you should be able to get a new wire harness at any decent car audio store.

go to crutchfield.com they have install videos

you can do one of 2 things , run wires from each speaker to the head units speaker wires or locate an amp bypass harness from www.metra.com, sometimes theres a tiny amp on each speaker as well , i doubt it for the year of youre truck but it may have at least a factory amp . u need that bypass harness

check wiring on passengers side near the rear hatch speaker, the rear door speakers are run through them also. i had the same problem and it was a unplugged connector at that location

Hello violentj_1_u,

Yes, the amp can be used to power normal speakers on 2 channels.

The best way to wire the amp to a stock receiver (head unit) is to use a pair of wiring harnesses, one the standard harness that plugs into the vehicle wiring, the other a "reverse" harness that plugs into the stock receiver.

First remove the plug from the receiver and plug in the "reverse" harness. Run the speaker leads from the reverse harness to your amp inputs or to a line output converter (LOC) and RCA's to the amp. Then run the amp speaker outputs to the standard harness speaker wires. Plug the original receiver plug into the standard harness and splice the remaining wires, 12V constant, 12V accessory, ground, illumination, etc, together. Connect the 12V switched wire to your amp remote terminal.

Hope this helps.

You can go to Walmart and in the stereo/speaker department they have dash kits for different vehicles.Just read the box to determine your vehicle. Also, they have amp kits for different wattage amps, but if you had rather buy each item you will need, a Power Wire (to the battery 4g or 8g), a ground wire (to the chassey), a remote wire that should run to a wire from your cd player saying remote (any size is fine), speaker wire (14g or 16g is fine) a set of RCA cables, and if your cd player dosnt have RCA jacks you will have to have a converter.

I had this same problem. After reading other ideas and some trial and error, I finally got it. Most Caravans have an Infinity system (the speaker grill will say Infinity on it) ,which uses an amplifier to run the door and rear speakers. I had to ground the clip wire that was originally attatched to the strap ground on the factory installed radio. Then I also had to hook the wire on the new radio for power antenae (blue and white on my unit) to a blue wire on my new harness. This wire came from the last wire of 7 wire harness that had the other 6 wires for speakers. The original wire appeared to be green/red on my vehicle. After I connected both, the speakers cameon and sound great again

You need to attach the blue wire on the stereo harness to the blue and white wire on the car adapter harness. they installed a small amplifier to power the rear door speakers and unless you connect those two wires then the speakers will not work.

I had the same problem and here's what fixed it. By default, I did not connect the blue/white striped remote wire to the harness. Apparently there is an amp somewhere in the vehicle I did not know about. After looking at the factory wiring and the aftermarket harness, I noticed that the remote wire was used and I connected it with the remote wire on the harness and everything came up and worked perfect.
