No Sound I replaced the JVC stereo in my 97 Mustang with my Jensen CD3720 car stereo and although the color coded wiring was the same on both stereos, once all was connected I had No sound but power to everything. Any ideas?

Check for a short. I experienced the same thing in my '86 F-250. Wires were replaced using a larger gauge, and crimped connectors with heat-shrink. Worked great.

What is the color code for the stereo in a 2004 chevy venture


I'm sorry Brando, but I do not know what you are referring to by "color code" for the stereo. Factory stereo? Wiring harness color coding for an aftermarket stereo? If you could provide more information about the problem you are having I'd be glad to help you, Thanks...

I have the jensen cd3720 cd player and it stop playin music and comes back on by it self what can it be that makes the radio do that


Hi there,

Are you losing complete power? Or do you have power, but losing sound only?

Loss of Power:

If you can access the wiring loom of your Jensen, check the RED ignition wire to ensure its secure - this wire is responsible for powering the unit ON (with key ON) and OFF (when key is OFF). A multimeter will be a useful tool to check for power when key is ON.

If the RED wire is fine, then there could be an issue with the power supply on the unit. Check the fuse on the Jensen unit - if ok, then there is a fault in the Jensen unit.

Power, but no sound:

The unit is faulty and will require service (or replacement).

That's because the memory wire has not been connected to a permanent live supply.

There will be an ignition switched 12v supply and a memory wire. The first is yellow on many brands and the second is red, but you need to refer to your fitting manual to check or look directly at the wiring harness as the wires are often individually labelled.

Since they both take 12v some folks mistakenly think that they can just be piggy-backed to each other and feed from the same supply. They can, but only if it's to a permanent live feed but that then leaves the risk of the unit being left switched on when the car is parked and draining the battery.

Need to wire JVC model KD-G340 into a 97 Kia Sephia


Do not cut the wires from the car. Instead, call Crutchfield at 888-955-6000 and order the adapter part number 120701003. When you call them, ask for color coding. For JVC, refer to the attached picture. Match the adapter color code with that of JVC. If the adapter color code is the same, then connect ground (black), battery (yellow), and wire from ignition switch (red) securely. Turn on the car and see the radio works. If it works, connect one by one speakers and confirm. Remember, perfect connection gives reliable installation.

What color is what when installing a car stereo in a 91 Grand Marquis?


you can go to your nearst car audio shop and buy a harness that will plug into your factory plug, which will allow you to wire directly into it with your aftermarket radio harness which is color coded to match. the reason i recommend this is b/c some of the marquis are factory amplified. although i have included some wiring info for your car, be sure to test all wires with a digital meter first.

Jensen CD3720 car stereo unit face plate LCD display blanks out.


The substrait is probably cracked, that's the circuits inside the pc board of the faceplate. It will cost you too much to try to have it repaired. If you will wait for a few days I may have a face for it as I'm currently trying to fix one that is blowing fuses. I'm not going to spend a whole lot of time on it. I'll let you know.
