J&M 7.25 speaker 250W amp problem
I just installed the 7.25 speakers and 250W amp in my 09 street glide. I love the sound but having problems with the amp not powering up sometimes when I start the bike. The face of the radio is showing power but no sound.If I turn the bike off and restart it the amp will power up. I rechecked all my connection just to make sure I did not miss something. I call J&M service and they said they have seen ths problem in the last couple of weeks. They suggested it wire tie the fuse into the holder to make sure it was not working loose. That was not the problem. Anyone else having this problem. They told me to give them 30 days to come up with an answer. I think they should just replace the amp. What else could it be???

i have found the main power connector from battery that connects to the amp was causing my problem .. also first amp j&m sent me the main power cables going into the amp would cause amp to cut out when i would ride through bumps... i cut the orginal power connector and replaced with a molex type , added di-electric grease and my problem was solved.. if the amp see's any disruption in voltage , ie green led on lamp will flicker thrn the amp goes i to protection mode and will shut down..only was to get amp on again is to cycle power off/on.. remove your fairing , play some tunes and wiggle around the power cables and see if you can make it cut off... also a pinched wire from battery to amp can cause intermittent problems... and of course a bad ground connection... hope this helps a little.. give john a call or email.. extinguish above possible issues and then have your amp replaced...
cheers...ride safe..

I called your shop today but Al was out so I had to talk to someone else. This guy felt I had a ground problem and suggested using the tank bolt under the seat for a ground. I don't had a problem trying anything but a friend of mine has the same system on a 06 street glide and I checked his ground and he has it on the battery. His system works great and has never cut off. I called J&M today and was told John was handling all these anp problems and I needed to email him and he would get back to me asap. I'm going to try another ground location and if this don't work i'm sending it back to J&M.
