I purchased a new Mazda Select Sport a few months ago. I love the car but the car audio system is one of the worst I have heard. I am wondering if anyone here has done an upgrade on a 2024 model that doesn't have the Bose system? I checked Crutchfield and they show the only possible speaker fit would be 4" coaxials in front and rear. I have a 5 channel amp left over from my previous car so I am thinking of going with Focal Access coaxials and a sub in the trunk. I would love some feedback.
