate Punch 45HD - Old School Cheater Amp!

The Rockford Fosgate Punch 45HD was one of the original "cheater amps". This amp was the king of the 0-50 watt competition class in the early 90's. Other notable contenders were the Orion 225HCCA and PPI ProMos 25 (which cost nearly 2x as much). The Punch 45HD originally retailed for $279 US and was rather difficult to find in stock. Many competitors used complex passive crossover networks and several speakers (10-12 or more) all powered by the Punch 45HD. By using the "tri-mode" operation, you could bridge the channels for subwoofers while retaining stereo operation for the mids and highs.

My Punch 45HD "birth sheet" stated 91 watts/ch into 2ohm loads. I can't remember if they stated 4ohm loads back then, but it should be around 50w/ch. My birth sheet is MIA (along with the original manual), but I'm sure I'll come across it someday.

Keep tuned in for a future test comparing the 1st Gen Punch 45, Punch 45HD and the "25 to Life" Punch 45....three awesome amps ranging from the late 1980's up to 2005.
