2006 Silverado Help Please

Long time member here, dont post much always read. Traded in my s10 for a silverado due to 4x4 needs. After I bought the silverado i dropped in my 2 12" subs with my amp, wired up my song cdx-gt520 and worked like a charm with the wally world chime adaper wire harness thing. After about 2 months, door speakers quit working, pulled it out, rewired it all to what i though was perfect with clamps and tape. and only the left door speaker worked but both piller speakers worked the whole time and was to lazy to pull it back out figureing it was a bad speaker. but in a few days i started the truck and bam all 4 speakers worked. turned it off to go into the store came out and only the 2 piller speakers work now. Im thinking they both work just something wrong with the harness, what do you think? sould i buy another harness from walmart and try that? re wire again? if possible could someone tell me wire colors? i looked online and couldnt find anything. or should i buy new speakers and install? what size will fit?

Thnks for the help

Re: 2006 Silverado Help Please

Radio 12V - Orange (+) - radio harness
Radio Ground - Black/white (-) radio harness
Radio Ignition - class 2 serial data
Factory Amp turn-on - pink(+) - radio harness
Left Front Speaker- tan (+) / grey (-)
Left right speaker- Lt. Green (+) / Drk. Green (-)
Left rear speaker - brown (+) / yellow (-)
right rear speaker - drk. blue (+) / Lt. Blue (-)

is your truck equipped with the factory amplifier / if so, this could very well be the issue,. if this is the case consider bypassing the amplifer .

pull the radio out and using a test speaker connect it directly to the speaker outputs off the radio ,see if the issue occurs, if so , your radios outputs are giving out

if not make sure your factory amplification system is bypassed/ if you dont have factory amplifier check connections etc.

*if equipped with factory amplifier the amp should be under the center console in that vehicle*

let me know what you figure out.

Re: 2006 Silverado Help Please

I kinda had the same problem. Friend has a 06 as well. 2 12's and stock mids and highs. Put in the door chime thing....everything worked perfect....for about 5 months. Everything quit working....the head unit would come on with the truck off....but as soon as you started the truck....the head unit would shut off. I spent days trying to tracking down the problem....NOTHING!! So i bought another door chime thing......same thing...nothing. So what i ended up doing was putting the stock head unit in and running a line out to hook up the amp. works just fine. So i can almost garrentee it's your door chime box.

Re: 2006 Silverado Help Please

I have an 06 2500 Crew and I kept all of the factory equipment becaues it was the Bose system, and just added a couple of subs with the line out adapter on the facotry head unit. Works great for me.

Ive heard a lot of problems like this when people start changing the head units. Something with the way GM routed the warning chimes through the stereo system. I would try replacing the head unit with the factory one and see if that fixes the problem.

Re: 2006 Silverado Help Please

I think your problem is that your shopping at Walmart for stereo equipment
We refuse all harnesses and install kits from there, they are nothing but crap and trouble! For some reason Scoche stamps their name on that crap and yet turns around and makes good decent parts for everybody else. When people come in, hear our prices, buy from Walmart, then come back expecting us to install it and we refuse, they just claim that the Wallie crap is the same stuff that we sell, just cheaper. Dam world economy!

Re: 2006 Silverado Help Please

I used the kit from crutchfield in my 06 chevy van. Should be same wiring and everything as the 1500. Worked like a charm and has had no issues with it. Very well could be the wally world crap adapter. Those things are pricey but I got a good discount on mine at the time because of buying the head unit from them to.
