Remove the load from the amplifier (subs) and the RCAs
Retry.
If the light stays on, there are internal problems with the amplifier, and it needs to be serviced.
If the amplifier works normally, attach the RCA's and power on again.
If it remains on, connect one sub, and then the other.
Your amplifier is a 2 channel amplifier rated at
60 Watt - 4 Ohm - 2 channel(s)
125 Watt - 2 Ohm - 2 channel(s)
250 Watt - 4 Ohm - 1 channel(s)
Your amplifier is not rated for a 2 ohm mono load.
If you have Single voicecoil subs wired in parallel, you have a 2 ohm mono load - your amplifier will eventually fail.

I have a rockford p4004 and the protection light is staying on and am not getting anything out of the amp to my subs. what can i do. i hooked up a different amp to it and it worked fine.


The unit is internally grounded. Something has broken inside and grounding out the power, the amp will need to be serviced or trashed. Try calling Fosgate. They may have a serviceman or "fix it" department

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

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..

2 12 p3d212 2 ohm hooking up to a rockford fosgate p325 .1 mono amplifier can it work? and how?


Hello a_brake11,

The P325.1 is relatively small to power a pair of P3's. You'll only get 325 watts RMS at 2 ohms (162.5 watts per sub). The P3's power range is from 100-500 watts, so they will work, but don't expect them to be really loud.

For best power, your subs should be wired with the voice coils in series and then the 2 subs paralleled to the amp resulting in a 2 ohm load.

Hope this helps.

un hook the subs and let the amp sit there on if the protect light shuts off you wired your subs wrong if it doesnt go off tun it off then back on with no sub music all the way down then slowly turn the music up if the light is off then comes on you need new rcas

Sub hook ups


There's a lot more factors involved than that.
  • Power capability of the subs
  • Type/size of the sub box
  • Allotted space in the vehicle for the sub box
  • Voice coil impedance of the subs versus the capability of the amp
  • Etc.
