    A capacitor would not cause an amplifier to blow fuses.

    You have just bandaided the situation instead of fix the problem.

    It will certainly begin to happen again soon.

You have you gain and freq knobs turned up too far, try turning them down and turn down subb level from deck

I have a rockford fosgate punch P325.1 subwoofer mono amp that blows a fuse every time i start the car. I have a second pioneer amp but that works with no problems. How can i fix this?


Is it the correct size fuse ? Is it the power fuse or remote ? Either way check your connections going into the amp . Try this hook your other amp to the set of wires for the rockford if that amp has a problem its a wireing problem if not chances are its an interal problem on the rockford . Hope this helps !

Not a problem just a question


  • 100 watts RMS x 2 at 4 ohms
  • 200 watts RMS x 2 at 2 ohms
  • 400 watts RMS x 1 at 4 ohms in bridged mode
  • stereo or bridged mono output
  • 4-ohm stable in bridged mode
  • Tri-Way capable
  • requires 8-gauge power and ground leads — wiring and hardware not included with amplifier
  • 50-250 Hz high-pass/low-pass (12 dB/octave) crossovers
  • wired remote included for fingertip control of Punch Bass (0-18 dB boost at 45 Hz)
  • MOSFET power supply and output devices
  • MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability
  • TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise
  • Trans•ana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality
  • NOMAD — advanced protection circuitry for "intelligent" shutdown protection
  • speaker- and preamp-level inputs
  • 11-1/8"W x 2-3/8"H x 9-7/8"D


  • Wire your sub in bridged mode (4 ohm mono)
    + to + on amplifier
    - to - on amplifier
    (using bridging terminals)

    The specs I read on the Pioneer site say the amp is not 1 ohm stable, so keep that in mind.

    It partially depends on the impedance of each voice coil on the DVC subs. If they are dual 4 ohm, and you connect the DVCs in parallel ("+"s together, "-"s together), you could run a sub on each channel of the amp(s). This would put about 200W on each sub.

    The other option is to still tie the dual 4 ohm voice coils in parallel, tie 2 subs in series (one "+" to the other "-"), and bridge the two channels of the amp (aka put them in parallel). But this, also, would be about 200W on each sub.

    Things get different if the subs have dual 2 ohm, 3 ohm, or 8 ohm voice coils.

    Rockford amp cut out


    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.

    Amp heats up and goes into protect mode


    Hi Saint108. You're describing it well, and i know what the problem is already. The MA audio amp, can't hold with a 2 ohm load. It's too low for that amp, that's for sure. Those are budget amps and they are not well built enough to handle low ohm setups like that. It's overheating and there's no ways around it.. Other than wiring your subs differently ! Just wire your sub directly (not in parallel) in a 4 ohm load, you will notice it will stop overheating that much. Do it quick, you'll most likely fry your amp giving it such hard work !! The HUM you're hearing could be related to it also. Try that, and keep me posted on the status. Thanks ! Cheebster.

    If the display goes out then it is possible the flex cable is broken. Return it to Rockford for repairs.
