the POLK db series speakers (like in the picture above) i hear are great speakers. I just bought 4 of them for the system i am dropping in my S&S. I think i was able to find 2 pairs of speakers for $130 on ebay. I also picked up a sony marine head unit (with cd AM/FM, usb, and aux) for $140 off ebay. Some people worry about buying electronics on ebay, but i have NEVER had an issue.
