update: i got rid of all that factory sound deadening material from my trunk and then i put dynamat on in my trunk, BIG inprovement on bass and way less rattle outside of car. then i cut a hole through the rear deck and bought a sealed box that holds 1 12 and a Sony Xplod 2200-GTX amp. i bridged the amp and wired my Kicker CompVR sub in series so the amp got a 4 ohm load (the sub is dual 2 ohm) and gave the sub 500 rms! Let me tell ya the bass is a lot LOUDER and CLEARER than it was before! i played Late Night Tip by Three 6 Mafia to test out the sub; and the bass was so ****in loud the bass was rattling my house windows(my car was in the driveway) any i guess my neighbor heard the bass and ran outside from his house to tell me to turn it down or he was goin' to call the cops. thanks for all the advice guys. //content.invisioncic.com/y282845/emoticons/thumbsupwink.gif.129404938effda6ad9cca39e7f4b58a3.gif this is the best setup i've ever had! i love it! //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif
