    Motorcycle MP3 Question

    Here's what i got......

    I have recently finished installing an mp3player (Creative Nomad JukeBox) and speakers (Bose cubes from an Acoustimass system, series II) on my new motorcycle (1999 Honda CBR 600 F4) being powered by a Jensen 88W amp. I know jensen is not the best pick, but it had the best fit to be placed under the seat.

    now here's my situation....everything works fine and dandy with the bike off, and while moving. The problem begins when I'm at a red light. The sound quality diminishes and sounds slightly distorted. i'm pretty sure that it has to do with a lack of power when i'm standing, because if i pull the throttle a little and increase the revs slightly, it sounds fine again. My question is, what can i do to help this. I know the easy answer would be a better alternator or battery if it were a car, but i don't know if I'll be able to find a higher output generator for a motorcycle, and I already know that Optima does not make yellow tops (their high output battery) for motorcycles. My other option was a capacitor but the 1/2 a 1 farad ones that I've seen are huge and size is a definite issue and i'm not even sure if this would help. If it would, what size cap would i need? Or are their any other options any of you can think of? I would appreciate any help or suggestions.

    I'll get pics up of it soon.

    Thanks in Advance

    I capacitor will not help your problem. It looks like the only choice you have is to get your alternator rewound for a higher current, replace the battery with something else (Hawker makes some small gell cells) or bump the idle speed up.

    now THAT... I gotta see....

    I may be missing the point, but do you hear the sound thru your helmet? I thought headphones would be the only solution?

    He has speakers... you can hear it just fine through the helmet... My dad has a road or "touring" bike which has a factory stereo on it. It adjusts volume with speed which is a nice feature... anyway you can hear the sound just fine... headphones are illegal in most states if not nationwide in the US. The helmet has to be able to be heard through for the same reason you can't wear headphones, you need to hear automobile horns and other alarms such as emergency vehicles.

    I've also been thinking of a moto-mp3 system for a while. It would be easy and nice and hidden on a big touring bike, since there is a lot of big storage compartments and usually a stereo... but I don't have a bike of my own or anything, I would like to see pics too

    I am puzzled as to _where_ on a CBR you could mount speakers. The CBR is NOT a touring cycle

    Well, in Illinois, there is no helmet law and as such I do not often wear one, (yeah yeah, my mom's yelled at me enough so please no - you should wear a helmet - arguments) so i can hear the sound very well.

    as for where i mounted the speakers, I have them mounted right on the end of the winshield in front of the side view mirror mounts. Hard to explain, I should have pictures very soon

    as for the volume changing relative to your speed, if anyone has any idea on how i would be able to implement that, that would be the next thing I would love to do.

    Hey guys I've got to say I love this idea. For the last couple of days I have been playing around with how I could set it all up on my bike. So I have to ask your help with any ideas you guys have to contribute, like if its possible to mount speakers on the bike and how to go about i or to go for a single wireless ear piece etc.... just throw around some general ideas. Thanks!

    Bikes vary... post what kind it is and a pic or two... that should inspire some people's imaginations.

    Mate its a Kawasaki ZZR... so basically like a small jap sports bike. I am just wondering would it be better to have small mounted weatherproof speakers or to go with a single wireless ear piece? Any ideas or suggestions... just throwing the idea around. Cheers!

    I would go with the speakers for safety and legal reasons. The only drawback to them, would be that they are more visible and more likely to be stolen, but if a theif is going to see and steal them, then he is probably gonna steal as much as he could.
