SQ
Sound Quality in a car stereo competition. It is quite different from an SPL competition or dB drags. In a sound quality meet, the sonic accuracy is what is being measured and can be quite subjective by the judging staff. Rather than who can hit the loudest note, it is more of how clean can this system play and reproduce music.
No SPL for me, you gotta have sponsors n'shit for dat yo. I gots no Benjamins so I'm goin strickly SQ, dawg!
