Help needed for a diy bluetooth speaker Answered


I have 2, 10 Inch JBL speakers from an old music system. I dont have a photo right now, i will post i later. i am not sure if its a woofer or a speaker coz it have 2 magnets below. one over another and inside there is also a small speaker in the box. So i got 2 big speaker(or woofer) and a 4 inch woofer driver from a jvc multimedia system.

I am kind of an audiophile and i want help to build a good boomboX with whatever i got. i am familiar with wiring and soldering and that kinda stuff. but i dont have anything to fabricate any circuit boards. So pls suggest me parts with low cost and those which can be bought inside India. I also have a bunch of 3.7 V rechargeable batteries from powerbanks and rc helicopters. But dont have a way to recharge them or use it for a regulated supply
