Hello, my current speaker set up includes Infinity Kappa 6.5" components front, Infinity Kappa 6.5" 3way rears, 1 Kenwood Excelon 12" shallow sub. I want to upgrade the current amps I have(Rockford P4004 (50x4) front/rear and Rockford P3002 (300x1) for the sub. So far I have looked at Hifonics ZXI6406 (85x4) and Hifonics 1206d (450x1) and an Audiobahn A6601T (75x6). Does anyone have any info on these amps? What other amp options do I have here? Thanks for your help
