Perfect for my DIY project! I built a small bookshelf speaker for my study, and this module is exactly what I needed. The wide DC 8-18V input range is very convenient - I can power it with an old laptop charger. Sound is clear and crisp, no distortion at normal listening levels. It's compact and easy to wire, even for a beginner like me. Great product at a great price, arrived in Australia in 10 days.
