Back speakers won't work

I installed a radio in my friends Honda Prelude 1991. I'm fairly certain that I hooked up all the wires correctly, but the back speakers will only come on when the radio is very loud. And they speakers don't stay on, they kinda go in and out. Any ideas what the problem could be? Thanks

I have a 1991 ford festiva i changed my radio and now my shifter and my dash lits dont work are they wired in with the factery radio


Hi, the factory radio uses the illumination wire, but the aftermarket radio does not. You have to make sure that wire is taped off so it doesn't short the illumination circuit. Check your tail lights fuse. If it's blown, pull the head unit and disconnect/tape off the illumination wire (blue with a white stripe) from the factory harness. Then put in a fresh fuse. If you have more questions, please specify the model of the head unit.

Model-m 255 clarion installed in a pontoon boat. RADIO WAS WORKING JUST FINE, THEN I INSTALLED A (NEW) BATTERY FOR MY BOAT, HOOKED EVERTHING BACK THE SAME WAY. NOW, I HAVE POWER BUT (NO) SOUND...


Disconnect all the speaker leads and then hook one speaker (a new, known to work speaker) up directly to the radio using a short (6"-12") piece of speaker wire. Does that speaker work then?

Disc can eject and be inserted but display does not light up, none of the buttons do anything. tried a different deck and it does the same thing the display dosen't work and no music plays. i am thinking...


It sounds like they messed up your installation. You can confirm their work by verifying that each wire was attached properly.

2005 Pontiac Sunfire Car Radio Wiring Diagram Car Radio Battery Constant 12v+ Wire: Orange

Left Front Speaker Positive Wire (+): Tan
Left Front Speaker Negative Wire (-): Gray
Right Front Speaker Positive Wire (+): Light Green

Left Rear Speaker Positive Wire (+): Brown

Right Rear Speaker Positive Wire (+): Dark Blue
Right Rear Speaker Negative Wire (-): Light Blue

Click on this link for a PDF of the installation instructions of the radio (If you don't have the installation guide that came with the radio).

Illumination is the grey wire from the car to the orange with white stripe from the radio.

I suspect that the yellow wire from the car is not connected properly. When the orange wire (constant power from the car) is attached, but not the yellow wire you can insert and eject cds, but it will not turn on. Constant power is used for maintaining the clock and preset radio stations.

If everything looks correct, I would take your car back to the installer and have them correct the issue.

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.

Chevy Tahoe radio wiring problems


I had the same problem and here's what fixed it. By default, I did not connect the blue/white striped remote wire to the harness. Apparently there is an amp somewhere in the vehicle I did not know about. After looking at the factory wiring and the aftermarket harness, I noticed that the remote wire was used and I connected it with the remote wire on the harness and everything came up and worked perfect.

Trying to install after factory radio in 94 Honda accord ex and can't get any sound


I have a 93 accord ex with the bose amp system. Had a Sony deck put in it. It had the popping and the noises. It was installed at a store and they had to hook the red power wire to the antenna wire to get the sound to come out of the system when playing a CD. I thought that was bogus to have the antenna up all the time so I took it back out and put another quick hookup harness in it and it did the same thing. Will not put out any sound till the red power wire is hooked up to the antenna wire so that it goes up when the key is turned on. Installed the same stereo in a 94 taurus SHO with amp and it worked great. I believe that there is an expensive kit that converts the bose system to hook up a unit so that it doesn't pop click buzz, and have to have the antenna up to play.

Static thru speakers at mid-high volume all the time


Your head unit may not have a common ground for the speakers. If you have two wires for each speaker coming from the head unit, rewire the speakers for a floating ground, that means two wires per speaker, or use a floating ground adaptor. These radios now a days are NOT like the radios in the hay days of care audio. If you already did not cause any damage to your unit, you certainly will if you continue to use it the way it is hooked up now. Good Luck
