So here is the dilemma, I have the Rubicon 450s ordered and will be here in a couple weeks. But I am wondering what I need to run them. I have went through all the past posts, and here is what I came up with: PPI DCX 1000.4 4-CHANNEL DCX AMPLIFIER Does this make sense? Can I get away with something smaller and cheaper? If so what difference will I see with something smaller? Thanks!! Specs are below. Power @ 4 Ohms: 125 Watts x 4 Power @ 2 Ohms: 250 Watts x 4 Mono Operation: 500 Watts x 2 @ 4 Ohms Fully regulated design for guaranteed power delivery Flexible TC-X crossover with configurable line out High-voltage input capability with selectable 12dB attenuation Mixed mono/stereo operation 2 ohm stereo stable Q BASS™ Plus THD+N: 0.08% S/N Ratio: >100dB Freq.
