Anyone know what a good box size is for 1 JL 13w3v3? It is installed in a 2005 ford explorer in a ported box that is close to 4 cubic feet.
JL recommends a box smaller than 3.5 cubic foot. I am having problems with the sub loosing control when turned up at a louder volume. I am currently using a Alpine MRP 650 (400watts) and the sub is a 500 watt. Does anyone have any suggestions on what is going on. The company i bought it from says the box is tuned at 34hz. JL says no more than 27hz.
