bro im telling you.. i have had hdc 3, xfls, 9500s,type rs,ect.. the btl is nasty. tuned to 29 hz..amazin, hits high notes crazy well and murder lows.

if you can squeeze 4.5 - 5 cu, thatll be good but tun between 28-32. i would do aero port side fire with sub forward if your seats fold down

I can slide up to a 7cu box in trunk with sub up. I do plan on haveing custom box made so sub fires into csr.

For daily application what would be better slot port with sub up. Or aero port and sub faceing into car or sub in car port out the side.

i'm halfway done building a box for a Fi 18BL.

square port tuned for 45Hz for SPL.

rectangular port is tuned for ~30Hz for normal use.

Plugs will be made for both and the 45Hz will only be used for comps.

I prefer sub/port firing into car. I do oversized ports with a port reducer for daily & metering....
