If you appreciate value and performance, check out Boston Acoustics G1 subwoofers you'll be hard-pressed to find comparable performance and features in other subs in this price range.
The G112-44 12" subwoofer's hefty foam surround allows plenty of cone excursion for deep, powerful bass. The sub's design optimizes performance in small sealed or ported boxes perfect if vehicle space is tight. Integrated sealing gaskets ensure an airtight fit when mounted in a sub box.
This sub will hold up when you drive it hard, thanks to its heat-dissipating vents. Boston's SureSet™ system incorporates replaceable fuses that protect the sub from power overloads and make impedance selection simple. Just move the provided fuses to switch the sub's impedance from 2 ohms to 8 ohms this kind of flexibility pays off when it's time to redesign your system.
Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most 2-channel car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation. Most mono amps are stable down to 2 ohms.
