sony stuff is crap IMO. Especially their "cheaper" stuff. And I did run a dual amp but one thing i made sure to do was buy one rated for twice as much power as what i needed. I believe they rate their amps higher than what they actually do, one way i have to prove this is with the HU volume at max, and amp gain at 12 db (max) there was only a couple of hard hitting songs that sounded distorted. Of course i didn't leave it there, i was testing it to see if my thoughts were right. Dunno what you have to say about that matt
