buy my box and recarpet it

/thread

on a real note, i'm not familiar with competiting but 8.7cubes may be a tad small after u calculate port/sub/brace displacement.

Subs up, port back.

Do not tune to 50hz unless it's STRICTLY spl vehicle with no daily driving.

38-40hz is the ABSOLUTE MOST you should tune that to.

you could fit more than 8 cubes, its just if you want to stay under the window line.

my box is 8 cubes and is like 1/8th of an inch above the window, but cant really tell.

That enclosure i showed you is roughly 12cubes without any displacement. After calculations, each sub was receiving a little over 4cubes. That enclosure was tuned to 35hz and it did me well while i had that system

you'll spend more tryin to deadened the car than you spent on the system.

no chambers

i guess you can take down your backseat and extend from there, keeping the enclosure at the window line

50hz is way to high
