what do you mean by unloading and what is ss. im not sure where your going with it.

Not 100 percent sure, but your box only has ~10 sq.in. of port per cu.ft. Fi recommends 12-15, and it seems to me like the larger end of the spectrum would be better for moving air... no my new box has i think 90. what did ou mean by it seems to me like the larger end of the spectrum would be better for moving air...

http://youtube.com/watch?v=fU3nZ-l4vxg just curious my old setup was a 3.5 cubed box with 36" of port. the port was on the right of the box 2"x18" it was narrow. anyways my sub was in the middle both facing forward. it was loud it got really low and moved alot of air. the link above is my new setup. the lows dont really move alot of air like the old. is it because of having to ports. or is the box design not right. the only difference of the new and the old is the new hits highs very good it hurts your ears very badly. why do some people put there subs on one end of the box with the port at the other does that make it louder. i need help with a better box i think. i want to move alot of air but if it means my dbs will go down i dont know. does anyone have a good box design to get alot of air movement and bass.

hi there just bought a fully loaded 15" btl. i used my original box that my audiopipe txxa-15bl was in. the box is 3.5"cu with 36 sq inches of port 2X18. the box is 3.5 before i put the btl in it so its actually less then that. i think the box is to small its in a 98 civic sedan. my wires are 4 guage i know i need to upgrade and a new battery and new alt. but was wondering if i could get a box design ffor maybe 4.5 or even 5 cubes design if anyone had it for this sub. another thing what is a good line driver.
