Would the Alpine MRV-F540 80watts RMS x4 be a good amp for the Alpine SPS-171A component sets?. Right now I've 2 sets connected to the deck & whenever I raise the volume they distort horribly. I'm looking for an amp that will make them sound good & without distortion. Also, I've read here that new speakers have to break in when they're new before they start to sound their best, is that true?. Help plz....
