Features
Dual Passive Subwoofers: The Focal ISUB TWIN includes two compact, passive bass enclosures designed to fit under most vehicle seats and in tight spaces. The sealed enclosures each include a single 8"x2" racetrack-style driver with an aluminum cone, Butyl rubber surround, and dual heavy-duty ferrite magnets. The driver is protected by a non-removable aluminum mesh grille.
Power: Each of the two included 2-ohm bass enclosures can handle up to 100W RMS (200W peak).
Connection: The ISUB TWIN enclosures feature a single pair of spring terminal connections that can accommodate wire up to 12-gauge.
Mounting: The Focal ISUB TWIN includes four 8" strips of hook-and-loop fastener with adhesive backing for mounting each sub. Both enclosures also feature through-body screw holes in each corner for making a more permanent installation (mounting hardware not included).
