Nice clean bass with a slightly stiffer response. Can handle the rated power well without sounding overloaded. Cabinet design makes install easy and provides the correct air cushion for operation. As all subs go, bass can get muddy when hiding behind or under something that is not acoustically transparent. A good value too.

This sub works nicely in confined spaces, compared to my wife's solobaric it's weak, but that's not what the intent of this product is. The sound is nice and a rich deep bass was added to my car with this and it does not take up very much space at all.

I would recommend this for anyone short on space looking to just add more bass to a system.

If you like good clean bass, then this speaker nails it. It fits nicely in my truck and pounds out good sound.

Pioneer designed this sub & enclosure for those of us with very limited space. I bought one for under the rear seat of my Tundra double cab, and it was a perfect fit. The depth and pressure of the bass was exceptional considering it's a small shallow mount sub with a small amount of air space. The appearance is very basic, but that's not why you buy an under seat sub. The construction is as good as any custom or store bought enclosure, with heavy duty gold plated connections. I'd recommend an amp that meets at least the minimum rms wattage of the sub (200w) to get the full sound this sub is capable of. I give it 4.5 stars, and for the money, it's gonna be hard to find a better value.

This is a decent sub. It plays best facing the rear. I have a sedan and tried it facing front, down and up... but like I said rear facing is best. Better sounding over time. I use an MTX amp to push it. It definitely makes a huge difference from factory. But not going to rock your neighborhood. Good overall. But only if you're tight for space. Otherwise get a regular sub and sealed or ported box.
