I really wat to get a little extra bass on top of the Hk system in my 05 MCS. I looked all over here and all over YouTube for ideas, but I have a problem. My 05 MCS is supercharged. Which means that because the supercharger takes up too much room in the egine compartment, they had to move the battery to the rear where the spare tire would be. I have seen guys building bad *** boxes on the floor of the boot, but they also dot have the battery in the rear. I see that they are selling the boxes for in upwards of 600 dollars online, but would rather not pay that much, or possibly build my own. I already have the speakers and the amp (2 JL Audio 12's and a Rockford Fosgate Punch 300 amp.) Just need to find out about an enclosure for at least one of my 12's and the amp. I'm currently in Tacoma, Washington and if there is anyone local that could advise me or maybe has one for sale... Any help would be greatly appreciated. Thanks guys!

Motor On!
