Hello I need help I bought a 2020Denali Ultimate W/ Bose and I don't like the quality of sound. I bought Utopia a set of 3- way W M's. While doing my research on building my system and surfing the net I found out about Sounds good so I ordered A package that Includes full 4 door sound treatment, A Masconi 8 Ch Pro w/ DSP, Harness, Amp Rack, another pair of Utopia W M's for the front doors. I also ordered all of the block off plates and speaker adapters. I will use the 6" that I already purchased in the rear doors and I already had a JL HD 750 Marine Amp that I will use for a JL Stealth box that is also on order. The Problem that I now have is where to mount the 3.5 W M's and Tweeter. I can do some fabrication and put them in the dashboard next to each other but now I read that it may make the midrange sound dead. I can get those funny looking Utopia Pods and mount them over top of each other with the tweets in the sail panel and the Mids on the A Pillar. I wanted it all to look as stock as possible. Do you think that I could compensate for the dash mount option with the DSP? I also noticed that under the factory grille that the factory speaker is tilted away from the windshield.
In the meantime, I have ordered another set of a Pillars and Speaker covers from GMC maybe I'll try my hand at fabricating the pillars to have the mid and tweets on the same axis. While I wait for the rest of my equipment m from SGS to be delivered. Any Suggestions?

BTW, If I had known about all of the problems that the BOSE system causes I would have bought a Ram or F-150.
Hopefully NAV will quickly release it's ZEN AVB GM soon

Check out the build logs.
several GM guys have done nearly exactly what you intend to do

Since you have the new truck with removable grilles, I would go dash pods. Reach out to Vanguard Automotive Design. Nick designed and built the dash pods for @RickWilson and I believe Nick has the files saved to build a set without having the vehicle on hand. Plus he’s a Focal dealer so he will have dimensions for those speakers. MTI and SGS will also do pillars and send them to you if you want to go that route
