You sure about that? My understanding is that on any amp if you connect speakers in parallel you reduce the total resistance the amp sees, and the current through the amp increases. Take it far enough and you will fry something. key formuale are 1/Rtotal=1/R1+1/R2+1/R3.... and P=RxI^2
So if your amp is rated for 4 ohms and has a 4 ohm speaker, and is a 100 watt amp, max current would be sqrt(100/4)= 5 amps. Add a second 4ohm speaker and your total resistance drops to 2 ohms (1/R=1/4+1/4=1/2, so R=2ohms) and I=sqrt(100/2)=7 amps, nearly a 50% increase in current.
Correct me if I'm wrong, but that's my understanding of it.
