Using it with the Dehum kit. It gets loud, and it's easy to install. Also using the original speaker, but put longer wires on it to make it easier to open and close the shell. At least for me it was made easier.

Installed with dehumm dehiss module and IPS upgrade. As with all the other CleanAmps I've used before it's a decent volume upgrade without distortion at high volumes. No complaints, works great.

This and the de-hum and hiss kit sold do an awesome job really cranking the volume up on the neo geo and giving you some awesome sound.

Just got in the mail. Installed it. Great sound. Don't know if I'll play it at full volume just because of battery but hopefully rechargable battery would come next. It's good it's worth it.
