Hallo everybody, here Gianluca from Italy, Sound engineer (mostly live) with an electronic passion! I have a small personal lab where I try to fix stuff for me and for friends, and where I build some audio effects. Actually I've realized I have several friends with Sunfire subwoofers...this is why I'm here!

After servicing quite a few Sunfires, I've noticed their shortcomings as well as areas which can be improved. I am currently working on a relatively universal upgrade for Sunfire AMPs. The upgrade will include updates to the amplifier circuits and tracking down converter for more power, better durability and much better soundstage.
