Disconnect all speaker wires from the speaker terminals of the amp and disconnect the RCAs. Replace the 30 amp fuse with a 15 amp fuse. If you turn it on and it blows the fuse, it's likely that it has shorted output transistors. If that's the case, you need to have the amp repaired.

Received a RF P2002 for Xmas want to install in my PU to power 12 in woofer I can figure out the input do I just connect the woofer to the bridged + and - or is there something I need to do to get thi

this amplifier is a 2 channel 50watts rms per channel and would not really be powerful enough to drive a subwoofer of any substance for car use, however , bridging it would give you 200watt rms into 4 OHMS but your subwoofer would have to be a single 4 OHM voice coil. Best you use this amplifier to drive a pair of speakers.
Hope this helps. let me know if I can further assist you

How to get 2 omhs

Look on your speakers to see what ohm they're rated at currently. To get 4 ohm speakers to 2 ohm, simply wire the speakers in series. Meaning that you hook #2 sub to #1 sub and then to the amp. So you will have 1 connection to the amp but you'll be operating 2 subs. Hope this helps

Im looking at this rockford fosgate p700-1bd amp brand new for $300 it comes with a birth sheet it says 750 rms on a 1ohm load. i cant find any reviews about it 225 rms x 1 @ 4-Ohms 450 rms x 1 @ 2-Ohms...

You can't go wrong with Rockford, in my opinion. Everything they make is well built and high quality. I personally have two Rockford p500-1bd amps hooked up to four 12 inch subs in my car and those amps make those subs slam. I have them wired down to 1 ohm and the specs say that they should be pushing 500 rms a piece at 1 ohm so that p700-1bd amp really packs a punch. Depending on what you're hooking up to that amp I would defenitely recommend it to you. - Ryan in Alaska

I have a old 2001 rockford fosgate 2 channel p5002 model in great condition just need to know how many watts is it and which subwoofers are compatible to this amp? thanks

Your amp is rated at 500 watts. Here is the break down of your wattage.

125x2 at 4 ohms
250x2 at 2 ohms
500x1 at bridged 4 ohms

When hooking up the amp make sure to use 4 gauge power and ground wire.

I have a rockford fosgate punch P325.1 subwoofer mono amp that blows a fuse every time i start the car. I have a second pioneer amp but that works with no problems. How can i fix this?

Is it the correct size fuse ? Is it the power fuse or remote ? Either way check your connections going into the amp . Try this hook your other amp to the set of wires for the rockford if that amp has a problem its a wireing problem if not chances are its an interal problem on the rockford . Hope this helps !

When i hook up the amp the protect light comes on. whats wrong

If all of your wiring is right, then that's a protection circuit telling you it's time to have your unit serviced by an authorized service center. Sorry for the bad news.

Need to know how many ohms this amp is

Safe down to 2 ohms, NOT a 1 ohm stable amp, it will be pushing it hard even at 2ohms but Fosgate's should be able to handle it providing that the install and all cables,wire,connections,etc. are sanitary!
Good Luck !
