[QUOTE="Buck, post: 8771196, member: 591582"] Massive Audio Hippo XL 122R (3000w RMS, 4" VC, 12" Sub) series 6th order bandpass going in the trunk of car and blowing through the rear deck. This one took me a little while. Made the front port removable through the window hole that the sub mounts through, that you access through the removable window on the back of the series 6th order bandpass rear deck blowthrough box, lol. This whole box can be slid in and out of the trunk with the front/top port removed. Laying this out for a powerful sub with a high Fs like this Hippo is difficult, because the ports have to be fairly big. 3000w RMS 12's move a lot of air, naturally.
