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.
eyp, most of the time speaker connections blow and fuses wont stop that from happening. They are there to stop the mainboard from frying and not working at all. try running rca splitters to the operational side of the amp. run the sub on 1 channel. you will start hearing a difference but both sides will work. if not, run the splitters from the head unit and bridging it. these are the cheapest solution i could provide
well id say you have cooked your amp and or subs they can only take beatings for so long. show it no mercy it gives it back,does amp smell do subs smell borrow amp see if subs are ok if so it will be your amp.new one .keep the gain down??
Is the amp being fed directly from the head unit's RCA preamp outputs or is it being fed by another amp's preamp outputs? Try temporarily wiring up a speaker you know is good in place of the sub and see if anything changes.
