Ok so i have a rf p3001 and i seem to have a sound problem or something because when it turns it doesnt produce any sound and when i try to turn the gain up to about half way the amp goes into protection mode.
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

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.
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
RF-B65 has a known issue with the power connector on side. It gets resistive from not being used. If you apply 6 vdc and it works, its most likely the batteries or the power connector. If both produce a "E" its PLL doesnt lock. Power plug most likely issue. Another issue is the tuning knob. It skips or jumps irratically. The up/down frequency changes are by a cube 1/2 inch square contactor. Its not optical. Just simple mechanical contactor. Remove the small cube from chassis and spray liquid gold. It will clean wire contactor and lubricate internals. You cannot buy the cube. Cleaning it always works for me. RF-B65 radio is a sure winner. Small, reliable and very sensitive. Has SSB also. eter
check and make sure all powers (12v) and remote ground are were they should be then check signal outputs is in the right spot comeing from (THE Radio) to THE AMP imputs.THEN CHECK ALL OF THEM AGAIN. if thats not it you will have to bring it to someone like me and be charged around $30 an hour to fix.
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!
