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.
