Question about Rockford Fosgate Punch P2002 Car Audio Amplifier
An amp was previously installed in this vehicle
This amplifier is a 2 channel 50watts rms per channel and would not really be powerful enough to drive a subwoofer of any substance for car use, however , bridging it would give you 200watt rms into 4 OHMS but your subwoofer would have to be a single 4 OHM voice coil. Best you use this amplifier to drive a pair of speakers.
Hope this helps. let me know if I can further assist you

Disconnect all speaker wires from the speaker terminals of the amp and disconnect the RCAs. Replace the 30 amp fuse with a 15 amp fuse. If you turn it on and it blows the fuse, it's likely that it has shorted output transistors. If that's the case, you need to have the amp repaired.

If the woofer isn't moving significantly, try the following settings:
gain at highest (most sensitive) setting
crossover at highest frequency
subsonic filter at the lowest frequency
If those do nothing and you have a dual voice coil woofer, you may have one coil reversed. If you disconnect one voice coil and the woofer moves significantly more, check the polarity of all speaker wire connections.
Here's a brochure for the amp:
You're correct. this amp cannot be bridged to produce more power. It's minimum safe load is 4 ohms per channel. It's essentially two bridged amps in one chassis.
