Can anyone please help me with a question regarding ARC Audio their 125.2 mini amps and their 5.25 inch speakers. Is the amp and either the XXD or the KS series or Polk Audio's MM series 5.25 speakers as good as I have heard they are? I would like to hear from the people here as I am sure you are all far more experienced than I. I am running a JVC top line head deck and looking for the loudest and clearest sound I can get. Some people are telling me the amp is great and the XXD series speakers are the way to go. I am putting the equipment in a wide open customs audio fairing on my 2005 Yamaha Roya Star. Any help would be very greatful. Thanks in advance
