Hi,

I'm looking to upgrade my new 2021 Mazda CX-5 6 speakers version (non-Bose).

I was thinking about 6.5" Component at front and 6.5 Coxial/Mid Bass at the rear doors, connected to a 4 Channel Amp and JBL Basspro Hub at the spare tire ( I don't want to lose space at the boot).

Now, it's a bit tricky to know which speakers will fit at the doors as I couldn't find any documentation of depth compatibility for the Mazda CX-5 online. Does anyone know ?

Also, without knowing the exact size can you recommend any setup for a very clear & crisp sound without compromise ? originally I was thinking to go with:

Front Component:JL Audio C2-650C / Hertz Mille MPK 165.3 Pro / Focal PS165 FSE
Rear Coxial: JL Audio C2-650X / Kicker CSC65 / Cervin Wega V465
Amp: JL Audio JD 400/4 / Alpine X-A70F / Focal Impulse 4.320
Sub: JBL Bass Pro HUB 11"

Would love any input you guys have,

Thanks
Leo

Looks like it's time to open the door grab your trusty tape measure and do some investigation/planning.  

Being a Mazda fan, from experience, I am going to suggest you add some sound deadening to the install too.
