The sound quality is way better in my empty dash. The foam compresses easily, allowing it to be a quick install. A quick trim with scissors and it fit great.
1x DA47 Single Power Supply Portable HIFI Headphone Amplifier PCB AMP DIY Kit

Great kit, would recommend for general use applications
Resistors only color labeled. Some interference at about half volume, minimal at full volume which is fine for my application. Great board design. Volume knob interfered with casing and required slight modification. One OP-Amp socket malformed on single pin. Capacitors fit in case. Great packaging.
