I have 2 sets and Love them, I had the Boss cans for the past 2 years and there is no compairson. The Fusion are loud and have a nice sound and they look awsome.
Heard em, seen em.... bada$$. The quality of the housings are second to none, and the Diamond Audio speakers are loud and clean with the right power to them. Highly recommended.
Check out the specs on both the cans and the speakers at Wakeside.com
I have 2 sets of Boss cans on my tower and have spent time in a boat that has the Fusion T Series speakers and they blow mine away. This boat also had less power going to the tower then my boat. Very nice stuff.
How much - No less than 100w per channel of good clean power.
What kind - Up to you. Don't get fooled by overhyped power ratings. Quality clean power will make those speakers scream! Check out the 4-channel PPI amps.
The one I heard had a Phoenix Gold T400 or T600 amp going to the speakers. Any decent amp that is around 4x100 or so would do the job with those speakers.
I have all Hifonics amps and have been very happy with them. They are high end amps and you can get them on eBay for very cheap.
If i plan on only having the two fusion speakers on my tower then can i get away with having a smaller amp. Also what would they sound like if i just hook them up to the head unti untel i had more money to buy an amp.
I second Brents opinion. Jasen and our buddy Larry has em. They blow the socks off my 5 and 6 MBQ Speakers in the BOSS style cans. I can't get mine as loud or as clear and I don't know why. My understanding is the Fusions have car audio style speaks but I don't know why they sound so much louder/clearer. They are the best car audio style tower speaks I've heard to date. ...and they look bad arse.
