Hence the reason why I said blow-thru. The enclosure is in the bed of the truck, not in the back seat. iwork construction and need all the bed space i can get. i guess i just wanted to know if anyone sold a slim 12 that would give alot of bass. or if there were better 8s i could run in the space i have, better than the REs i have now. i have plenty of amp just need subs that bump hard in the limited space im working with
