Make your own DIY 5.1 surrounding audio system...

How to make diy 5.1 surrounding audio system...? 5.1 surrounding audio system First you need 5.1 pre-audio amplifier for the speaker's power amplifier. Because normally every devices have stereo output. That's means left and right channels are there's in for the audio output. But you need 5.1 surrounding output. So I'd prefer DAC (Digital to Analog Converter) device. 5.1ch DAC (Digital to analog convertor) device. Second Yeah if you ready for the next part of the list, then you need 5.1ch speaker's power amplifier. The picture above is an expensive 2in1 amplifier. And it also has per amplification. So yo don't buy DAC device. But I'd prefer to buy class D power amplifier. Because It's very cheap and easy to use. Class D 5.1ch power amplifier. It's also little bit costly. Don't worry! about this. I have an other idea for you. You can make 5.1ch power amplifier with very cheaper. So must need three or more than three 30W-120W stereo power am
