I purchased this subwoofer for my 2002 Chevy Tahoe with the non-bose system. I was pleasantly surprised to see that it actually fits without modifying the factory box. You do have to drill new holes for the screws to go in, but the basket fits in the opening, and the magnet does not bottom out in the small enclosure. I am currently running it from the factory amplifier and while it won’t win any SPL contests, it does sound clear and hits the lows very very well. It’s a very accurate subwoofer and downright fantastic when you factor in the price. I posted a video on youtube if you want to see how I did the install. It’s titled 2000-2006 Tahoe Subwoofer Install. I attached a picture too, sorry for how blurry it is.
**Update** I have now been using this subwoofer for a few months and still absolutely love it! it sounds even better than it did when I first installed it. It seems to have warmed up a bit as it broke in. I have also now attached a video that outlines my installation in my 2002 Chevy Tahoe. I hope it’s helpful.
