At 6" deep, this sub will fit behind a lot of seats.
Rockford Fosgate has earned a reputation for building superior subwoofer Enclosures, and their T1S-1X10 Sealed Enclosure exemplifies their expertise. The Sealed Enclosure houses a Power-Series slim line 10" subwoofer that handles up to 500 W RMS, for maximum bass from a minimum of space. The truck style Enclosure is only 6" deep, so it'll fit behind a truck seat and in other tight spaces, while its 1 ohm impedance draws maximum power from your compatible mono amplifier.
Rockford Fosgate took care to build the Enclosure to last, with a cabinet constructed of 5 / 8" MDF that's protected by industrial grade carpeting. It'll stand up to the knocks of life on the street and come back for more. If you've got the room, Rockford Fosgate's ready to bring on the boom.
Important note: make sure that your amplifier is compatible alongside this sub's 1 ohm impedance. Most mono amps are stable down to 2 ohms, so be sure to check your amp's manual.
