An amplifier with both high-level and low-level inputs provides flexibility by allowing you to build an audio system using virtually any standard factory or aftermarket source unit. High-level speaker level inputs accept the signal from the speakers while low-level RCA inputs accept the signal from the pre-amp outputs of the source unit. A subwoofer with a single voice coil can be powered by an appropriately matched amplifier or can be combined with multiple single voice coil subwoofers to achieve a variety of impedances to match your amp set up. Single voice coil subwoofers are generally ideal for low to medium-power applications. The phase control feature allows you to adjust the speakers phase to ensure all audio signals are playing together rather than against each other. When bass notes are noticeably absent a quick and easy adjustment to the phase control could provide the perfect remedy.
