Need more info did it happen all of the sudden or after installation and do you have an amplifier for your speakers or no because this could go four different ways

SOURCE: No Sound

The audio not coming out from the speakers is normally the amp IC being bad.

If you have a bad speaker it could shut down the amp IC, but normally it will make the amp IC go bad if a speaker gets shorted.

Try disconnecting one speaker at a time and see if the sound comes back on any of the speakers. If so, you just found your bad speaker.

Or if you have a multimeter you can just check the speakers resistance. Each speaker should measure around 3.5 ohms to 4 ohms if it is normal.

Do the RCA jacks have audio? If you have a sub woofer connected to the radio, you would be able to hear the bass from it if the RCA jacks are working.

The reason I ask is, if you have no audio from the RCA jacks you may not have a bad amp IC.
You may have a bad electronic volume IC.

Are there any problems with the tuner locking in on stations?
The reason for this question is, the FM MPX is also part of the electronic volume IC.

If you plan on trying to repair it yourself, the first thing to check would be the voltage on the speaker outputs. If you have a voltage meter you would ground the black lead to the chassis of the radio or if the radio is still in the car ground it to the chassis of the car and then put the red lead on each one of the speaker leads. You can do this in the car at the speakers, but the radio must be turned on to check it. The speaker leads should all measure around 6.5 volts to 7.5 volts. When the output amp IC is bad one or more of the speaker leads will measure much less than 6.5 volts or much more than 7.5 volts.
If you have decent soldering skills this is an easy job to complete.

The part number for the amp IC is TA8273H
The easiest place to find it would be at a service center for electronics. If they don't have it they can order it for you from one of their distributors. Most service centers will do this for you. The one I work at does.

You will need to take the radio completely apart, the amp IC is the part that is screwed right up against the big heat sink on the back of the radio
.
If the amp IC is good and the electronic volume IC is bad, you will need to have excellent soldering skills to replace it. It is a surfaced mounted IC called a flat pack with 44 pins on it spread out around the 4 sides of the IC.

Do not try to replace this if you have no experience in replacing surface mounted flat packs, you will most likely damage the circuit board and make the radio un-fixable.

The part number for the electronic volume IC is TDA7411.

Without having the radio in front of me to do more troubleshooting, this is the best I can tell you.
Since you have checked all the wiring and and disconnecting the speakers did not help you will need some expert troubleshooting to find the problem.

Repair shops would normally charge about $100 to $120 to replace the amp IC and close to the same for the electronic volume IC.

I hope this helps you to figure out the problem, or to at least make an informed decision about getting it repaired.
If you need any more help feel free to ask, and a nice rating would be really appreciated if this was helpful to you.
Have a great day :)
Dave
P.S. I like your speakers, you picked some good ones

Chevy stock speakers are 8 ohm. You should change out the stock speakers. Or at least dissconnect the back speakers and see if cd player still overloads and shuts off.

Car deck turned too loud and shut off


The deck might be damaged. In order to accommodate that kind of layout, there should be a cross over, and a separate 2 channel amplifier for the subs. Without that it's easy to fry the deck!

I need the wiring dia. for alpine 8020


If the alpine 8020 is a deck(head unit) the wire diagram is as followed:

Red: Accessory
Yellow: Constant Power
Black: Ground
Orange to orange/white is a illumination or dimmer wire.
White: front left speakers
Grey: front left (white black and so on usually the negative on the speaker connections)
Purple rear left (purple black = neg)
Green: Rear Right
And if a video deck(light green is park brake)
(which is usually just a ground) so legally it needs to be on your park brake but can be grounded to make it work.

Speakers? (Terminals larger one is positive, smaller one is negative) Place capacitors on if needed to filter out and clear up bass

Hope this helps couldn't look uo what a alpine 8020 was..

I'm not getting the correct output from my door speaker only on the left side. was told it is my alpine deck (one of the channels went out)


Definitely possible. To make sure it's not your speakers switch the wiring for them. Basically change it so the side that is working now is connected to the speaker that is not working. If it works then it is your Deck.

Equipment not turning on!???


Have you tried checking the remote wire yet? Because it could very possibly be that. Without a remote wire hooked up, you cannot get any power. Try that and see if it works.

Alpine type-r 2ohm dual voice coil help


try reconnecting your rca's from the deck to the amp when finished wire one speaker positive to positive on left channel and negative to negative on right channel then connect the 1st subwoofer. if all power and sound is fine and working turn off power to amp and connect negative terminal of 1st sub to positive on 2nd sub and positive from first sub to negative on second crossing the wires runs the speakers in series another way to try is parralel the speakers wiring by connecting positive left channel output of amp to positive on 1st sub same with the negative then splice positive to positive on second sub and same with negative.

Alpine car cd player has no volume


It's possible that you have a shorted speaker wire. If one of the speaker wires is pinched, grounded or shorted it will cause the deck's internal amplifier to shut down. The easiest way to check is with a multimeter's resistance function. Remove the CD player and unplug it. Set your multimeter for "resistance" or "continuity". Attach the black probe to chassis ground; you can use the black ground wire in the deck's harness, clean dash metal, or the outer ring of your cigarette lighter. Use the red probe to test each of the speaker outputs in the harness: white, gray, green and violet. If you find a speaker wire that shows any continuity with chassis ground, then that's the cause of the problem. A speaker with a damaged voice coil may also cause the deck to shut down. To test this, probe the positive and negative leads of each speaker and test the resistance between them. For example, to test the left front speaker you'd put the red probe on the white wire and the black probe on the white/black wire. Each speaker should read a minimum of 3 ohms of resistance. If you get a lower reading then it might be causing your problem. If you don't find a problem with any of the speaker wires, then chances are the deck's internal amplifier has failed.
