Re: RF P3001 power problems

Check your sub woofer connection if you have multiple subs the could be wired in a parallel or with has to many ohms that my cause it to not hit right and cause the amp to get really hot and cut in and out

I just installed a new xo vision x349nt dvd receiver in my car . My rockford fosgate p3001 amp turns on but the subs doesnt come on but when i would take the base control out and put it back in i can hear...

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.

I need a schematic for a RF p300-1 amp. Im trying to replace 2 of the mosfet semiconductors that got fried.

There are no schematics for RF amps, normally RF uses standard IRF Mosfets. Can you decribe the area where they blew, Power Supply are usually N-Channel high current type. Outputs can be either N-Ch or P-Ch depending on the Power rail there attached to.

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

What Hz do i use

The best way to set up an amp is to start with everything on 0 Turn your gain all the way off, then turn the stereo up as loud as u would normally listen to it. With the stereo on, slowly turn the gain up until it sounds the way you want it. As for the Hz settings, for a sub you should have the crossover set to lpf, and the z knob adjusts what frequency your sub will play. Since you have a 10" sub, I wouldn't put it much below 125, because tens can't produce ultra low bass and it could damage the sub. Hope his helps :)

Tighten very good the ground wire to your amp, then clean the metal where the ground attaches to the car chassis. Then tighten the ever lovin' bejesus out of the chassis ground. Yeah, I'm from the South :)
Good Luck!
