How can I make these bluetooth?

[NickMazzy20]

I have a pair of desktop speakers, I soldered a sub woofer to the desktop speakers since it was a cheap way of fixing it, (Btw it works great, It still has the same quality it had before it broken). I was wondering if I can put something inside of my rig to make it Bluetooth. I have seen the USB Bluetooth extension but I don't have a USB port on my rig. Is there something I can solder on the motherboard of the speakers to make it Bluetooth? Or how can I make a USB port on my rig?

Heres some pictures of my rig.
(Also, there is NO eletronics inside the subwoofer, the backing is there for design, the actual bass inside the subwoofer is getting power from the desktop speakers, and is controlled by the desktop speaker)

Get something like that, look for something you can power from your amplifier' power (for 15VDC, I would look at car stereo adapters pluggable into the lighter socket).

You might want to check here, there are some good DIY guides.
