Thanks for your response.
They make a loud popping noise (similiar to the "pop" sound that it makes when you turn them off, but repeatedly). I'm using the system mostly for home theatre. The "clipping" usually happens during "bassy" scenes in movies. The fuses burn out really easily, too. Usually if it makes this popping noise for too long, the fuse will blow.
Is this because the amp is getting overloaded or the speakers themselves are getting overloaded?
The amp is rated as a 150W x 2 but sure doesn't seem to make too much bass before it gets overloaded and start clipping. Would a different amp help?
I'm trying to understand what component(s) in my system I need to replace to get a better theatre sound. The Spica / Kinergetics are a great match for sound, but I can't figure out if they are suitable for home theatre. Do I need different speakers or different amps?!
Thanks for your help.
