a strapable amp is an amp that can be run in slave or master it has what looks like a telephone jack in the side of it you plug a telephone looking wire into it and the second amp takes the settings of the first hence the master and slave. if im correct correct me if im wrong o great and powerfull moderators! lol
amps that support strapping, like some of Kicker's mono amps, allow you to connect two identical amplifiers together, and invert one of them so the pair acts like a bridged stereo amp, putting their combined power into a single load.
