Equalizers & Sound Processors Information


Information about Digital Sound Processors: Most original factory stereos use preset equalization curves that are designed to get the most out of your car's factory speakers. When you upgrade to aftermarket speakers, your OEM stereo's equalizer preset curves do not adjust, resulting in under performance from your aftermarket speakers. Processors reshape the output of your factory stereo's preset equalization curves to ensure you get optimal performance out of your aftermarket amplifiers and speakers. A parametric sound equalizer helps you tune your system to the perfect balance. These audio equalizers will also help eliminate infrasonic distortions for a crisper and clearer audio output. Adding a sound equalizer to your car will optimize your system's performance. Electronic crossovers divide your music into high, low and midrange frequency ranges. Some of the units we carry are combinations of both stereo crossovers and stereo equalizers. Call us today if you need help choosing the right combo for your setup and budget. 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.
