to lock it onto the wire.

Fasten each NCB flange to the 
joist with two screws through 
attachment holes.

Slowly cut along the 
outlined mark with a 
drywall knife/saw, trying 
not to chip out the 
drywall excessively.

To keep polarity correct, connect the amplifier’s + (positive) channel to 

speaker’s + (positive) channel and the amplifier’s - (negative) channel 

to the speaker’s - (negative) channel. To avoid shorts, keep stray 

strands clear of adjoining connectors.
