or 2 12s

Massive Audio Hippo XL122 Massive Audio Hippo-122 12" Hippo Series Car Subwoofer (second pick)

Massive Audio SUMMO 124 Massive Audio SUMMO-124 12" Summo (Sumo) Series Subwoofer

How do you intend to direct the port?

Ive got a similar car (2010 crown vic) and i was wondering how you plan to place the box. If your trunk is the same as mine, were you planning on place the box on top of the fuel tank directly below the rear deck? If so send me some pictures and some measurements and i will draw you up some plans. And what are type of bandpass were you looking for? Are you looking for full spl or are you looking for a good musical box that can get loud but will sound good overall?

I also have a 2004 and was looking at doing something exactly like this with 2 8" porting through the rear deck where the 8" factory subwoofer hole is via an 8" aeroport, any plans or ideas?
