Alpine stereo car deck installed in place of factory Bose with

Factory amp 93 audi stereo system pops through speakers when a sourc input is chosen or a new song plays or key off & key on.plays well once started .pops every song change.So far I am told that the factory amp needs to be bypassed.I have no interest in doing that. The remote wire is hooked to provide power to the car amp.Otherwise no sound at all.The internal amp of the Alpine deck is turned off & the speakers are powered by the RCA jacks on the alpine deck.Audi speakers are all amplified from factory.Plus audi has front & rear amps in the car.It would be an active Bose system.Not a passive one.

    Thank you for replying to my audi stereo popping noise.In spite of being told that my only hope was to replace the factory amp ,I still wasn't prepared to do that.As a result ,I continued looking for an alternate solution.It was suggested to me by a tech at PAC in Calif that I should install a ground loop eliminator in series with the stereo RCA jacks of the head unit.I purchased 2 & installed them & problem instantly solved.5 minutes work.Factory amp is plenty good enough for me in this case.
    Thanks for replying  anyway.

What you have been told is correct, these proprietary systems are great for the manufacturer, but when they start to have issues (and they will) they leave you 2 options: pay through the nose to stay original or replace the amps with new ones....the upside of this is aftermarket amps are soooo mugh better than stock that it is lauhgable.

    Outstanding, those ground loop capacitors should last awhile, if problems come back remove ground loop and touch rca ends together to dischare then reinstall.

My car stereo was stole they cut the factory wiring harness from the durango i need to know the color codes of the wires please

That's hard to answer cause it depends on how far back on the wire harness they cut. Plus if you have a Bose system or not. I would highly suggest to take it into a stereo install shop to at least check it out but maybe install the new stereo.

There is a wiring color code that all vehicles use but if the wires have been cut to far back they will be different colors. If you have a factory amp then you will have to rewire for the speakers to bypass it.

I added below the color code. Make sure you disconnect your battery before you start wiring anything.

Please note: You can do major damage to your truck computer and other components if you wire it wrong.

Proceed at your own risk

After installing the alpine CDE 9870 car stereo there was no sound... although the car speakers work.Maybe the audio in the stereo?Can thatbe fixed?

In this situation 8 times out of 10 the problem is not with the radio, it's that there are factory amplifiers. Many cars have them, and most require a little work, or an adapter to get going. Tell me the year, make, and model of the car, and perhaps I can give you more info.

My 93 camaro z28, stereo wiring is all jacked up.i dont have 12v for my memory.the factory wire harness is cut off how do i wire it to my aftermarket stereo

Use A test Light to Locate KEY OFF Power for Memoey, And the Same for KEY ON POWER For Radio Power Lead. there ARE EXTRA of Both @ Fuse BOX. Speakers are Colored Alike In Pairs Of 2 Look for 4 Pair for 4 Channel Set up. OR REWIRE SPEAKERS all together as this is the Most Effective Way to Wire Speakers Anyway. I Hope this Sheds Some Light on your Problem and Helps you Wire it Correctly Feel FREE to REPLY With ANY QUESTIONS.
