I Have a nice setup now.. But have no Lows. Mediums and highs are great but I NEED lows. I am trying to decide how I want to do it. I don't think I will get what I want out of the MTX, CLarion, and Q-logic hidden boxes and I don't want to spend that much money for a box (no offense, I did look at them originaly). Anyway, back to my problem. I had one 12" years ago and it hit hard and loud, but the box was huge. I am thinking one 12 or two 10s. I had two ideas for a box so far. Since I use my cargo area quite often I don't want to lose it. But I can sacrifice some space. The first idea was to build and enclosure on the right side that would fit right up against the side panel and go to the height of the bottom of the window. But I am thinking it might need to come out pretty far to get the air space. My other idea was to get a shallow sub or two and build upt the floor 6 or 8 inches and mount the subs flush to the floor maybe facing down so I can still have a nice cargo area? What are some ideas?
