User Manual: linkQ



The linkQ is the perfect solution for an easy subwoofer upgrade to any OEM audio system.  The high-level inputs are designed to accept signal directly from a high power factory head unit or amplifier, simplifying installation.  It features an adjustable 1-band paragraphic equalizer, making it easy to correct unwanted equalization that can negatively affect subwoofer performance.

The linkQ has low level (RCA) inputs, so you can use it with an aftermarket head unit as a high output voltage line driver.  It can also be used in power sports applications as a source unit.  The included remote (RLC) can adjust the level of the subwoofer or serve as a system volume control in power sport applications.
