I am going to have the audio shop to install the Clarion center speaker(it comes with a 50w amp) and Infinity Basslink. I am very sure I will need to change the speakers and probalby add an amp to drive the new speakers. What is your recommendation on speakers/amp for my set up?

I am thinking to get the Rainbow or Focal speakers. I am wondering, will theese speakers overwhelm the center speaker.

Thanks.
