Disconnect the speaker wires from speaker terminals on the amp and turn the amp on (turn the head unit on). Set the volume to zero on the head unit.

Does the amp get hot?

If it does, either the bias is set to high or the amp has other problems. If it does not, you may have the speakers wired to the wrong ohm load.

Im looking at this rockford fosgate p700-1bd amp brand new for $300 it comes with a birth sheet it says 750 rms on a 1ohm load. i cant find any reviews about it 225 rms x 1 @ 4-Ohms 450 rms x 1 @ 2-Ohms...


You can't go wrong with Rockford, in my opinion. Everything they make is well built and high quality. I personally have two Rockford p500-1bd amps hooked up to four 12 inch subs in my car and those amps make those subs slam. I have them wired down to 1 ohm and the specs say that they should be pushing 500 rms a piece at 1 ohm so that p700-1bd amp really packs a punch. Depending on what you're hooking up to that amp I would defenitely recommend it to you. - Ryan in Alaska

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)

    Is it enough to power to 12 volge=ahagen 12oowatss dual 4 ohms


    your Volfenhag 12" subs are rated at 1200 watts they are only 600 watts rms and the Rockford punch p4004 is only 200 watts rms so the answer is yes it will work but if you get a amplifier that pushes out 500 - 600 watts rms you will love the sound from subs
    there is nothing wrong with the Rockford amp it just wont pound out the bass as hard but the good news is you will never blow the subs with it
    when buying amps or subs make sure to look at rms rating that is the true power they actually have ie. (sub box says 1200 watt you think powerful but if you divide it in 1/2 you actually get 600 watts rms) don't get me wrong that's a nice rating. for a sub but you will want to match that number with the amps rms rating or lower. The RMS is what makes the car pound the higher the RMS the better
    hope this helps

    Cold weather blown fuse


    You might want to try better quality fuses, or allow the amp to warm up a bit before you start bumping down the street make old ladies angry.
