amp doesny have one

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...

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.
