Perhaps the most difficult part of amplifier design is powering the subwoofer channel from the on-board 12 volt network. There are a lot of reviews about it in various forums, but it’s very difficult to make a really good converter using the advice of experts, check this out

We make a simple sound amplifier with our own hands. We will need the following: 1) Coil: L1 5 μH 2) Resistors: R1, R3 2.2 kOhm; R2,R5 22kOhm; R4 680 Ohm; R6 2.2 Ohm; R7 10 Ohm. 3) Capacitors: C1, C4- 4.7 uF-25V; S3-22 uF-25V; S3-22 uF-25V; C5-0.47

Surely many would like to have a 5.1 audio system at home, but the prices for such amplifiers are often quite high. I’ll tell you how simple and not very expensive it is to assemble a 4-channel amplifier for such a system. After searching the Internet I chose

The amplifier is assembled on a TDA7262 chip, the power in stereo version is 35 Watt, and in mono version it is 80 Watt.

A DIY subwoofer is much cheaper and of better quality than Chinese models. And much more beautiful. . .
