How to headphone jack on bike

sorry my info didn't help.  you may look into this http://www.soundgate.com/index.php?request=product.details&categoryid=184&productid=454&usereferrer=1

it takes a high power radio and converts it to common ground, which is what most headphones have.

did you try just hooking the two postitives up and one negative up to the headphone jack with out the capacitors. the company I work for we designed and built custom radios for skidsteers with remote mount face plates and headphone jacks and speakers in them we have been building them for over 5 years now and haven't had a radio get ruined because of the jacks. by the way we used kenwood tape decks. also have you tryed different headphones other then the one in your helmet?

Thanks for the quick replies folks!

After trying different capacitance and trying without the resistors I found the problem (duh!). I had used my meter to find a good bolt to use for ground, I thought that was a good idea. As it turned out the first place I picked for ground was not to good. While wearing the earplug speakers I touched the ground wire of the circuit to different locations until I found one that worked, made the audio sound correct that is. Now every thing sounds great!

But...put bike back together and went for a test ride, now I have bad "engine" noise. The audio is excellent when engine is not running, I'm guessing because my connections and cable are not shielded is the reason for the interference. Now I tapped into the rear speaker leads to feed the phone jack, the rear speakers don't have engine noise.

Once more I'm lookin for some savvy advice. How do I get rid of the engine noise?

Thanks every one for your help.

p.s. I left the resistors out of the above circuit. My logic being that if I keep the volume turned down before plugging in I should be alright, so far so good.

thank you,

you did say you had volume control on both you headphones and radio?

did you try turing down head phone volume and up radio

or up head phone down radio

just an idea

Hi folks,

I ordered a noise supressor from JC Whitney, I will try it in line with my earplug speakers and let you know how it does.

I do not have a seperate volume control on my ear phones but do on another set set of head phones and adjusting the volume that way makes no difference.

I got good old engine noise bad, hope to find the cure cause the sound from the ER6's is great when the engine is off or I'm moving along at a pretty good speed (which increases the volume). I can just hang out in the garage with the earplugs in and jam out all day, great sound!

thanks all,

Pat
