I'd say just don't push it loud it stresses the amp a lot to have to do that, I used to do that but I had a weak link in one of my mids. It's really not recommended, I'd say just low level is best. It's a way to hurt rcvrs and spkrs but if the optn is avlbl then they can handle it but you put a heavy load on them and that at semi loud vols could lead to clipping distortion, etc, which is never good. I never realized it. I'd say only do it at low volumes. Depends also on speakers, they must be at least8 ohm. I would say only do it at very low volumes and if you can not do it at all it's better, thats one of the most common ways to harm unit, but I'd say u could use judgement and maybe take it easy on the bass and vol. I don't know too much but good luck, there's a lot of threads talking about this spkr/ amp impendance measured in ohms, once you have that down it's okay. Um that's what we don't want is to use these things past their limit, it'll distort and cause damage a lot easier...a lot easier, just be really nice to it when you use a+b. Not sure about strength of that rcvr but even heard lots of people saying not to use a+b on thousand dollar units. Hope you find your answers.
