Okay guys, I'm about to start putting together my system, and I've come up with a rough idea of what I want. I was thinking of RF Power series 5 1/2" coaxials, RF Punch 6x9's and either 2 12" or 3 10" Alpine Type-R's. Probably two Audiobahn amps to power it all, an Optima Yellowtop, and an Audiobahn 1F cap. I'm no expert on sound systems, so if anyone knows any reason or experience why I shouldn't use any of the above, please notify me.
