subwoofer i should get? Also how many? I was originally going to get a new exhaust to make it sound better, but then decided not to, and now I'm wondering what brand and type of subwoofer i should get. (My friend recommended kicker as a good brand.) Also WHAT SZIE AND HOW MANY subwoofer(s)? (My friend recommended two 10 in. speakers) LASTLY i listen to mostly rock, (any kind of rock mostly) and some rap, that's why my friend said to get two 10 in. subs... so im just telling you what music i listen to, incase that changes the size and how many sub(s) i get.
