I think the Comp VR's are pretty efficeint,not needing a lot of wattage to run,I USED to have Audiobahn and as far as looks,they were great,but i was alittle dissapointed on the actual power output of them,I had a 6 ch and a monoblock d class,I switched with a brand that i worked for and it was A LOT better for A LOT less,but the Audiobahn should be good for you
