Ok only thing you will need is :old pc speakers , soldering iron , screwdriver , 9v battery  

Step 1: Open your speakers

Open your speaker and cut the wire that goes from transformer to the circuit board and connect it to the battery ( 9v battery)
Does it matter which wire gets connected to positive and ground? How do you go about checking that?
check the wires that goes from transformer (black is - and red is +) , its matter becouse otherwise it will dont work
mine has blue and blue XP
look if you have 4 diodes on PCB if you have you can put battery how you like
Have you got a good idea on how to make it rechargeable?<br> <br> It would be super practical if it could recharge using USB,<br> <br> Not sure how to use USB 5v to charge a cluster of AA batteries that would need to deliver 9v afterwards. I'm thinking parallel 5v charging and then serial 9v delivered to the speakers, but it may be impossible.<br>
you can use charger for 9v batteries,but through usb i don't know , only if you use 8*1.2 (9.6v) rechargeable batteries and then charge 4 batteries and then other 4 but this is unpractical and big
