On your four-channel amp, you should see 8 terminals: channels 1 through 4 each have a positive (+) and negative (-) terminal. A 2 channel amp can also be bridged to power a single subwoofer. The mean that when you connect the both to your amp the total resulting impedance is 4 ohms. Speaker Out signals carry more than just the audio; they also carry significant electrical energy (power, which drives the speakers) that the line level audio inputs on powered speakers can. This would give you a Mono Cabinet, were all the speakers were wired to the same output stage of a Power amplifier. By Danny Briere, Pat Hurley. Lastly connect the negative terminal of speaker 'B' to the negative terminal of the amplifier. That way, each speaker will receive 250 watts (not considering the change in amplifier power at different impedances, and not considering cable losses). The sub will suck nearly no current from the signal (so your mains will still get almost all the juice), expensive subs have nice crossovers you can use in this configuration. Unfortunately, true multi-zone distribution systems are normally built into onl. REL Sub Bass Systems can be integrated into a surround sound system both high level (connected to amplifier terminals) and LFE. It is also worth noting that unless your speaker is powered, you will need an amplifier to run sound through the speaker. The right channel is the only one monitored to turn-on power; applying signal on the left channel only won't wake the amp. It features two audio line inputs with a loop out to another zone, receiver, or device from Line 2 source. But you might also come across a subwoofer that uses stereo RCA or speaker wire connections. Two 8 ohm speakers in parallel gives a total load impedance of 4 ohms. Mixer to sub to amp input then to speakers. I think the nominal rating would still be 4 ohms.
