MX OEM ACCESSORY OVERVIEW
Maxxsonics OEM Accessories are the answer for getting more power and better sound from an existing car audio
system when it is improbable, impractical and sometimes just impossible to change an aftermarket head unit. The
following is a brief description of each MX OEM Accessory. More detailed information is included in each models’
individual section.
*MX-1 & MX-2 models feature Maxxsonics’ innovative Audio Signal Sense. This feature allows for the MX Controller
to turn on when speaker audio signal is detected by the unit. This feature will then send signal to the amplifier in line
automatically turning the unit on as well. Audio Signal Sense has a 60 second window from the time that signal
ceases to when the MX Controller and amplifier power down. This feature is included so that your controller and
amplifier do not power down in between tracks or while changing discs etc. (Both MX-1 & MX-2 feature Audio Signal
Sense as well as standard Remote wire capabilities.)
MX-1 Premium High-to-Low Level Converter:
Easily add an aftermarket amplifier to any OEM radio system with this deluxe line-level controller that converts factory
high-level speaker wires into unbalanced low-level (RCA) outputs.
MX-2 Deluxe High-to-Low Level Converter:
Conveniently converts a stock head unit’s speaker wire signal (high level) into an RCA (low level) signal for use with an
aftermarket amplifier.
MX-3 Bass Controller:
Working in conjunction with an aftermarket radio and amplifier, the Bass Controller takes the designated radio
subwoofer or full-range stereo output from the radio and processes the low frequency bass notes. In turn, this
enhances the bass response, increases linearity, buffers unwanted transient noise and improves the frequency range
for overall improved bass quality.
MX-4 Add-A-Sub High-to-Low Level Converter
This unique Controller provides the ideal way to add more bass without changing an entire OEM radio system.
MX OEM ACCESSORY SETUP
To test speaker channel voltage, first you'll need a DMM set to measure AC voltage. Play a musical track on the radio.
Turn the volume up to maximum undistorted level (by ear). Measure at the speaker or the wire. Dial your interface box
accordingly.
