I run 2 Alpine PDX amps ...4x150=150 rms @ 2,3,or 4 ohms.The sub amp is PDX 1000.1...1000+ rms @1,2,3,or4 ohm stable.Alpine amps are not 1 ohm stable.They are CEA rated and have a excellent ,clear sound.Very loud,very clean....Pricey,small footprint and stackable.I like them....Alpine50

SO PDX's are d Class?

I'm gonna have to look into those...
