Amp Adapter with new stereo

Ok, so I bought a new Kenwood CD/iPod head unit to hook up to my otherwise stock system.

Included in the package from Crutchfield is one of those amp adapters that plug into the RCA style speaker jacks and then into the factory harness.

I get everything hooked up, solder all the harness connections for the power, antenna, amp power, etc. NO SOUND!

So I'm messing around, checking connections, etc, when I pull out one of the RCA plugs. When it's most of the way out (only the center point is making contact) I get sound. I do this to all of the 4 speaker connections and they do the same thing. Basically working without the outer portion of the plug making contact.

Crutchfied thinks it's a bad adapter. I think so too. It looks hand wired so there is room for error. They are sending one to me ASAP to see if that's the issue.

Anyone else have this problem? Any ideas?
 
What's the best way to do this? I want to preserve the stock setup as much as possible in case I decide to sell the car at some point.

An upgraded stereo system can only increase the resale value...the stock system is lame compared to today's equipment.
 
Well there are lines going into the amplifier, and lines going out. You will need to just splice the wires going into the amplifier, into the wires coming out of it. All you should need to do is splice the speaker wires into each other. Call crutchfield, the might have an amp bypass kit for you. I got mine free when I ordered 4 new speakers for my tbird... and it was a harness and like 12 feet of wire!!! Find a wiring diagram and you should be good to go!!

EDIT: Found this.. this should help.
