-i like to listen to my music pretty loud, especially when i have all the windows rolled down i like to crank it up as much as my speakers allow me before SQ becomes an issue especially with my stock door speakers(which i plan to upgrade as well). But i generally listen to a variety of rap, Hip hop, dubstep, and house music.
-for subwoofers I'm looking for a sub thats loud and clean that will put a little more 'oomph' in the bass compared to the two i have now(two Alpine type-e's in a sealed box). I don't need a sub thats solely SPL and will just gonna rattle the heck out of my car if you know what i mean. But, Im looking for a sub that produces good SPL and also great SQ. one thing i like is some good SQ, I'm not looking for a sub thats just gonna blow my brains out and shake all my windows and doors, but definitely one that will still pound (more than two i have now) and produce good clear audio.
