I'm trying to decide between two different amps from Audiobahn. Either the A8000T (mono) or the A8002T (2 channel). I'm going to hook it up to 2, maybe 1 AW1206T in a small sealed box (between .5 - 1.0 cubic ft). Another question... Will one amp be enough? Newby question... Is there any advantage to having a mono amp vs. a 2 Channel amp and vic versa; If I have 1 sub? If I have 2?
