I'm planning to get a set of JL XR650-CSi and JL XR650-CXi. Both have a maximum RMS rating of 150 watts. I was originally going to get two JL 300/2 amps, one for each set of speakers. But I could save about $350 by going with one JL 300/4. So, my question is:
Will there be a significant difference between 75 watts per speaker and 150?
