Or maybe heavy is the wrong word but it just feels like some songs have the effect of making my head feel like it is underwater. It's very song dependant so the adjustments don't help for any longer than 1 song. Anyway, mostly just curious if anyone else feels this way. Additionally, if you feel that it is more of a speaker thing or more of just how the car sounds. And by how the car sounds, I'm referring more so to the acoustics of the car. I've done some light modifications that should help sound. Insulation of the doors and trunk area, for example. Just curious what your thoughts are. If you feel this way too and or if you've found a solution in upgrading the stereo, etc.
