I am building a box for SPL in my Escort.The box will hold 2 Jensen XS1010's and be powered by a Dual 460 watt amp.The box measures 24x36x12 and the port is 6.5x4.5x12,the braces are in such a position to prevent standing waves and act as kind of a guide for the air to the port.Does anybody see any problems,besides using Jensen and Dual???PS The subs and amp will eventually be replace with DD3510's and an Audiobahn2300HC.
