This is a simple method to make one of those Sweet Sexy Speaker cabinets that you see in all the Car magazines. This method can also be applied to speakers for your home or other mods for your car such as amplifier racks or something as mundane as a cup holder. It can be blended into your interior by colour matching paint or covering it in the same carpet materials as your cars interior. However I went with covering it in cheetah fleece fun fur and hardening it with resin.
The basic construction is to use either MDF or Plywood as a base, hollowed out for a speaker and a skeletal support structure built from the same materials. Fleece is stretched over the support frame and stapled or hot-glued in place. The it is painted “wetted” with polyester resin, sanded smooth and reinforced from inside with fibreglass matte. In the past I have made a translucent version that was backlit from inside. For the speaker rings and supports, I cut ¾” thick lexan into my desired shapes and used a combination of ¼ “ lexan sheeting and woven fiber glass cloth for all the intricate bends and flat panels. I mixed a touch of phosphor into Epoxy resin which I used to wet out the fibreglass. Inside the unit I mounted a black-light neon automotive tube. At night it glowed with an iridescent sheen that was quite spectacular, but with this sort of set up you really can’t use nice boomy speakers as it’s just not rigid enough at higher volumes.
This smaller speaker cabinet demonstrated here is going in my beater pick-up. It’s one of those old Nissan King Cabs with the fold up seats. As I still torture people from time to time by making them sit back there, I wanted a speaker unit that was small, relatively smooth and free of sharp angles. The raised spiked feet elevate it over the hump running down the center of the cab, they also dig into the carpet locking it in place. It was measured so it was held in place by the center console and the back wall. Its Surian eye port looks out over top. the downward facing subwoofer reflects base down and up, really filling the small cab of the truck. Being all smooth in nature, In the event of crash I figured I’d lessen the death trap back there by allowing their heads to collide into something smooth and round instead of a heavy MDF Square box. Ok, in reality it just looks cooler, but I digress. Follow the steps to learn how to make a simple yet sexy speaker cabinet.
