Therefore, each channel puts out twice as much power, and the combined output is quadruple a single channel at 4 ohms. I plan on bridging it to run a pair of polk components rated at 100 rms. A 4 channel amp will be able to run one (or two) subs using two channels (one bridged* sub or two subs) and two speakers running one channel each. 4 channel amplifiers 4 channel amplifiers have four amplifiers or "channels" in one package. Sometimes, there will be lines connecting the two terminals you should use to bridge the amp, as shown on the right. Channel 1 will be labeled A for positive and B for negative while channel 2 will be labeled C for positive and D for negative. To produce maximum power into a single 4 ohm speaker (without increasing the rail voltage) you could simply invert the signal of one channel and bridge the speaker on the amplifier. ...
