Replacement Sub-Woofer for X308 99 XJ8 with Premium Sound System

[Michael J.]

Has anyone found a subwoofer that will fit in the existing opening and can have both connectors that connect the four wires to the speaker hooked up? Sometime in my car's history, the subwoofer for the premium sound system was taken out. So I do not have one to use as an example. Ideas?

I purchased a Custom Autosound 6" X 9" Dual Voice Coil Upgrade Speaker Model 3006 DVC. I had to cut off the original factory connectors and use crimp on blade connectors. Wired as follows: Red = +, Blue = gnd, Slate = + and Pink = gnd. Speaker fit in factory location with factory grill. I did make four spacer blocks from 3/4" plywood 1" X 1/2"
