Question about Pioneer Car Amplifiers
FACTORY AMP WAS CUT LOOSE AND I NEED TO CHECK IT TO SEE IF STILL WORKING PROPERLY OR ORDER A NEW ONE - PLEASE SEND ME THE WIRING SCHEMATICS OR PIN CONFIGURATION OF INPUT AND OUTPUT SIDES - THIS AMP ALSO HAS A FACTORY SUBWOOFER OUTPUT - PLEASE INCLUDE THAT AS WELL - CALL IF YOU LIKE MY NAME IS JON HAYWOOD CELL # (919) 770-1292 OR WORK # (919) 775-7311
here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem

Apart from the external DC power fuse (I hope you have one in-line), the majority of in-car amps have 2 mini fuses inside the unit to protect the output MOSFETs from overloading due to incorrect speaker connections, ie, if the output impedence is rated at 4ohms, anything less than that is considered to be a short circuit, and will overload the MOSFETs. After performing the tests suggested by KaeZoo, open the unit and look for printed markings on the circuit board, something like F1, F2, the fuses may not look like conventional fuses.

You will need the following:
A power wire (preferably 4 or 8 gauge) with an inline fuse (typically 50amps)
A battery terminal adapter to connect the power wire
A signal wire to let the amp know when the stereo is on
RCA audio cables to connect the amplifier to your stereo
A ground wire for the amplifier (again 4 or 8 gauge preferred)
Walmart sells a Scosche kit that has all of the wiring as well as a basic diagram for about $25, but it does not include the battery terminal adapter.
If you have a factory stereo you won't have RCA ouputs, so you will need a line level converter. A basic one like the Scosche SLC4 usually runs in the $20 range. You splice into your speaker wires and run them into the unit, then plug the RCAs into it.
