Hello Guys , In this Instructables I will instruct you how I made a simple high power home theater using reclaimed speakers . It is very simple to make , I will explain it in further simpler .

Lets gets started ..
Step 1: Parts and Tools
Female USB jack https://goo.gl/PQBebN
Female 3.5mm Audio jack https://goo.gl/7WirBo
Old speakers and Amplifiers https://goo.gl/Ysj2Cj
Wire 22G https://goo.gl/KtH7WZ
Screw Driver https://goo.gl/5yN0TJ
Soldering Iron https://goo.gl/5SU4uM
Multimeter (optional ) https://goo.gl/zWb84X
Step 2: Block Diagram
It is simple to understand the block diagram
A common input is given to all amplifiers (Left , Right , Ground )
A Common power supply (Optional - need not to be common supply) connected to all amplifiers .Reduce to voltage at required levels with Voltage regulators .
Step 3: Watch Video First !
It will be clear , if you watch before making . Because it is very helpful to understand and improvise the thoughts .
Further clear photographs with explanation is given in below steps .
Step 4: Circuiting
1. Identify Input and Output connections of control unit .
2. Identify the output (L ,R ,GND) going from control unit to amplifier and patch the wire to direct it as input to other amplifiers .
3.Feed that wire as input to the other amplifiers .
4. Connect a common power supply to all amplifiers by reducing voltage by voltage regulators ( In my case it doesn't require )
5. Better to audio jacks for connectivity , because we can unplug it when required .
That's all guys
