I just ordered the biketronics BT480 amp, BT451 6.5" speakers and the hogtunes tweeter pod.
eastern performance has the BT451 front speakers and tweeter pod for $339. I got the BT480 amp for $400 + $6 shipping from an ebay harley dealer in MI.
Biketronics has the best warranty.
Been there and done that and MORE than once. For my past TWO scooters, Hawg Wired. Recently added their 150 Watt amp and speakers to my present bike and total cost was well under $800 and the best damn money I've ever spent. Hawg Wired ROCKS ! End of story.
