I bought premium speakers before and I was using a Kenwood mp3 unit 50 X 4.
I just upgraded to a JVC 50 X 4 DVD unit (no screen) and I'm not happy with the sound.
It's hard to describe, but the songs sound "plain". Not enough bass and weak.
Guess it feels sort of like playing a 128kb mp3 Vs a 320 quaility one.
Re-wiring is next!
Thanks guys!
