Alpine's Halo Series subwoofer enclosures make it easy to add more bass to your system. The pre-loaded R-Series 12" dual voice coil subwoofer provides plenty of bass on its own, but when you want even more, the optional linking kit can connect two together for double the impact.

The Pioneer TS-A2000LB A Series Shallow Mount Pre Loaded Enclosure has an 8 in. subwoofer already positioned inside. Traditional subwoofer terminals are mounted horizontally or vertically. These mounts force wires to be bent to fit which can be difficult if low gauge high performance wires are used. The Pioneer shallow subwoofer's patent-pending, angled push terminals make it easy to connect speaker wires. The straighter connection saves space and makes installation easier. And compact, space-saving dimensions make it easy to install the preloaded subwoofer enclosure in a variety of trucks--standard cab, extended cab, or crew cab.

When Kicker created the original Hideaway compact HS8 powered sub, they wanted to make a subwoofer that could fit almost anywhere and still deliver the performance that made Kicker famous. The HS10 sub adds the extra punch of a 10" speaker and a built-in 180-watt amplifier to give you really impressive bass response from a sub that will still fit almost anywhere. With a Kicker 10" woofer, you can expect serious low end, and you can install the HS10 under most seats to bring the bass right up close. The tough all-aluminum chassis and stylish metal grille protect the speaker and deliver great sound. High- and low-level inputs give you plenty of options for hooking up your sub, and the HS10 can accept input signals from 0.25 to 40 volts so it works with almost any vehicle without adding a line output converter.The Hideaway includes an adjustable low-pass crossover, a subsonic filter to improve efficiency, a phase switch, and a variable +6 dB bass boost adjustable with the included remote control bass knob. The HS10 also offers two auto turn-on options. The package includes a wiring harness for power, signal and remote turn-on connections with a quick-connect Molex plug to make installation simple.
