So, I have a 2018 Mazda 6 Grand Touring Reserve with the Bose Centerpoint 11 speaker system. Here's what I know about the system so far:
- 2 directional tweeters by the mirrors
- 2 2-3/4" mids (not confirmed, but have read that Mazda switched to 2.75" from 3.5" mids in 2018) in the dash corners, center speaker in dash as well
- 6.5" mid-bass/subs in the doors (size unconfirmed, have read that they may be 8"), same in rear doors
- 2 2-3/4" or 3.5" in rear deck
- Amp under passenger seat. Not sure if h/u is full-range speaker-level or low-level output, as I haven't been able to confirm either. I guess that makes a difference in component selection.
It's not a bad system at all, and there are quite a few things that I like about it. It's certainly better than most GM and Nissan Bose systems that I remember from doing audio professionally years ago.
The staging isn't bad, the mid-bass is acceptable with the windows up or slightly cracked even at highway speeds. The sound overall is fairly flat and pretty balanced, which surprised me with the mid-range speakers firing straight into windshield. I don't notice much frequency cancellation in the front stage, but I'm sure a meter would tell otherwise.
With that out of the way, there are some things that I dislike and would love to remedy:
First, it needs a sub. I'm thinking single 10" or 12", moderately powered.
Second, I'm lacking depth (or fullness maybe) and clarity in the mid-range. I'm not sure how to describe it. It's like when I'm listening to something like Tool, the guitar distortion doesn't isn't replicated in it's full range. It's just a single tone that changes with the notes. Sorry, this is really difficult to describe...
Third, a tweeter upgrade is a must. HF is just lacking, and what's there is sharp and unnatural sounding.
My goal is to improve these areas with as little change or disruption to the interior environment and trunk as possible. Here's what I'm thinking:
- Morel 254's in the dash (open to recommendations)
- No clue what type of tweeters I'm looking for (VERY open to recommendations)
- Either a DSP/amp combo (I've been checking out the Alpine and AudioControl units) to power the mids/tweeters and sub and leave the mid-bass door speakers and center running off the Bose amp OR
- DSP/amp combo or DSP with separate amps and eliminate the Bose amp altogether (this is certainly an option with some of the modern 8-10/12 channel DSP option these days.
- Likely won't replace the door speakers or rear deck speakers, but I do want front and rear stage, although my listening is heavily front-biased. Sub will be a removable spare tire unit, though not sure if I'm going to buy one of the powered units on the market or build my own enclosure. I definitely want that signal coming from the DSP and not from Bose amp.
I won't have the ability to fully tune a DSP in the depth and detail that a lot of guys here do. I also don't really want to go down in a rabbit hole with this and end thousands of dollars into by the time I'm done. I just want a rich, warm, balanced sound.
Am I looking in the wrong direction and what would be recommended?
