I installed this pioneer subwoofer into the space behind the bucket seat of my 94 Toyota pick up truck. It fit with no problems, though I do need to have the seat about 2-3 inches forward from where it was with its back against the cab wall. This unit has withstood the rigors of four-wheel-drive, and none of the connections/hardware have worn in the slightest in over a year of ownership. The bass response is not as deep as the triangular ported boxes, nor is it particularly strong below 63hz, but this thing slaps for what it is… A small, high-quality/low-cost behind the seat Subwoofer. I wired this to an 800 W pioneer class D amplifier, and it puts out brilliant sound in a small package. I have been satisfied by this product more totally then Sony's comparable equipment, I have purchased in the past. As a mobile DJ/audiophile, I like to spend my money on US-made pioneer equipment because I know they have quality consumer protection, a reliable background, and innovative technology. Sure, it will cost you more than a Pyle, but do you want a pile?

Not good for deep bass in the trunk.

i bought this sub alone no box, for my van to get some extra boom without takin a lot of space. built my own box to sealed specs. i was completely blown away at the sound quality from this flat sub. ive heard a lot of bad things about flat subs. pioneer figured out how to keep the boom without the space. great sub, great price. buy at least 2 of em.
