Capacitors are blown on the output side most likely. That amp isn't made for subwoofers. It will cost about 100 bucks plus shipping to send it to a competent electronics shop that has the ability to to that. If you are handy with a soldering gun, you have open it up and look for blown capacitors and replace them yourself. They sell them all at Radioshack.

Rockford Fosgate P450.4

There is no reset button on the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low. If both are above 12v, the amp will require servicing.

Hooked my punch Punch P450.4 up to speakers and ran rca cables to front and it wont work

Hi Jon, you need to hook the Remote wire up to the Radios Blue remote wire. The car battery power stays on all the time. The blue Remote wire watches to see when the radio turns on, and signal the amp to turn on as well.

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 .

Can I run 2 12 inch 2ohm fosgate and a 4 ohm 12 on a rockford fosgate 401s 1200 watt amp

Yes. Wire the two 2 Ohm speakers in series and connect them to one channel. Connect the 4 Ohm speaker into the other channel. This will give you a balanced 4 Ohm load on each channel.
