TV’s
M650-GM
processor seamlessly converts GM’s MOST
-50 audio bus to low level (6 channel) RCA,
S/PDIF or TosLink outputs. Adding an aftermarket amplifier to the OE IO5/IO6 system has never been so easy
or seamless. This plug & play kit integrates with various OEM data networks to retain OnStar, door chimes,
volume control, full fade and balance (analog only), treble, mid-range, bass control & Bluetooth voice calls
with no external speaker (true OEM integration).
NOTE: the OEM amplifier must stay connected in the vehicle
to maintain complete OE functionality at this time.

IMPORTANT NOTE: Many GM vehicles have poor chassis grounding. BEFORE connecting this
interface, check the GROUND to the amplifier using a digital multimeter. If resistance (compared to
vehicle battery negative) is greater than 1 OHM, run amp ground directly to battery or find a better
ground source. Warranty will be VOID for the M650 if damage is caused due to faulty ground(s).
