Bought J&m speakers and amp from Dr V, not bashing them in any way they were great to deal with and i have yet to contact them with my gripe! With that said i live in upstate New York , weather was wonderfull today 60 had to run to the store for the little missy to pick up some fixins for a turkey dinner, had just come out of the woods from hunting and i thought i need to ride the bike to the store, and to pick myself up a new bottlr of bourbon! Enough rambling, my stereo sounds like ****! playing my i pod, speakers crackle, **** pile full of static, want to replace the stereo, what will work with all my stock controls with upgrade in stereo? High tech is good dont like to half *** anything! Again Dr V im sure will be more than helpfull!

 

Did the ipod play ok before the upgrade? Maybe try turning down the volume on the ipod, it could be the gain is set too high. Does the radio play ok? How about a cd? If it is just your ipod, it is probably your cable/connection between the ipod and the accessory jack. I had to clean my headphone jack on my ipod and get a new cable before mine would work.

I upgrade all 4 speakers and love em.

Good Luck.

 

I am not sure what they sold you but, you need a speaker with a decent size voice coil to handle the necessary excursion for bass response and volume needed to overpower the road noise you encounter on a bike.
Boston Acoustics makes a 5 1/4 speaker with a 1" - 2" voice coil depending on the price. The SR55's work very well, a little on the high side but they jam. A small 4 channel amp that is not a cheap chip amp will power them real nice. Kenwood & JL make some real nice sounding and performing ones.
Sounds like you're over working your speakers and clipping your amp/radio/system.

Good luck, any other question feel free to ask (I am in the stereo biz here in StL, since 1984 have done many bikes)

 

I have the J&M 7.25s and power them with a 100 watt kicker amp.......they dont snap crackel or pop

sounds like you have a bad ipod cable

 

It all comes down to the quality of the music you downloaded to your IPod in the first place. If you record it in low quality in order to fit more songs on it that's your problem. You are just hearing the imperfections in the music quality itself. Put a store-bought c.d. in the system and listen to it. If that sounds good, the quality of the music on your IPod is just bad. This system will also let you hear all of the imperfections in FM music as well.

One other thing that it could be is, I don't know when you bought your amp from them, as they've just recently changed the appearance of the amp (supposedly it's the same electronically though), and another forum member posted a picture of his. In his picture the gain controls were exposed and we have a tendancy to mess with them. When I got mine, the gain controls were covered with a J & M sticker so I didn't mess with them and mine sounds fine. But if you've messed with your gain controls that could be a factor as well.

My stereo sounds best when playing c.d.'s because the quality of them is better than FM frequencies or IPod recordings. It's just that these speakers and amp have enough fidelity that you're going to hear more of the imperfections in the music you're playing.

 

Could it be a ground problem ?? Does it sound bad with a "Studio" recorded CD ???

 

Oh, and by the way, if there is something wrong with your unit, don't worry. I blew one of my speakers, called Dr. VTwin, they said mail it to J & M, which I did. They mailed me a new one in less than a week. Good customer service from both Dr. and J & M.
