Helix U 10A Underseat Sub Compact 10 Inch Active Subwoofer with Bass Remote. HELIX U 10A Bass is in the smallest hut -If mounting space in the vehicle is scarce and existing car hifi systems badly need the “extra kick” in the low frequency range without great effort, the new HELIX active subwoofers U 10A and U 8A are the right choice. Driven by powerful, integrated Class AB amplifiers with 180 W RMS, the heavy-duty drivers with their rock-solid aluminum cones and heat-resistant voice coils easily transform the amplifier power into punchy bass. Equipped with a 2-channel highlevel input with automatic turn on function as well as a 2-channel lowlevel RCA input a seamless integration is guaranteed. And thanks to the especially shallow cabinet design the installation will be a no-brainer, especially if space is extremely limited – these small “bass boosters” may even fit under the seats, for example.
