Try swapping over the rcas for instance if black is in r and red is in l then swap them so red is r and black is l

if that doesnt work try swapping the subs over to as you may have a faulty sub. if that doesnt work then check the fuses on the amp

still no joy then i would suggest taking your amp to your local car audio dealer and getting them to have a look at it

Hope this helps if so please dont forget to rate

best wishes

Protect mode?


You added speakers in parallel which reduced the effective impedance to to a value low enough that your Rockford Fosgate amplifier had to enter protect mode to prevent damage to its output stages.

Rockford Fosgate P3002 stopped working


push down and up on your subs and see if they make a starching noise, if they do then they are blown. take a test light to the amp, on the power and the remote and see if it lights up. if it does then turn the amp down and with a small speaker plug it in to the speaker outs on the amp and see if it plays if not then your amp is bad.

How do u bridge the rockford fosgate p325.1?


Hello... sorry you are having a problem. If you are running the 325.1, that amplifier is strictly a mono-block amplifier (1 channel) so it is not possible to bridge it. There are 2 speaker connections on the amp but both positives and negatives are connected on the circuit board in the amp. Hope this helps. Good luck with your venture.

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..

Connect rockford fosgate amplifier & speaker together


Assuming your P3 has a single voice coil (it will have only one place to plug your wires into) you will be running this in a bridged mode. You will take the left (+) coming off the amp and plug it into the (+) on the P3. Then take the right (+) from the amp and plug it into the (-) on the P3. This will make your amp push 500 watts to your sub. Now on the amp make sure your adjustments are as follows: Signal input switch is set to unbalanced for RCA input. Left Phase switch is set to 0. Right phase switch is set to 180. your X-card should be set to low pass. And adjust the gain for both R and L equally so it has equal power from both channels.
