I have a kenwood kdc-x396 aftermarket car stereo that I am trying to install in my 2000 Jeep Grand Cherokee. I have the harness plugged in and everything, and I have power to my faceplate. I can switch between all of the settings and functions, but I have absolutely no sound coming from my speakers, not even the beep you are supposed to get from switching functions.

you have to get into the menu. Here is a link to the manual to help you do it. http://inform2.kenwoodusa.com/manuals/KDC1028.pdf

Was it working before?

I would hate to have you crack it open when maybe the ground wires arent hooked up right. Unless you have a scope go online and get the manual on wiring it to ensure you did it right.

Here's the quote from the manual regarding "dcer": "The speaker wire has a short-circuit or touches the chassis of the vehicle and then the protection function is activated. Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT/DCER" code does not disappear, consult your nearest service center "

I believe the manual can be downloaded from crutchfield .com after you go to the Kenwood KDC-138 page on their website. The reset button is either on the lower left of the face or, removing the face, on the lower left of the body. Hope this helps you.

Unsightly gaps as in how?? I know the kits anymore give you, usually, diferent mounting depths and whatnot. You get alot more pieces than needed but options are always good! This I know was true with the GM/Pontiac kit I just installed for my stepfather. Looks good, doesnt protrude any, other than just the face!
