I'm looking to make a box for 97 Maxima to hold (2) Premier TS W3K4spl's. I want a single box, ported with a dual chamber, and I want to know what is the best specs for a box like this to make them bump. I'm going to power them with a HiFonics Bxi2006D at 1 Ohm and send 1000Watts to each sub. I want to first make sure the box fits, and slides all the way back in the trunk. All responses appreciated.
