I have a 2005 E320 CDI, there was no subwoofer in the back. I checked with the VIN and it tells me that there should be a subwoofer PN 211 820 00 02. Strange ... it was not there. This is one large speaker only



Can anyone suggest if I can install it? I ordered one, it has two connectors, and two crossovers on it. I didn't see any cables in the back of the car, but I was able to find them if I take the rear deck out.

Also, will I be able to install the subwoofer that has the two mid/high speakers instead? 211 820 28 02, 211 820 28 02 and 219 820 06 02 (Harman/Kardon)



In addition the kicker panel speakers in the front don't sound at all. I removed the speakers, they have 8ohm resistance, and appear to be working with a battery, but I can't hear them.

Any help would be greatly appreciated!
