Rockford Fosgate Punch 360.2

Using the amp bridged to a 4 ohm load. The speaker wires touched + to - and the amp began to play inconsistently then quit playing altogether. The amp also became unusually hot. Now the amp does not play but does turn on.

Re: Rockford Fosgate Punch 360.2

If the wires were touching then the amp overworked itself into a early grave..What happends when they touch is the amp goes from seeing a 4 ohm load to seeing a 0 ohm load. You can imagine why this would be bad for a amp...usually the amp should shut off to protect from damage and I would assume that Rockford would. Right now im having a similar problem..I suggest your call rockford and ask to talk to a technical advisor ( the name escapes me) and ask him what he thinks.

I have a rockford fosgate t1500 amplifier and two 12"kicker L5's duel voice coil. the subs are wired together as one. they worked for about half an hour. now the amp and head unit comes on but no...

This amp is rated at 200 watts when run at 4 ohm load when in bridged mode (mono).You will need to check the measurement of the load at the amp's positive and negative location where it meets the speakers. You are actually going to need to measure the load of the speakers on the amp. If it ran too low of a load, meaning less than 4 ohms, there is a good possibility that the amp overheated and damaged some internal components due to not enough resistance. Some of their amps have internal fuses that can be replaced. It may be time to visit a diagnostic shop.

Good luck!

I have a old 2001 rockford fosgate 2 channel p5002 model in great condition just need to know how many watts is it and which subwoofers are compatible to this amp? thanks

Your amp is rated at 500 watts. Here is the break down of your wattage.

125x2 at 4 ohms
250x2 at 2 ohms
500x1 at bridged 4 ohms

When hooking up the amp make sure to use 4 gauge power and ground wire.

Which subs to use with the rf punch 8002

You should get the dual 4 ohm version of subs and wire them both in parrallel and series for a 4 ohm load to that amp, Bridge the amp and your subs should be seeing about 960 watts true rms.

What is the output of the 451s rms power

Dynamic Power Rating (measured at 14.4V):
  • Bridged Into A 4-Ohm Load: 450 watts x 1
  • Per Channel Into A 2-Ohm Load: 225 watts x 2
  • Per Channel Into A 4-Ohm Load: 115 watts x 2

Wiring for 2 subs for max performance

This amp is rated at 500 watts into a 4 ohm load bridged mono or 250 watts x 2 into 2 ohm load stereo. Do not go below that impedance in either case. The amp was meant to dissipate a certain amount of power, driving it to hard will lead to damage. Your speakers look like they are dual voice coils @ 4 ohms each. To get the max power while still saving your subs would be to parallel the voice coils on each woofer then run them in stereo with your amp. Stereo 2 ohm is 250 watts per speaker.

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)

    Amplifier loads

    Hello ronnieyannon,
    A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

    I'd wire them the way you have them wired.

    Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

    Hope this helps.

    Rockford fosgate punch 700s gets very hot

    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.

    Sub woofer wiring

    If you have a 500a2 and two 4 ohm single voice coil speakers, you have only one option. Connect one speaker to each channel.

    Rockford Fosgate 800a2 To 2 SVC 2ohm subs

    Ok.. Bridge the two sub into 4ohm than bridge to amp.

    So. this how it goes.

    sub1 + -
    to      | |
    sub2 - +
    =      4ohm

               From Sub
                -          +  
                |           |
    amp (L) - + (R)- +

    This will use the full potiental of RF 800a2 amp. I believe it like 1153 watts max out.
