First I have read so much regarding speakers and amps etc and everyone has different advice well here goes for me...............Really appreciate any input
The good news about the forums - there's a ton of information. The bad news about the forums - there's a ton of information. The ugly news about the forums - sound is just so stinking subjective. What sounds great to one person sounds ok or bad to someone else and there are so many choices and combinations out there it's easy to make your head spin. Looks like you're already figuring that out so you're ahead of the game.
You said any input, so I'll be brutally honest.
I ran JM stuff when I first started dabbling in audio and pulled it out after a few months. I'm no expert, but I've tried many combinations and do a ton of homework before I buy anything. I will never run JM audio in my bike again and wouldn't recommend it to anyone that asked. Some guys will flat out tell you it is crap. There are guys that swear by it. I will tell you it's not crap, but it is way way overpriced for what you get. Do some searches here and on the other forum and decide for yourself. A lot more votes for crap than good stuff. To my ears it falls between Boom Stage 1 and Boom Stage II. It's louder than Stage II, but Stage II sounds better to me. At higher volumes and speeds they are tinny to the point of harsh on my ears. To me the exponentially cheaper infinity Kappa 62.11 get just as loud and sound better at speed. I'd send them back or cancel the order.
As far as amps you already mentioned the important thing - build for the future. The soundstream and CV are decent entry level amps. If you keep the JM speaks that would be my choice because I bet it doesn't stay in the bike until the end of the season and you can sell the amp for a few bucks and put it towards a new system. Move up in price and you're looking at arc audio 600.4, biketronics if adjustability isn't important to you (at least until the new one comes out, the 4250 will be an absolute beast), upper end fosgate stuff, the new focal fdp sport, and the JL audio stuff is real popular (all of that listed in no particular order). The trick is getting something with enough power to push 4 speakers that matches up well with your speakers. A lot of the 4 channel amps are being used by guys to get big power bridged and don't really excel at true 4 channel ops. I run a micro 4V2 bridged and love it for fairing speakers, wouldn't even consider it in 4 channel mode, not enough oomph.
Lastly, my approach is buy once cry once. I've done everything from cheap to high end. Buy a good amp and you won't be disappointed. You may swap speakers a few times finding what sounds good to your ears, but money spent on a good amp will never be wasted.
