Bridging

Information on Bridging Last Updated: 11.08.07

Bridging: Combining both left and right stereo channels on an automotive amplifier into one higher-powered mono channel. When an amplifier is bridged, the impedance that the amplifier actually "sees" is calculated based upon the output of both stereo channels. Here is a simple formula to help define this:


Bridged Mono Impedance = (Y / X)/2

 

Y = impedance of driver(s) (both drivers should be identical)

 

X = # of drivers in circuit

 

One 4-ohm sub in bridged mono is equal to hooking up two 2-ohm subs in stereo, one to each channel.
