My install for street class with one 12" woofer (all in the trunk and below the glass).
This is only position of the box and port to fit all of the components (box, one battery, two amps) of the system in a trunk.
KK, nice vid´s by the way.
Hi Nastradamus, did you tried to facing the corner of the trunk with the box. Like Ric does, he did a 158 with a SA 15 D2 on something like 6 K-watt´s

If he buy dual 2 Ohms he can run them on 4 Ohm, or dual 4 Ohm´s on 2 Ohm´s. Than isn´t the 5 K to big.
