I wouldn't do KO's if you drive in snow a lot. They ball up with snow and don't clean out but I've heard people claim this is what they're supposed to do (and then I pull them out). I've had better non snow rated GoodYears. However I would get KO's if you live in the south because the seem soft with long lasting tread.

Update on this one - upon making fun of the pathetic Bose system at a dealer, a friendly parts guy told me he had the GM 8" Kicker sub and let me listen to it. I thought it was good enough and had some points on my card plus 20% off so I did it. Initially I thought it was ok after install but still kind of weak and it started to get a little better after breaking in a bit. I decided to take the amp to see if it was replaceable. There was a little rubber plug on the back and when removed revealed 6 DIP switches. I searched online and found 3 of them were gain but only 1 of 3 was "on". I flipped the 2nd one "on" and wow did that wake it up. Now it's much better than I expected. I might think about replacing door speakers now. Or getting the inputs from the Bose sub input instead of a side speaker like it they install it.

What's the verdict on the Diamond Audio subwoofer after a year? I was thinking Kicker from the dealer but if I can do this for less than half the price my wife won't be as mad at me

Thanks redwngr. I should have the UQA 7 speaker option. If a richbass woofer exists, it's not hooked up or very weak.

Well that's disappointing. The other Bose systems have been always just good enough I didn't bother to upgrade. I found a few options on other forums to investigate. I'm not wanting to take up storage space under by back seat with a big sub box.

I just bought a 25 Sierra SLT. Do these still have the sub in the center console with the Bose audio system? I can't detect noise or vibes in the center leaving me to think it's been cost reduced out or not hooked up. I had a 16 Sierra with the bose that thumped way better. I have a 21 Yukon now currently that sounds a lot better with significantly more thump.

My brother is a GM tech. He thinks it's in the tires and has change several sets and the vibes allegedly went away.
