Installing the hifonics BRX 2400.1 and a single SA-15 in my 04 Pontiac Bonneville SLE. Box designed by CSCStang and is 3.6 cubes net tuned to 34 Hz. Pics coming as they happen!
Doing the last bit of screwin an Gluein on the box (port, front wall and top) and cutting the hole for the sub. Will carpet eventually, but I'm just trying to get running right now.
