Some will agree with me that sometimes it does make a difference on which way you have the sub faced. Whether you have it faced rite up against the back of the trunk or the subs are pulled all the way back towards the seats. Bass can resonate differently off of its environment. For example my girlfriends jeep had a soft top system sounded alright, she put the hard top on bass resonates more in the enclosed area and sounds alot more detailed. This has always just my personal opinion. Best of luck finding a box though, I wish JL still made the stealth box. There comes a time when you value the trunk space in your daily driver.
