So I finally got around to playing with my deck and I ran into some problems.

I picked up an amplifier integration harness, like many people have talked about in this thread, and I plugged it into the wire coming to the stock deck, wired it up to my Eclipse deck and..... nothing. No power.

So I then went and hooked up the stock deck back to the connector, and more nothing.

I ran a straight wire off of the battery to the stereo and I was able to get my Eclipse head unit to power up, but not using the harness.

After going through every fuse and testing the voltages coming into and out of the various connectors, I have concluded that I am losing power going through the amp. I think hooking up my deck with that harness somehow fried the stock amp and now I have no choice but to bypass the amp and use the blue connectors underneath.

I'm rather pissed off that this happened because the amp integration harness is such a quick install compared to this crap...

And odds are not all 6 front speakers will work anymore so I have to either rewire them in series, or go and get another amp, which is not what I had in mind.


Does anyone know if the stock amp handles crossovers to the tweeter and such or is there a voltage blocker inline for the tweeter? I'd hate to hook up everything and blow it.
