Rockford Fosgate Punch P5002 Car Audio Amplifier Questions & Answers
I have a Rockford Fosgate Puch 1000 watt amp "thermal" problem
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up without the thermal LED being lit, the wiring needs to be checked. If it still indicates that it's in thermal protection, it needs to be serviced. A local repair shop will be the quickest. Rockford will email you the schematics.

Cooling fans are your friend. You can power them with the remote and ground terminals on amp.
.A thumbs up would be greatly appreciated if this answer is helpful to you.

check the OHM resistance on your subs. do not go under the minimum OHM value.remove the power wire and retry again, if it does the same thing the amplifier needs repair.try:ampmedics.netor sell it for parts on ebay
How do I put my car stero in auxiliary mode
how to put your amp in aux mode is that the question? I would think that your head unit should be taking care of the aux modes. Your amp is only going to amplify the sound sent to it it's not like a home stereo that has a preamp built in that's what the head unit does on car audio.
Rockford P5002 amp problem with thermal light and low voltage
Hello rbenwalker,
The voltage drop may not be in the actual power wire itself. The same reading on both the B+ and remote terminal probably points to a bad or high resistance ground. Try a different ground point or make sure there isn't any corrosion, paint or anything else preventing metal to metal contact.
Hope this helps.
Rockford p5002 amp is smoking...
Completely disconnect the amp and remove the cover. Look for anything that is discolored or burned.
Did you have one sub on each channel before the sub blew?
How do u connect the amp
Run a power wire from the positive battery terminal to the red power wire on your amp.
Without extending the length of the ground wire if possible connect it to a clean ground connection as close to the amplifier as possible.
Wire your speakers to the proper terminals, make sure you do not exceed the capabilities of the amplifier i.e. impedance matching.
Connect the blue wire to the power ant or remote connection on the back of the radio usually a thin blue with white stripe or plain blue. screw amp to the car..enjoy
My amp keeps cutting out the subwoofer... I
Your problem is probably that your amp is starving for power. I have a few questions.
1.What size wire are you using for power and ground on the amp?
2.Whats the impedance of your Sub-woofer?
3. How long are the power wire and ground wires.
For starters... I'm going to guess that you usually lose the subwoofer at lower frequencies. The lower the frequency the more power it requires to drive the sub. You also might want to check if you are running the amp bridged but mainly if your amp is trying to push a 50hz tone at high volume, If your alternator cannot provide the required Amperage. The amp will cut out. A capacitor can improve this. Run a power wire from the battery to the positive terminal of the capacitor then from that same terminal run a positive wire to the amp. Connect the ground on the capacitor directly to the body of the car...make sure to scrape off any paint to make a good ground connection.
The thermal and power lights
check your connections, this usually indicates that you have a short circuit but also make sure that your earth strap is securely fastened to a clean metal fixing.this could well be the cause of your problem.
