[QUOTE="sxpimpin, post: 6765003, member: 562076"] Well I picked up a 1986 pontiac parisienne recently from my great grandmother and decided I would do a little sound in it. I picked up my old memphis mojo 2000d amp for power and decided to run 6 hifonics HFI 12's. I did 2 layers of deadener on the lid and a layer on all walls of the trunk. Long story short I've tried subs up port back... LOUD outside, but no bass in cabin.. seriously sounds like a pair of 10s(with alot of flex).. I then tried a small 4th order bp to get the bass firing forward. A tad bit louder but still at least 10db's quieter than I expected. So now im trying to figure out what i need to do. Sale the subs and do something where i can fire subs and port back.. seal around the port completely into the cabin.. ect I just need some help on the system design.. my HD3 15 on 1200 watts would dominate this setup right now..
