Re: My amp is blown!! Dont know what part to replace.

You have a bad mosfet. The output fets in the P6002 are FQA 28N15 and FQA 36P15 easily found at mouser, digikey, or allied electronics. Without a pic I could not know if you need power supply fets or output fets. Its an easy fix if you know what you are doing. Desolder the bad fet off of the mesha board, tin the new mosfet and resolder it back to the mesha board and replace your gate drivers and emitter resitor for that fet that was bad. Might check all of them with a meter to be sure. You can call Rockford and order a whole new mesha board and solder it to the pcb yourself. Be sure to use new silicone heat transfer compound. MG chemicals has some nice products.

Re: My amp is blown!! Dont know what part to replace.

Those are likely "chips" or "integrated circuits". can you read any words, letters, numbers off it? if it's a common off-the-shelf chip you can buy from or, AND if you know how to de-solder and solder delicate electronic components using a hot soldering iron WITHOUT destroying them or the adjacent components. if no identifying codes on the chip, maybe google up a schematic of the board (unlikely) and figure out what it is. if it's a proprietary chip made Rockford Fosgate, it will be harder to find. Also, there could be damage to OTHER components that may not be visible, so if you go to all this trouble it might still not work and then you'd have wasted money. hopefully you are under warranty and RF can repair it. otherwise, chunk it in the nearest trash can.

Hi and thank you for using fixya:

I had the same problem in my car and it is a simple fix. You have to make sure that the subwoofer speaker and amp are no more thank 1 feet apart.

good luck

Rockford fosgate p 300-1 amp will not turn on

plug your ground, battery, and remote wires only and see if it turns on when you turn your radio on, if not it must have blown. wiggle or move the connection block(where your wires are connected) and see if it tries to turn on. if so, your leads need to be re-soldered since they tend to go cold(they're not making good contact). But again, if that does not help, then your amp is gone.

I have a rockford fosgate 550 that the fuse blows

Short inside one of the transistors. This requires very good soldring skills and electrical know-how, and some thermal paste to go between the heat-sink and the transistor. Unfortunatly this is not a cheap repair, probably cost around 100 dollars.

I was given a rockford fosgate 500x 4 channel amp and the rear 2 channels work fine but the 2 front dont when i hook up the speaker the speaker bottoms out and stays like that until i unhook the speaker...


Sounds like those two of the channels are blown. There is really nothing that can be done about that other than having an expert repair it. You might as well buy a new one tho, or just use it as it is.

You could look at all the fuses in it, make sure there not blown (they will be black and the little metal piece inside the plastic will be broke or cracked)

Post back if you have any further question's and comments. Thank you for choosing Fixya!

Rockford Fosgate T15004 The Amp still powers up with the

Check you inputs to verify you have a signal coming in, if signal then check outputs try a speaker that you know is working and plug it in if that speaker plays then the subs/ or speaker wiring is bad, if it doens't play then you probably have a blown output transistor on the amp or possibly a terminal ground/positive has come loose on the inside..
