Compact design speaker box port. specifically designed for a Jeep JK overhead speaker box. This will help with the rattle sound you get with big bass from aftermarket speakers and system. It has a hole in the bottom for a 5mm LED for extra light effect. Print two of them and fit them into a 52-54mm hole in the speaker box. They should snap into place for a tight fit, but may require a little glue or double sided tape for a more secure fit.
