I had a new box built for my Sanger V215. I've been running two JBL GTi w10's all summer powered by an Exile 2500.1 and liked it but one of the subs was in a compromised location in the passenger compartment and the other was in the prefered under dash location. I wanted to achieve the same volume and sound quality as when the compartment was open so I decided to pinch them under the dash. I had a guy that works with me and a good fabricator build me a custom set up. He's very creative so I pretty much gave him a green light to come up with something fun and cool. I wanted an industrial feel to it and lighting. Here is some of the build pics and the finished product:
Its a down firing sealed enclosure which I was worried about but I love the sound, plenty loud and super clean.
Here is is before the plexy went in. He built it to 1.8 cubic feet after the subs displacement, It's lined with diamond plate that he cut out with a plasma cutter then glued and screwed in place. He painted the outer edge of the plxe to cover the raw edge:
These subs have the positive and negative terminals on the same side so he was able to run a cable through the box to lugs he built on the outside:
Here it is with the plexi on and the trim piece in place which was covered in black vinyl and allowed for ample venting:
Here are a few with the seat base and seat in place. He had to modify the seat base and a couple spots under the dash to accomidate the width of the box:
You can see the seat base is not yet trimed out. We're going to use a piece of black trim to finish off the edge and he's wanting to black out the plexi (think tail lights) which I'm not sure I want so your opinions on that are welcomed. His thought is that it will be less noticable when you look in the boat. All in all I like it a lot and again am very happy with the sound quality and resonance. I was concerened with the down firing not equating to the one sub under dash and the other in the compartment when it was open but these definitly exceeds that. As did the cost!!!
