So I didn't
And made some.
These are powered by a battery.
They are incredibly easy to make I'm 14 I did it!
As ever I am not responsible if it doesn't work or goes wrong.
Try it at your own risk.
This is easy because the speakers already have and amplifier and controls built in. They are very loud and very clear.
These cost me about £2 (50p for the speakers and £1.50 for the battery) I had a spare connector lying around.
What you need
Some computer speakers powered by the main. ( I found mine at a car boot sale for 50p!!!!!!!!!!!)
Electrical insulation tape or you could solder
A 9volt battery
A 9volt battery connector.
What ever casing/box you want to put it in.
Step 1: Getting Started
Find the pack that converts the voltage from mains (240) to 12 or whatever the circuit runs at.
cut the cable running between the pack and the circuit board.
Step 2: Adding the Battery Connector
The yellow wire with the black tape on is not in use
Step 3: How Easy Was That
And create whatever case you want for it.
Mine is yet to have a case because I'm not sure if I want to connect all 4 speakers. Because then it wouldn't be too portable.
Any queries get in touch I will try to assist.

With 2 tweeters and 2 woofers it can be very loud!! : )
