For my reg cab truck I built as big a sub box as I could fit behind the seat.
It's a 3/4" MDF common chamber wedge shaped box for 2 subs:
- 48" width
- top 4" deep
- bottom 10 1/2" deep
- 18" tall
I modeled it in autocad and the total volume is 2.3 cubes.
It has an recess in it in the center to clear my center console and to make room for an amp (reg cab trucks are very cramped for space).
It has 2 Alpine Type - R 1221d drivers in it wired to a 2 ohm load, driven by a MTX 1501d amp.
It sounds good and solid now but I would like more volume from it and for it to play lower than it does now.
With this small of an enclosure, can I see an improvement in volume by porting it?
The most room for 2 ports external to the box can be:
3" wide x 4" tall x 32"
Will this cause to much port noise?
What should I do ? port it ? get more efficient drivers (e12a's) ?
