Hello Friends, I made a 200W mono amplifier in this post. using 2 pairs of 2SC5200 and 2SA1943 Transistors, which can deliver up to 160W RMS output at 4Ω ±35V. The low-mid frequencies of this amplifier are very good. And other frequencies are decent. You can use this amplifier for a subwoofer using a low-pass filter. Overall, the sound quality of this amplifier is decent.
