[QUOTE="keep_hope_alive, post: 7344012, member: 576029"] i've thought about trunk "enclosures" before. i think you'd have to basically line the trunk with MDF, sheet metal will flex and you'll lose output. sealing an enclosure is only half of the work, making it stiff and non-resonant is really important. Dodge Neon sheet metal will never be stiff enough, it will flex and you'll lose output. but you could box out the trunk to obtain the volume you need. do you need rear seats? cuz your best bet would be to remove them and wall off the car. amps could go down where the seat bottoms were. you could fabricate some expanded metal and cover with fabric to make it look like there was a seat and protect/hide the gear. ice shield won't deaden anything but it'll make the car heavier. deadening requires a viscoelastic and elastomeric product that converts vibration into heat. roofing products don't deaden, but they can be used to seal up the rear deck though. and the added mass will be better than nothing at all. you're obviously set on DD-Drive. that's cool. what's your goal with speaker placement? keep in mind that any speakers in the rear deck need to be enclosed or the subs will just blow them out - literally.
