Amp Efficiency

[codi]

heyy every one this might be a totlay stupid question but, one day when i was laying in bed i was thinking of car stereo as usual and i thought, would it at all be possible to use the motion of the woofer to produce energy to give back to either the amp? like the motion of voice coil in the magnet

if some one can give me an explination to me kinda dumb question that would be awsome thanks

I don't think that'd work. As when the amp puts power into the speaker voice coil, it changes a magnetic load inside of there and that causes the speaker to move. (Hence why the magnet is there). Not EXACTLY sure but I'm just guessing on that. (awaits for someone more experienced to answer this question)

Lets just say no that's not possible and leave it at that.

Possibly use the movent from a passive radiotor to create a small AC chrage, but it owuld never work OR be worth anything.

hahaha so it was just a hopeless idea on that one, and thanks for letting me know your thoughts on this

and it would be awsome if it worked because then you would totaly save lots of energy that doesnt have to come from the battery and alt
