Question about Rockford Fosgate P3001 Car Audio Amplifier
When turning the vehicle on thus providing power to the amp the woofers that are wired to the amp suck backwards and will not move forward again until the vehicle is turned off
I have the same problem and two of the transistors are burnt out. Where, other than Rockford, can i get some new ones?

Hi. Your amp is cooked. How to chekc fo rshorter output transistors? use a ohm meter take the amp apart and using the ohmmeter ohm between pins #2 and #3 of each output transnstor. THose outputs that read anywhere near 0 ohms are either shorted or are in the same series as the shorted one. The whole series of transaistors should be replaced not just one transistor. On the rockford fosgate amps they solder the transistors down to a heat sink. THis kind of work should definately be left to a professional as if an amatuer tried to do this repair he would ruin the amp.

If the speakers are being driven in or out and remain there when the amp is on, the amplifier likely has shorted output transistors. These are not easily replaced in the Rockford amplifiers that use the MEHSA insulators. Unless you're interested in learning to do this type of work, it should be sent to Rockford for repair.
