The following aspects must be considered when assembling a stereo: 1, how much money are you going to invest; 2. Are you an enthusiast HIFI (because enthusiasts have higher requirements for audio equipment than ordinary people); How many rooms are you going to put your audio equipment in? 4. Do you assemble audio equipment to watch movies or enjoy music? Next, I'll talk to you about audio equipment. A complete set of audio equipment includes: power amplifier, equalizer, speaker (speakers are divided into front, middle, rear and subwoofer), CD player, heating wire, etc. If you are not an enthusiast, I suggest you buy the whole machine, because the sound effect of the whole machine is better than that assembled by yourself (I mean on the basis of the same price). In short, what kind of audio equipment to buy at what price.

I hope my answer can help you.

If you have any other questions, I suggest you go to the love HIFI forum to find out.
