Simple... DD9512g in single cab chevy

[imhungnurnot 9]

The box is 2.6 cuft @ 39 Hz with 16 square inches of port per cube. Need to build another so I can reach across the truck to roll down the window.. lol (also i think i will tune the next one around 33 hz)

dont DD's usually perform best tuned higher? seems like 33hz is kinda low for a dd from what the website says
