Question about Rockford Fosgate P3001 Car Audio Amplifier

1 Answer

Stuck On Thermal Mode.

So I got the P3001 hooked up to 2 Rockford P2 12's. My amp is flickering Thermal but the amp isnt hot. Even when I unplug the subs its still in Thermal mode. Sometimes it will catch and the subs will hit for a minute but after that nothing but some popping sounds. Someone told me that the amp could be shorted out inside. Any Help?

Re: Stuck On Thermal Mode.

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, the wiring needs to be checked. If it still remains in thermal protection, the amplifier likely has an internal fault and will need to be repaired.

P3001 problem

if amp is mounted to back of the box try and move to in front of box near subs or port. the air movement of the sub will help keep the amp cooled. or you can orer some 12v cooling fans and take back plate of the amp and cool it that way. or you can buy higher quality audio, your choice

Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

Rockford P3001 amp not working

peel the cover completely off the amp and give it some power- if the amp is blown there will be a tiny light lit up on the circiut board that quite simply says "SHORT"-If its blown then theres nothing you can do unless you are a badass of course- but if the amp is dear to you and you want to spend a little money on it to get it up and running again- go to rockfords website and get into the forums and ask the question-where do i get my fosgate fixed and it will pull up some mumbo jumbo but it tells you about a place called LANDIS TECHNICAL that bought up all the parts to their amps and is in the business of restoring the amplifiers to their factory specs and even sends you a new power certificate to go with your new and improved amp.hope that helps you-

My amp wont give me any power

all the p series amps were discontinued for similar problems, they have a newer model out now. they have very weak boards internally and failed faster when mounted to the sub enclosure or very close to it from subsonic vibration. i would guess the amp is toasted.
