hi, I need someone to help me clarify a few things. I have the bose 191 ceiling speakers(50 watt 4/8ohms)x5. I've seen an amp with 100 watts x 6 (8 ohms). Is this too powerfull for my speaker? will by speakers burn out? and if anyone can explain what 100 watt x 6 means etc. pleaes let me know. thanks.
