01B4000 Posted July 10, 2013 Report Share Posted July 10, 2013 I designed a box for a Soundqubed HDC3 18 that will fit in the back of my Mazda pick up. It will be running off a Cadence 2500.1 (1200rms) with stock electrical but will be doing the big 3 very soon. Opinions?

Brandonbkd Posted July 12, 2013 Report Share Posted July 12, 2013 You might want to add a 2nd layer of mdf to the baffle because that'll be pretty strenuous having that 18 on just a single layer FI BL18 Build Log: CLICK HERE!! 2003 Explorer Sport: FI BL18 SoundQubed 2200 at 0.7ohm Pioneer DEH-2500UI Pioneer 6 x 8s Rockford Fosgate 6 x 9s 5 ft^3 box at 35hz Lots of Mega Mat Link to comment Share on other sites More sharing options...
big dee Posted July 12, 2013 Report Share Posted July 12, 2013 Is this going in the can or bed? I know most trucks beds are to shallow for a 18 to be done for blowthru. Box will be higher than the top of the bed . Unless you got a camper or something along that line Link to comment Share on other sites More sharing options...
big dee Posted July 12, 2013 Report Share Posted July 12, 2013 An if your doing this in a excab lol get ready for serious rattling from the roof. I like to sound deadin the roof then use expanding foam betwin the head liner an roof . In my trucks this works perfect. Only bad thing is the head liner is trashed if you have to pull it back down again. And also go slow or it will bulged out . Use the medium expanding foam for windows and doors an it will help on swelling out Link to comment Share on other sites More sharing options...

BASS14 Posted July 13, 2013 Report Share Posted July 13, 2013 looks good, I would move the port to the othersside of the box tho, so its behind the driver seat. I own a ranger and have done a set up just like this a few years ago. single DC LVL5 18 and a team cactus sounds 5k.

john253a Posted July 14, 2013 Report Share Posted July 14, 2013 You could so with a bit more port, but you deff need to move the sub from the middle, it's too close to the port Moving it closer to side will also help with flex in the box, But you really need to double that box up, If you don't have the space for another 3/4" use 1/2" anything is better the nothing, Link to comment Share on other sites More sharing options...
