The addiction continues...

Hello All,
I've been playing with audio since I was a young kid. It's been unshakeable addiction ever since. I also started a small production company about 12 years ago that offers sound, lighting and video services. Right now my audio focus is on car audio. I started building my system about a year ago. Some nice focal speakers up front, Hertz in the rear and JL subs and amp for the lows. At the heart of the system is a DBX Driverack PA2 that's been modified to run on 12v. With the addition of the Hertz I will be needing to add at least one more DSP channel (Focal's use four channels) and am about to start down the road of SigmaStudio compatible processors
