whats up guys, i found this site from a google search for fi subs.. I'm looking for the best boom for my truck. I drive a 2002 GMC sierra single cab. I have an alpine 9813 head unit, MB Quart component speakers in the doors n b pillar and a 500 watt Orion amp. I had two 12 inch PBX subs in a sealed box powered by a sony Xplod 1000 watt amp. it bumped pretty nice but I didn't like that it couldn't really be heard outside of the truck so i sold it.. I listen to rap about 95% of the time so I like earth shaking bass that knocks pictures off the wall if I'm outside your house. I don't want to cut into the bed though.. I wanted two 12's again but i was told not to have my heart set on 2 speakers because you can get better results with a single sub with the right set up.. Anyone have any suggestions? thanks in advance -Joel
