Hello Friends, I make a 100W subwoofer amplifier in this post using 2SC5200 and 2SA1943 Transistors, which can deliver up to 100W RMS output at 4Ω ±30V. For the low-pass filter of this amplifier, I have used the 4558D IC. This is a subwoofer amplifier. So, for that, you will connect the subwoofer only, and you can hear the low frequency. Overall, the sound quality of this amplifier is excellent. If you make this amplifier, you will not be disappointed. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to PCBWay for manufacturing my PCB. PCBWay are the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil and PCB Assembly Service. Here you get, 100x100mm 2 Layer PCB only at $5, And processing time within 24 hours. And they distribute, worldwide. The more you order, the less price you have to pay.
The PCBWay 11th Badge Design Contest celebrates PCBWay's 11-year journey of innovation and excellence. Themed "11 Years of Innovation and Beyond with PCBWay," the contest invites designers, makers, and visionaries to create badges that honor the company's legacy while envisioning its future.
Design Requirements:
Incorporation of "PCBWay" and "11": The badge must feature both the company name "PCBWay" and the number "11."
Creative Techniques: Designs that utilize PCB, PCB combined with SMT/THT, or PCB with 3D printing techniques are encouraged to achieve functional and visually appealing results.
Concept Explanation: Submit a brief description detailing your design concept, including what PCBWay represents to you, the message your badge conveys, and the significance behind your design. This explanation is crucial for the judging process.
Timeline:
Contest Opens: March 3, 2025
Submission Deadline: April 30, 2025
Winner Announcement: June 12, 2025
Winning and notable designs may be showcased on PCBWay's official channels and could become the official PCBWay 11th badge.

Testing Method After Complete This Amplifier
Series light test:- After complete this board don't forget to series light test. When you will on this amplifier via series light, it glow for some time (1 - 2 sec). Then series light will turned off fully. If the series light will fully turned off, then check the voltages.
Check Voltages:- Bias volt 0.5V to 0.7V. Check Speaker Output and Audio Input voltage. Here you get no voltages 0.00V. If you get same voltages, then connect preamplifier to input and connect speaker to output.
Power Supply:- Recommended transformer 30-0-30V 5A.
