New Owner - '06 Yukon Denali

[BsYukon]

Throw out any suggestions you may have in general also... trying to dig for info. Also curious about reasonably priced performance mods - and of course gas saving tips I read something about the Blackbear Tune - thoughts? If there's something in particular that I should look into, or consider first? Please share... just learning as much as I can right now.

Another BIG thanks!!

Back - and need some help!

NEED SOME HELP HERE! Figured I'd try replying instead of starting a new thread...

Held off replacing the head unit to have MP3/Phone options until, well today. I bought the following from Crutchfield and had a local shop do the install.

JVC Double Din:

Metra VT-GMOS-04 Factory Integration Adapter: (to keep chimes and OnStar):

Axxess ASWC-1 (to keep steering wheel controls):

I was going to install it myself, but after reading the instructions with the steering wheel controls I decided to have the shop do it. It only took them an hour - would of taken me way longer, so well worth it (I thought).

My problem is - IT SOUNDS WORSE! All speakers are distorting when I turn it up past halfway or so. I NEVER had distortion with the factory head unit. I simply wanted the same quality sound (hoping for a little better actually w/ aftermarket receiver) and Phone/MP3 capabilities. I'm also not sure that the center console sub is working - sounds like all of the bass is coming from the Bose door speakers. I also tried toggling the sub on/off within the receiver menu - there was no difference.

The easy response would be to go back to the shop and have them fix it. To be honest - I'd rather go somewhere else, or figure it out myself. Right now I can't turn the stereo up loud enough to hear with the windows down without the annoying distortion!

Can anyone help??? Anyone have similar experience or problems?

Thanks!!

You need an amp.Most receivers only put out a few watts,barely enough to power the mids and upper range,forget a sub or any bass,that is where you use power.All aftermarket receivers of any quality are meant to be paired with an amplifier(s).The shop should have told you this of course.Not sure what a Denali/Yukon/Tahoe do for factory amp...I am in the market to buy one as I speak(tick- tock!)

Fixed!!

I did some more digging - found another post about the GMOS-04. There's actually a volume adjustment on the GMOS itself. They didn't adjust this when installed - so my guess is the radio was having to push too many watts, causing the speakers to distort. I turned up the volume on the GMOS - made a HUGE difference. Now it sounds great!!!

^ Denali does have a factory amp and sub - which the GMOS-04 supports.
