Hi My friends Recently I buy a pair of speakers. "Kenwood kfc-hqr7100" I need a suitable amplifier to get more powerful sound from it. I know peak power of this speaker is 600w and rms power is 150w. I want to know that whole RMS power per this pair of speakers is 150w or 150*2=300w? Which amplifier can I buy : 1- 2 channel amplifier with 2*150w output 2- 2 channel amplifier with 2*75w output
