Haha, I must have missed all of that. If I were him I'd bridge that 450/4 and have plenty of headroom for each side.
OP: burn the Focal Tools disc over at
diymobileaudio.com(just search for it, you'll find it), play the sample tones they give you, and simply use your EQ on your radio to only cut the frequencies that seem too loud to you. An easy way is to start off with the lowest one, and spend maybe a second on each one as you're going from track to track. That way you can easily tell where you have unwanted peaks in your response curve. Correct those peaks and you'll be able to turn your music louder without it seeming harsh, and because of that hopefully have a more pleasing experience at high volumes. I did this and it worked magic on helping me get rid of a couple nuisances.
