Definitely feels good to do it yourself and save a few bucks in the process!

I'd highly recommend comparing the Polks to the WetSounds for your cabin. I am running Polk MM's powered by Kicker amps in mine. My buddy is running WetSounds powered by Rockford Fosgate in his. I spent about half of what he did shopping on-line and doing the installation myself and he claims mine sounds just as good if not better. Power ratings for the 6.5" are about identical so if you have them properly amped you'll be very happy with Polks!
