Unit on,no sound from speakers,no green light from speakers

Did the dealer replace it?

Hi, have you find any solution? I got the same problem. Can you please email me. [email protected]. Thank you

Dose the green LED light up at the front ? . If it does not its a power supply issue. You must have burnt the transformer in the power supply unit. If the light lights up ans there is no sound it could be the Amplifier Chip (IC ) problem. This will involve soldering and desoldering work not to mention procuring the IC.Cos wise the IC just cost about 3$ ans the transformer about 7$.

The green light represents that the unit is receiving power, if the light is off then the unit is not receiving power. Check the power plug. Check the power switch on the speakers. You may need to push in a knob.

Take care!

if you have stereo speakers, connect it to the green audio port on your computer. if you have digital surround, you have green, yellow and black. insert the speaker connectors accordingly.

Hello chrisuftring,

Here's a link to the wiring color code for the '95 Chevy Beretta.

You'll need to match the function of each wire from your head unit and the color code for that would be in your manual. Most aftermarket units are somewhat standard as far as power, accessory, ground, and speaker connections are concerned. But the wiring colors may be different for such leads as remote, power antenna, illumination, dimmer, and muting.

An Alpine head unit has the following wiring colors:
Blue - Power Antenna
Blue/White - Remote
Pink/Black - Audio Interrupt (muting)
Orange - Illumination
Red- Switched 12V+
Yellow - Constant 12V+
Black - Ground
Gray - RF Speaker (+)
Gray/Black - RF Speaker (-)
White - LF Speaker (+)
White/Black LF Speaker (-)
Violet - RR Speaker (+)
Violet/Black RR Speaker (-)
Green - LR Speaker (+)
Green/Black - LR Speaker (-)

With this head unit, you would wire Yellow to Orange, Red to Yellow, Black to Black, Orange to Gray, Blue to Pink, Gray to Light Green, Gray/Black to Dark Green, White to Tan, White/Black to Gray, Violet to Dark Blue, Violet/Black to Light Blue, Green to Brown, and Green/Black to Yellow.

Note that there are 2 "yellow" wires in your vehicle color code. You'll have to test them to determine which one is the accessory wire and which one goes to the left rear speaker. Using a 12V "test light" is the simplest. Connect one side of the light to ground. With the ignition ON probe the yellow wires. One of them should light the tester, the other one won't. Verify that the light goes out when the ignition is OFF and your have separated the redundant "yellows". The one that lit the tester is your 12V+ switched wire and the other one goes to the left rear speaker.

Hope this helps.

Yes the green wire that goes from the speaker should be plugged into the green jack on the PC. An easy test to see if its the computer or the speakers is to have the speakers on and volume up a little and tap the tip of the green plug with your fingers while out of the computer. If it makes a humming or any noise at all while tapping, the speakers are working if not lets check voltage at the power plug or if the unit has any lights on. Gook luck!

We just hooked ours up and had the same problem, we switched around the s-air cards and that solved the sound problem immediatly.

The factory wiring connector hook-up for the Mustang is:

Radio / Power Connector:

Light Green / Yellow - Hot at all times (Fuse 8)
Yellow / Black - Hot in ACC or Run (Fuse 11)
Light Brown / Red - Goes to instrument panel dimming rheostat (Fuse 4)
Red - Ground
White / Purple - Hot in ACC or Run (Fuse 11)

Speaker Connector:

White / Light Green - (+) Right Instrument Panel & Door Speaker
Dark Green / Orange - (-) Right Instrument Panel & Door Speaker
Brown / Pink - (+) Right Rear Speaker
Pink / Light Brown - (-) Right Rear Speaker
Pink / Light Green - (+) Left Rear Speaker
Tan / Yellow - (-) Left Rear Speaker
Light Brown / White - (+) Left Instrument Panel & Door Speaker
Orange / Light Green - (-) Left Instrument Panel & Door Speaker

Your best bet is to buy a radio install kit and adapt it to the Mustang connector. Hope this information helps.
