The Infinity perfect 6"s (tweeters set to -5db) do produce a little more bass in the front over my old 4" boston pros, even with a meer 50w going to them. I have to install the new amp still, that'll give em ~100w RMS
The install was fairly easy, doors came right off. The hardest part I suppose was the crossover mounting on the inside of the inner part of the door. I mounted the tweeters in the corners of the door (near the vents) I still gotta get pics of that and the entire setup.
Going on a suggestion I set the crossover at -5. People have said there kind of 'tinny' because of the metalic tweeters. They definatly sound good. I can't say completely untill I have the other amp in and get the 100w going to them though.
