Dimensions

CRUX does not currently publish reliable bare-module dimensions or net product weight for the SONGM-11 on its official product page.

For marketplace listings, I recommend not estimating the product or shipping dimensions/weight unless the actual retail package can be measured.

Performance

The SONGM-11 functions as a radio integration interface rather than an amplifier, so specifications such as RMS wattage, impedance, frequency response, or output power are not applicable.

It communicates with compatible GM Class II systems to preserve factory functions while allowing an aftermarket head unit to be installed. CRUX Interfacing

Important: On Premium Bose Y91 systems, front-to-rear fader capability is not retained. Crutchfield
