I did not make a hard mental note of where the gain pointer was. However it was about a quarter turn from zero (about 10-11 clock) It would be worth it to ask a neighbor or some one to let you use a meter. Keep in mind that is for 2 ohm speakers. For a 4 ohm speaker the setting would be 22.3 AC volts Voltage = sqrt (125W X 4 ohms)
15.8 AC volts Voltage = sqrt(125W X 2 ohms)
Ya "full" is best in my opinion by pass the cross over. playing with it was my meaning I could of wrote it clearer. I apologize for that when set on high if thats where you like it I thought it was best about 100-110. SOUND is subjective.
It would be interesting if you all come back and say where you ended up with your settings.

I have not posted for a little while but here is a quick flash back and happy ending:
I purchased 2 sets of J&M speakers and 2 amps from Dr VTWIN
for myself and a buddy of mine. He has an 09 street glide I have an 2010 street glide. We installed his first as we had received only 1 amp first and my bike was in the shop getting dyno'd. Speakers went in easily and sounded great on his bike, amp came bout 3 days later and we did install very carefully but could not get any sound out of his bike. after tracing everything and posting here and great support from Shawn at DR VTWIN and John at J&M, Nothing worked we could not get the 1st amp working. The 2nd amp arrived and Shawn and John recommended that I try it in my Buddy's bike, so I did and it still did not work. It was very frustrating but again Shawn was very supportive and asked me to try it in my bike. I got my bike back and installed the amp and it worked. So it seemed there was something wrong with his 09 and John thought it might be a specific problem with a specific vin run of 09 street glides and he was gonna try and figure it out. Anyways we hooked his bike back up to the speakers with no amp and it worked perfectly and btw the speakers rock even with out the amp.
Ok so now my speakers and amp are working and sounding outrageous and the next day I go out cruising and loving the sound and all of a sudden nothing. NO SOUND I'm freaking I email Shawn tell him what happened and he was kinda upset and I tell him I'm gonna try and trace everything and figure all of this out. HERE IS WHAT I FIGURED OUT:
After removing the fairing and checking all connections disconnecting and reconnecting they were all installed correctly. I than noticed that the amp was flashing intermittently 8 flashes where before it would flash on power and than be solid. I could not find anything wrong under the fairing so I traced the power wired back under the seat. First I removed the positive and reinstalled. Still no sound. next I removed the ground. look at picture below.
When I removed the ground I noticed all of the paint surrounding the bolt area and wondered how good of a ground surfface this was. I decided to try a different ground point so I used the strap running from the bottom of the tank, there is a bolt and I attached the ground there. I try'd the radio and WOOOT the radio and amp worked. I now decided to try my Buddy's 09 again of which i just got done tonight and WOOOOOT it also worked. I think this amp is sensitive to ground and I would highly recommend using the ground strap under the tank. THE BEST PART IS THRU ALL OF THIS SHAWN AT DR VTWIN HAS FOLLOWED ME AND SUPPORTED ME ALL THE WAY, AND THE BOTTOM LINE IS I WOULD DO THIS ALL OVER AGAIN BECAUSE THIS J&M AMP AND SPEAKER COMBO SOUND FANTASTIC.
THANKS SHAWN FOR ALL OF YOUR HELP

Jeff,
Again, I must apologize for all the trouble you and Dave had to go through to get the amp working, but I am SO SO SO HAPPY that you guys are now enjoying the same sound Al and I have been enjoying since we installed the amp.
I have forwarded all the information over to John at J&M, so they know where the issue lies. You have narrowed down the issue it seems and I am sure John will be pleased so nobody else will have to go through what you guys had to go through.
ENJOY the amps and please let me know if I can EVER be of any assistance to both of you!
Thank you!
Shawn

If anyone else is interested in getting one of these awesome amps, we should have more in stock tomorrow and Wednesday of this week. We are ordering as many as we can.
They won't last long...they haven't so far. Every amp we get is sold within minutes or a couple hours after it's arrival to us.
If you have any questions, let us know!
If you are local to us, come on by for a full demo of the 7.25" J&M speakers and J&M amp.
If you would like us to install the J&M 7.25" speakers and/or the J&M amp, we would be more than happy to.
Thanks!
Shawn

Thanks Shawn
I really believe that the problem was not because of the J&M amp but because of a bad ground point on the Street Glide. It was actually fun playing detective and if it was not for your support and the fact that I believed that you would refund our money if I could not get it working, I would have simply returned the amps. I really hope that anybody reading about this is not discouraged because the amp and speakers really do rock and The install is actually pretty easy. If anybody has any questions please feel free to contact me AS i HAVE NOW INSTALLED AND UNINSTALLED THE AMP AND SPEAKERS ABOUT 10 TIMES. BTW I am a non mechanically coordinated kinda guy and if I can do this so can you. Before i bought this product I never had any contact with Dr VTWIN and at first I was pissed off but Shawn contacted me and I can tell you
Dr VTWIN does stand behind his products.
