I have had a few Soundstream Amps over the years and was always impressed by their rock solid stability. They always seemed so bullitproof to me. I still have a Soundstream 2 channel amp that I bought back in 1993 that is functional.
I am currently running a SOUNDSTREAM RUBICON RUB300-2 for my one 10 inch MTX subwoofer in a Thunderform box. It's puts out more power than I need and I find myself scaling the gains and input levels back.
Dunno bout the woofers, but I really like the amps. Good Luck.
