Looking for the perfect way to add some quality bass in your car without sacrificing any precious space? Pioneer has the perfect solution for you with their shallow mount subwoofers. By integrating some cutting-edge technology, as well as some industry firsts, Pioneer was ale to make a shallow subwoofer that sounds as good as a full size subwoofer. These subwoofers use a unique Air Suspension system that traps air in between the main cone and the drive cone. That air then acts as a spring and removes the necessity of having a spider to keep the cone aligned. This system allows Pioneer to reduce the mounting depth of the sub without having an effect on the overall sound quality. This design also enables the subwoofer to work with small enclosures that fit snug behind a seat, under a seat, in a trunk, or any place else that space is valuable. The cone of these shallow mounting subwoofers are made with interlaced basalt, a material that only Pioneer is currently using in the car audio industry. The volcanic rock material the subwoofer produce a more natural and deeper sound. No matter what type of car, truck, SUV, van, or other type of vehicle you have, a Pioneer shallow mount subwoofer is the perfect way to add quality bass.

I think anyone who purchases these speakers will love the sound you get from them. I used them to replace the kicker speakers I had in before. They have better sound, louder bass and fit perfect inside my Chevy 2500 4 door truck. The sound is concert quality inside and does not rattle the outside. Great speakers for any selection of music. Will definitely purchase again.

I've had these for a few months and I still can't believe the sound. The bass sounds clean and hits hard too. People always smile when they hear and see how much room my trunk still has. They always say the same thing "I thought those were for trucks". I had a smaller pioneer amp hooked up to the two 12's but finally ordered a kicker 750.1 and it makes these things pound. I will never go back to the full size speakers again

Talk about a nice subwoofer. I just installed a set of these hooked to a Kenwood KAC 9105d amplifier, and man do they bounce. All hooked up in a 06 Silverado in a under the seat down firing box, and I couldnt be happier, highly recommended.

Bought this sub and didn't know what to think but its all i could fit in my 1995 chevy downfire box. I installed it with a JH300 Mtx amplifier and it seriously does hit harder or at least the lows harder than a Kicker Cvr cause that is what i use to have in it but man does it sound good to. Even if i wasn't short on room i would by this sub!

I bought this sub today and i was skeptical about buying it because it was a shallow mount. But wow is all i have to say! Better than my 12 Kicker CVR. Seriously this sub rocks sounds amazing hit lows very well. Rap, Rock, Jazz, Pop, whatever it can handle it very well. BUY this sub! It will amaze you. Im just wondering if my truck can handle it when it breaks in?????
