I just wanted to clear a few things up. I noticed a couple different posts on here concerning speakers. It should be noted that buying a speaker does not make anything louder. The idea here is to get more CLEAN power to the speakers. Speakers can only provide so much help, if they are being powered by just a head unit (any aftermarket CD player-alpine, sony etc) they will not perform very well at all.
I can't comment on the HK systems in stock bikes, cause I have never monkeyed with one. But, I installed car stereos for almost 10 years and I can tell you that all those head units you see at Best Buy etc that say "40x4" and even 70watts x 4 are full of it. The in dash units only power source is coming from a tiny little IC chip inside the cd player. That is why when you put nice speakers in the fairing and crank up an alpine of sony cd player it can sound distorted and otherwise crappy. That speaker needs a true amplifier that is putting out continuous power, not a head unit that peaks at 40 or so watts per channel with 30% distortion.
This isn't meant as a dig against anyone btw, just wanted to try and help some people out who aren't sure about this technical mumbo jumbo.
My preference for my electra is the Biketronics Titan amp. This baby rocks. I have the Biketronics 6.5" ordered and can't wait. The J&M don't seem to be worth a crap.
Anyone else notice the J&M speakers seem to be flawed in design? The grills ride right up against the surround on the speaker. When you turn it half way up, the speakers slap against the grill causing horrible sound and tearing up the driver. What water head designed these????
