Spl Or Sq what do u choose 4 hifi sound systems

[err 0]

SPL = Sound pressure levelSQ = Sound qualityif u are music maniac, u must know that.which one do u like? why do u like it? descripe here..btw, for myself.. i like SQ than SPL coz i like listening the music much more than the player it self.many cars audio contest now, usually using SPL category. but i thing they just need to win that contest so they install the crazy SPL hifi sound systems. after that.. finish. they just play for awhile. then bored. replace to anoher crazy spl. again and again.
