A couple years ago my Hifonics amp went to hell and I was looking for a replacement. I searched around and realized that the Sundown SAE 1200D was what I was looking for to power my 12" Fi BL and came here to purchase it. Was content for about a year with what I had until a car fire took it all except my amp (only thing I removed as it was installed near the rear hatch in my blazer). after that bad luck and some financial issues, I am back and reading the forums all I can so I can get another daily system going.
