Video:https://www.dropbox.com/s/o7r4dud1zymu4f2/20190104_140406.mp4?dl=1I made a backpack speaker from an old surround setup. Built the speaker from wood and vinyl wrapped it with carbon fiber. Bought an amp from ebay:https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F262988158647Got a USB RGB led strip and added a custom circuit to the controller to make it change color to the beat.
What kind of battery are you using? Pic related, I've also been putting together a portable speaker.
>>1553646Pretty old case. Nice exept the fragile mounted and not protected speakers ..
>>1553658What do you mean by fragile mounted? If you're talking about the stiffness of the suitcase, I got around that by making a separate plywood cabinet inside the case. As for the unprotected speakers, I'm just a sucker for aesthetics and didn't want to hide the pretty looking vintage speakers
