Re: aftermarket stereo install

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.

Can't suggest anything except go to and search out your vehicle's wiring info. Couple guys I work with used that site with success on their aftermarket installations.
Good luck,

What is a anti theft device? what is passlock?

well most newer cars have the anti-theft,vss,or other BS, wired thorough the radio harness for whatever reason they felt. however they now have by-pass modules for most aplications.

check this out. If you take the factory radio face (rack of buttons) in a 01 ford focus the car will not start, or if you turn the car off, and push the volum knob to turn the radio on for one hour then lock the doors from the remote, the remote will no longer unlock them without being re programed(after you break-in to pop the hood and cut power and then re-program)....fewww!!

I'd say go back to the guy who installed and get him to do it right. He's either left some wires exposed so they are intermittently touching, or has an open connection to one of the speakers. The amp will shut down to protect itself. He may also not have wired the speakers correctly. Some systems don't work unless both hot and ground wires run directly to each speaker. Some installers run only a hot line and use the car body for ground. At higher powers this can cause amp shutdown or keep it from working at all. In any case the installation wasn't done correctly.

You could get a stereo installation kit for your year, make & model, that comes with a pigtail plug that would plug right into the existing harness plug and prevent you from having to hack up your original wiring harness.

If not....

Car Radio memory Constant 12v+ Wire: Orange
Car Radio Accessory Switched 12v+ Wire: The radio harness does not provide a switched power source. Run a wire to the fusebox for switched power.
Car Radio Ground Wire: Black/White
Car Radio Illumination Wire: Gray
Car Stereo Dimmer Wire: Brown
Car Stereo Antenna Trigger Wire: Pink
Car Stereo Amp Trigger Wire: N/A
Left Front Speaker Positive Wire (+): Tan
Left Front Speaker Negative Wire (-): Gray
Right Front Speaker Positive Wire (+): Light Green
Right Front Speaker Negative Wire (-): Dark Green
Left Rear Speaker Positive Wire (+): Brown
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Dark Blue
Right Rear Speaker Negative Wire (-): Light Blue

Good luck

Installed a clarion radio it powers up but no music thru speakers

sounds like a short in your wiring to your speakers the best thing to do to check this is run a speaker wire directly to the speaker from the stereo check it that way and see if it works.If that don't work it's the wires on the stereo connection.The speaker wires on most aftermarket stereos are mostly colored 2 of each green,purple,white & grey.

2005 jeep grand cherokee laredo aftermarket CD player installation

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!
