I did a speaker upgrade on my 07 Sierra shortly after I bought it. That was one of the best things I did. Nothing fancy just better stuff than worn out OEM.
Looks great!

I hadn't planned on it, but I noticed the rear speakers were muddy at best, blown at worst. The fronts still sounded good but I wanted to make sure it was balanced. We have some long road trips planned for this fall so I figured it'd make sense to have decent quality audio for the road. The only "downside" I'm seeing so far is that these new speakers want a little more power - just means I have to turn the stereo up a little more. Not really an issue.

I was impressed with how the paint cleaned up too - 17 year old GM's don't always have the best paint quality but what isn't chipped off shined nicely!

You can get the OEM Bose speakers on Amazon fairly cheap.
I posted the part numbers in my build thread.

So steering wheel controls work with the interface unit? I have one of those from a parts truck I want to use in my 2003 2500HD. I'm just addicted to the volume controls on the wheel. I love it. Touchscreen with nav is awesome too, always using nav in the truck.

What Hatzie said is the pre-requisite. But yeah, if your truck already has functional steering wheel controls, the adapter module retains all of that with supported aftermarket head units. My steering wheel controls still work because of the interface module.

I assumed "I have one of those" he was referencing was the UK3 steering wheel but re-reading his post it could mean the radio interface module.

Yea I guess it was confusing the way I said it. My truck came with the steering wheel controls and they function. I got the same interface module from one of my parts trucks with all the wiring.
