If you like to listen to your radio like I do (guess I'm a dying breed) I wouldn't go with the NVX amp. I installed one an it makes most FM stations static. The Cerwin Vega B 52 didn't do that. I think I burned up the B 52 my not shutting off the automatic volume control or speed volume what ever it's called. When you install an amp shut this off. I ordered some ferrite cones to see if I can reduce the static, I'll post if it helps but they're on the slow boat from China.

If I were to do it again I wouldn’t hesitate to buy this setup again.

I did a XXRK-700SP4-14UL and originally bought the version that did not require a radio flash. The result was a great sounding system sitting still, but when the bike started, the bass response went flat. I caught up with them at a rally recently and they changed out the cables and flashed the radio and amp. Now it sounds great at all speeds. If you go with J&M, just do the Stage 5 setup and send them the radio for a flash.
I don't know why they hate on J&M so much here. They have always been helpful and friendly. I get that some think they are paying too much and can do it cheaper by rolling their own, but some of us don't have the time or patience for that. I just want to buy a system that someone else has already figured out and I don't mind paying a little extra for that. I'm not an audiophile, but I've listened to a lot of bikes and I haven't heard anything yet that sounds noticeably better than mine.

I got the J&M treatment twice. The first time, it was $1,000 while at Sturgis and by the time I got home I realized that was a total waste of money for the slight increase in performance I got. So I talked to Jim, and told him I was disappointed, so he talked me into upgrading to the full high end Jokker 6 speaker system the next year, with a total outlay of that point of over $1,800.
Didn't help when tweeters fell out of the grills on the way back, punched holes in the fairing speaks, and John said it was my fault for not noticing it quick enough? Like I'm supposed to tear off my F***ing fairing in the middle of a 920 mile ride home? But, I lived with it for a couple of years. Certainly better, but I was still underwhelmed, and worse, my brothers Soundz system with the Focals just totally stomped me bad. He just loved to pull up next to me with a big grin, and play right over this supposedly J&M high end system.
I started reading up here, and this spring, I replaced the Fairing Jokkers for some Moto G2's, and the J&M amp for a SD800 for a total spend of $500 Total. Totally blew the crap out of the previous set up. I'm pounding over my brother at this point by a very large margin. Keep in mind, I'm still running the lower 7.25 and rear Jokkers, which you can't even tell are running until you put your ear right up to them. I'm now waiting for the 8" lowers for PRV's with set of MMats 6x9's in the rears, so I can trash the rest of the J&M stuff and put that nightmare far in the rear view.
The bottom line is, there will always be the koolaid bunch who simply don't care to learn they bad got reamed. Upgrading a bike system with a relatively mild setup - Amp, Fairing, Lowers, and Rears, is very easy, especially with all of the great guys helping here. There is just no reason for anyone to toss away good money on mediocre, over priced stuff, when you can do so much better if you are willing to read a little here and educate yourself. If you're lazy, of course, don't bother, but coming here to proclaim how great J&M stuff is mighty laugh worthy.
My .02 fwiw, coming from a guy who blazed this trail and got burned.
