I currently have JL Audio 6.5in ZR Components and don't care for the sound they produce. At lower volumes the vocals are quiet and the midbass over powers them but at high volumes they get loud but sound harsh. I have a 450/4 powering them with an addition pair of XR Tweeters in the A-Pillars in a Cadillac Escalade. The Head Unit is a Kenwood DDX8017.
What would be some better components to upgrade to? I considered the Boston Z6 and some Focal speakers.
