Need help on location of internal amp on the circuit board.
The problem is that i am not getting an output on my speaker leads but i am on my rca leads. I think tme internal amp is the problem. any help will be appreciated.
Re: internal amp description on the pioneer deh-3500
Look for a large integrated circuit that is bolted to the heat sink. It probably has about 15 to 20 leads coming out of the bottom edge. Be sure that if you replace it that you apply some fresh heat sink "grease" between the IC and the heat sink. Good luck and I hope you have a soldering iron and solder sucker.

There are no subwoofer settings on the Pioneer DEH-2800MP.
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).
There is a fine strip that runs from the face to the circuit board. It is possible that face has gotten dirty just needs a can of compressed air or the circuit board has failed inside the face.
The face plate is very easy to take apart and put back together, just make sure you don't lose any pieces ;)
some cars have internal amps for the speakers try connecting the remote wire it's the blue wire with a little white on it worked in my moms van.. if that does not work try testing it with a speaker from your house
