2022 Yukon Denali Bose subwoofer dump

Hey all,

I ordered a Yukon Denali 5 months ago and it just now arrived - Micro chip shortage. . I am speechless its an amazing truck!

it has a 14 speaker bose system, As I was expecting the bose subwoofer is not even in the ballpark. the rest sound ok, I can hear the speakers fighting to create bass and they just can't. I have a fair bit of experience building and wiring some high-end car audio systems back in the 90s and lots of current experience with audiophile home systems. I know things have changed since the 90s🙂

Originally I was thinking I would find a place to do a simple sub install, but the more I ask around, the less I trust anyone to work on this thing, they just don't seem to know what they are talking about or are familiar with with these new trucks. I found the Bose sub in the back left quarter panel, and I was surprised to see the fuse box right next to it, got me excited thinking that I could mount AND wire the amp right there off of the fuse box, or close by anyway. Thoughts? I have no idea what AWG wire is there but assume I would want at least 8awg. I had visions of having to run a power supply all the way to the battery. I suppose that is still probably ideal but I would prefer not to if I can help it, it sure is a far distance. Also, it appears I can just get an amp with high-level inputs and unplug the bose right there?

I plan to run a small 200-400 watt RMS amp and then build a small ported enclosure for a 10 or 12-inch subwoofer. There really is not much room with the 3rd row up.

Any thoughts or experience with the wiring back there on a 21 or 22 yukon??
