Hi guys, I am currently trying to decide between two amps, the Soundstream Van Gogh 320.4 (80W RMS x 4 into 4 ohm with 115db S/N) and the Audiobahn DUB5004 (75W RMS x 4 into 4 ohm with 100db S/N). I require two such amps, one for me and one for my bro. My bro is running two JL dual voice coil subs (2 ohms each coil) and rear 6x9’s. I am running front 3 way Pioneers and Hertz high energy HCX690 6x9’s in the rear. I want an amp that is powerful but that is totally crystal clear in clarity. My hertz are currently off my deck (100db S/N) Sony and they sound amazing and don’t want to lose that clarity and depth of sound. Which of the two would you all recommend? Any advise would be greatly appreciated. Thanks.
