Car is a 2012 chrysler 300. Amp is an Orion xtrpro 1000d so need final ohm load to be 1 ohm. I have about 4 ft3 gross total or 1.6-1.7 ft3 ported for each 12. Want to tune the box around 30, looking for nice SQL. Not sure on box design either, thinking maybe firing and port towards cabin and sealmoff trunk. Help is appreciated!
