Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Built-in Bass Reconstruction
Bass reconstructors, or bass enhancers, improve low frequency reproduction in a car audio system with at least one subwoofer. These bass expander products will help your subs produce accurate bass thumps.
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
