has anyone paid someone to make a custom box for 1 or 2 subs, or has anyone built one?

how much does it cost? any help on this issue is greatly appreciated. if you know anything let me know, i have 1 or 2 subs coming but i dont want an ugly single box, dont have room for a duel and dont want to spent 3-$400 on a custom box

 

I made this enclosure to hold a dvc Kicker. I first cut the pieces then assembled them inside the space. The enclosure uses the metal of the car for the top and bottom, so it weighs a little less.

 

I rented a hole saw from Lowes ($0) to make a hole for the 2" pvc port. The port is 12" long and fires toward the driver's side, just in front of the rear STB.

 

how does it sound? does it rattle anything? is your woofer an open air type or no? what the purpose for the tube? would or does it sound bad when the tube is closed? what type of wood do you use and do you really have to follow all the specs for box space?

 

It sounds awesome, especially for an 8" sub! Most people that hear it think I have a 10 or 12.

No rattles at all. I used Great Stuff foam and silicone caulk to seal everything. I used small 90 degree metal brackets to secure the 3/4" MDF in place.

The woofer is not open air, it's a dual voice coil that can be used in sealed, ported (that's what I have), or bandpass enclosures. I have approx. 220 watts on each voice coil.

The tube allows air to escape the enclosure and bounce off the interior of the car. There is a specific name for this phenomenon, but basically it produces more bass than a sealed enclosure. If you cover the tube there isn't as much bass, but I can control the bass level with my head unit.

The first box I built was made to pass through the opening...



...but it wasn't enough air space and didn't sound good at all. My current enclosure is bigger plus the port is farther away from me. So yes I think following specs for building boxes does make a difference.
