Rockford Fosgate Punch 225.2, Underrated?

[GaryPham]

Hi guys,

I'm about to pick up one of these oldschool amps locally for a good price and have read that their power ratings are underrated. Does anyone here have first hand experience with these amps and can give me a good estimate of how many watts this amp really puts out? I believe that it's rated at 112.5 X 2 @ 4 ohms, 225 X 2 @ 2 ohms and 450 X 1 @ 4 ohm.

I also have a 2nd question. I'm thinking about purchasing a dvc 4 ohm JL W3 locally and was wondering if it would be possible to use this amp with this sub. I have read somewhere that I could just wire the sub in parallel then run it to only 1 channel (not bridged). This should push 225 RMS to my sub correct? Is there any problem in me wiring it this way?

Thanks again for all your help guys.
