ProBox has become the nation's leader in automobile subwoofer enclosures, and the people's choice for the ultimate experience in quality and sound. ProBox holds the title for '91-'92 U.S.A.C. world champion, unlimited spl. With over 20 years of sound design behind us, it's obvious ProBox comes out in the lead.

The ProBox enclosure is made from HDF (high density fiberboard) with the computer-controlled precision of CNC routers. We have created a special style of assembly that we call "The Stack". The HDF is cut into layers that conform to the contours of the floor of the truck. The frame of the box is then glued and nailed together one layer at a time. Once assembled, the entire enclosure is sanded to a seamless finish, and our special ProBox Armor Coat is applied.

To achieve maximum performance, we recommend using an amp with "Bass Boost" and a 12 to 18 dB boost at 45 Hz with the crossover point at 90 Hz and down. With gains set correctly and "Bass Boost" turned on, your ProBox will deliver an awesome performance you'll want to show off to all your friends.

All of our ProBoxes are made with pride in the USA, and come with a one year warranty.
