Two steps forward and one step back.

Installed the small backup camera in the lid. There are two holes in the underside of the lid with grommets in them. I used the driver's side hole and put the camera in there. Ran the wire down the cable wrapping on the passenger side and on through the back seat area.

I rebuilt the surround on the two back woofers It seemed like things were going good. Got things partially back together and utilized the original head unit. Noticed a buzz on the driver side woofer during heavy bass. Took the woofer cage apart and it appears that the voice coil was dragging. (shucky darn).

So now I have switched to the Kicker subwoofers solution, and I ordered the forward-facing mount from the forum. Just have to wait for them to arrive.

BTW, the radio antenna is a standard connector on this original Crossfire GPS radio as compared to the European connector on the Crossfire base model radio. Looks like it has the capability of a CD changer based on the connector. On my other car, the European connector caused problems withthe original Chinese radio.
