These are 1/4" thick acrylic rings with special .25" LED lights wrapped around the inside to really enhance your install. The plastic is a special white plastic that hides the bulb and diffuses the light for a SUPER GLOW!
The LEDs are taped to the inside of the ring facing outward. The wires will end up on the inside of your box, you will need to route them out of the box to a controller. I have seen them installed on "inverted" subs. If you do this you'll need to make sure to tuck the wires in away from the moving surround of the sub.
Yes- These are expensive. The high quality mini RGB strips are quite spendy, acrylic isn't cheep, they are shipped in with a wood insert to keep from breaking during shipping. This all adds up. However the lighting effect produced by our combination of white plastic and super bright LEDs is UNPARALLED by any other LED ring you can find. Period.
