amp is way too small to power a 15 inch sub. But you should get some sound out of it, not silence. You can use a 9 volt battery to test your sub, if the sub pops when the 9 volt is placed across it's terminals then it's ok. If it does not pop then your sub may be bad, or the coil may be frozen. (It can still read 4 ohms if frozen). If your amp powers smaller speakers fine, you know it's not the amp. If the sub tests ok, then verify your connecting it properly to the amp's correct bridging terminals.

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.
I have a Rockford Fosgate 1500 BD amplifier and terminals for the power cable will not loosen or tighten how do I fix it
First off will the fastener turn ? If not try using a bit of wd-40 and letting it "soak" for a little while . Also be sure you are using a good proper sized Phillips screwdriver . If the fastener still won't turn try using a can of "computer duster " inverted so the liquid comes out , note this will be well below zero degrees , and freeze the screw head , then try turning . If the fastener is stripped and the ttol slips you will have to remove the amp cover and grip it with a pair of vise grips ,pliers or a flat blade screw driver .
