Ok So i was thinking about how to put a system on a bicycle and i was thinkin about how it could without killing batteries. so this is what i was thinking
1) Get a decent stock alternator or a plug in type harness and battery from an electric wheelchair. If alternator then use a sprocket and another chain to hook to my one chain and set the ratios up so that even though it wont be spining fast at all that i could still use it or the battery and plug in from a wheelchair so i could just plug it in.
2) maybe a 12" or 2 10"s that would require very low power so i can get a small amp that would require the least amount of draw from a battery such as funky pups which i believe only are 150 watts rms which would be great. then get a small 4 channel and power a decent set of co-ax's or comps.
3) Hook up a headunit to the battery with everything else and possibly power the set of co-ax's/components off the HU to lower the draw.
4) Install all this within the frame of the bike and use fiberglass or sheet metal to cover everything inside so you cna just see subs/speakers/HU
Now does anyone have any advice to how i could do all this. Ill proly start looking around for some low power amps and subs later. Any input that is from assholes would be great.
