I recently had the opportunity to replace the old wore out factory woofer in the Yukon (non Bose system) After several phone calls I found out there are NO compatible speaker/woofer replacements for this vehicle. So with help from the guys at Crutchfield (crutchfield.com), I was able to purchase the Pioneer TS-SW2002D2 8" flat woofer - Shallow-mount 8" subwoofer with dual 2-ohm voice coils as well as the Kenwood KFC-1665S 6-1/2" 2-Way Speakers for the doors.

The fun began when I removed the woofer housing box, removed the factory woofer from the housing box, and then tried to install the new Pioneer woofer.

The Pioneer woofer was roughly 1/8 inch bigger than the old GMC speaker and would not sit in the same recessed cavity as the old woofer that provided a flush installation with the box:

OLD see below

NEW see below

Options:
1. Cut around the plastic box housing to allow the installation of the Pioneer woofer – too much work and it would create a weak foundation to secure the new woofer.
2. Install the Pioneer woofer on top of the housing box. This approach will extend the woofer on top of the housing box. Also, with this installation approach I found there was approximately 1 inch between the woofer and the rear panel plastic cover – no contact.
a. ISSUE: how do I fill in the cavity/gap to secure the Pioneer woofer installation and make sure no air / sound flows out between the new woofer and the housing box.
b. APPROACH: there are several ways to solve this problem including cutting a circular piece of wood or plastic – this to was too much work
c. Take the woofer housing box and your new Pioneer woofer to your local sound system installer – estimate $75 to $85 to retrofit the woofer housing box for the new Pioneer woofer. Not the solution I was looking for.
3. SOLUTION: 5/8 inch Vinyl Hose. Went to Home Depot and purchase this hose - $5, cut hose to fit. Glued the hose to the housing box. Installed the Pioneer woofer. Actually, when you secure the woofer to the housing box, by default, the hose will be locked into place.

The Sound is Excellent!
Finally, I did not have to change any wiring scheme – just attached the wire (red/back) to the new woofer.

Looks great, and a great idea! I'm curious as to how well this sounds with the factory amp. Please post an update and let us know. I'm going to be installing my subs this weekend, but I'm still undecided if I'm going to do anything with the factory sub.

New sub install

Hello guys,... I am installing a new sub and amp tomorrow. Any helpful insight?

I just replaced all of my factory door speakers with Kenwoods also, great sound! Someone removed my factory sub, so I just installed the Kicker hideaway sub under the second row of seats.

I just replaced my sub (foam was pretty much gone) w/ an 8" Kicker and it too had slightly larger diameter despite the fact that Sonix said it was a fit. IMO the absolute best solution is to rout out the inside of the hole w/ a straight bit. I was concerned how the hard plastic would rout but it was a breeze. I just went around and around until the speaker would go in.

Sounds much better even w/ the factory head. It actually has a bit of thump! I'm in the process of replacing the fronts w/ Rockford Primes and I look forward to hearing how it then sounds. The OEM sound does seem heavily slanted toward the high end.

Sorry I missed your request this weekend. Hope your install was a success. As far as the factory amp....works fine for me.

Kicker Sub

HI Guys,

So I went to install a new amp and the Sub. I pulled out the old sub first, and went to install the new one. I purchased a kicker 8". The diameter of the sub is fine, but the depth is too long!!! :( I was assured that it would fit... ugh! So I decided to go ahead and install the amp and wire everything up so that all I would have to do is install the sub and be done with it. After mounting the amp under the back seat, I looked for a good route to run the power wire from the battery. More frustrating!
Any suggestions on where to run the power through the firewall???

I finally gave up and installed the backup camera :) Only thing left to do is find the Reverse Gear cord so that it will come on automatically when I put it in reverse gear. The 2 cords that were suggested online were not the correct ones.
