20 Most Recent Rockford Fosgate P3001 Car Audio Amplifier Questions & Answers


Your friend has damaged his amp. The power light coming on means that the amp's power indicator LED is at least working. That light is only there to tell you that the amp is receiving power on it's 12 volt rails, not that it's necessarily using the power in any way other than warming up the amp's internal circuitry. When you say the amp gets power, I'm not clear on whether you mean the amp works in that fashion, or there's just a red LED glowing but nothing else happens. The amp needs to be repaired, and I would suggest to him to not apply power to it again until it is checked by a professional. The power supply has probably been damaged, and it's possible, depending on how the amp was mounted, that it was searching for ground through the amp's chassis if it was screwed into metal at its mounting location. All that seems certain as of now is that the LED works, but nothing else, unfortunately.

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.

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Your amp is clipping.
No internal fuses. Your mosfets are toast. A thumbs up would be greatly appreciated if this answer is helpful to you. using-bridge-rockford-p300-blew-peeu4x5nsxvd53n2rwetiqa4-3-0.jpg

Make sure and check the RCA wires in the back of your radio that send audio to the amp and make sure that they're connected to the OUTPUT/SUBS RCA's and not an input rca's. Also, check your ground and make sure no speaker wires in the subs are shorted. Try one speaker at a time see if that helps.
