In Reply to: How do I Wire 3 speakers? posted by AudioHeadSTL on October 3, 2005 at 12:22:04:
Hi mate,wow thats confusing.I think you need to make sure that your A + B speakers Equal 4 ohms or more.Are they both 4 ohms?I'm sure when you select A + B the circuit connects the speakers as an 8 Ohm load,but that all assumes 4 speakers.And you want to connect 3 and your amp doesn't like it.
Think you better go to this site and have a look.http://sound.westhost.com/bridging.htm

One would think that when you attach 4 speakers to 4 channels that it would drop into 4ohms, but that would cause the amplifier to increase its power (double the watts); however, the opposite happens the sound softens. When I wire 4 speakers in parallel to the A speaker channels THEN the power boosts and it sounds great. But, I only have the two small speakers (New Bose 301, which sound great by the way) and the one DCM12a Loudspeaker. It produces great base so I wanted to utilize it. No Sub out on the amp. Someday I’ll get another DCM, but for now I only have one.I’m wondering if there is a way that I can “fake” a speaker on the B-left channel in order for the amp to think there is 4 speakers hooked up?
What about wiring the DCM speaker to the B channel but only use the B-Left pos to the B-Right neg? This will cause the amp to see 4 ohms on the B speaker set, won’t it?

Try a dummy load.Buy a resistor 3.9 ohms(4ohms)or I used an old tv speaker and roll it up in a towell so you dont hear it stressing out(probably not healthy for your amp).
Answered in another asylum.
What? I don't understand your point Kal Please expound...
