Only fuse you need is the power wire leading to your aftermarket amplifier for te subwoofer. Which most likely you have too small of a gauge of wire and burned straight through it, and if you haven't, add a 40 amp fuse near the battery where your power cable is hooked up to. Also use a multimeter to test your power wire on amp, check the
A mono amp usually can handle only two 4 ohm subs. You see when you hook up two subs in parallel it drops the ohms too 2 ohms and 3 in parellal drops it to 1 ohms overheating the amp and cause power failure. Unless you bought a Mono amp thats 1ohm stable. But still I've seen cheap 1 ohm stable amps not last long. Also possible your subs are fried too check them with a multimeter and measure each sub ohms.
power source with inline fuse working. a ground line getting a good ground(scratch paint off care frame screw it down). remote line from amp connected to the remote line on the radio. and make sure you have rca running to the sub input on your radio. and your speakers are connected.
check to see if you have power going to the amp. Battery(+) and Negatve(ground). if those are ok, turn the radio on and check to see if the remote wire(it's usually blue) has power. if you have power on the battery wire and the remote wire from the radio, then there is a problem with your amp. check fuses on the amp if any.

You need to check the external power amplifier and the connections from the Pioneer and from the sub(s). If everything is plugged in and wired correctly, check the amp fuses, both on-board and the main power fuse (located in the amp positive lead usually near the vehicle battery).
