I'm guessing it's the deck as well. My Awia deck works fine, it gives out sounds through the speakers, but it doesn't have enough power to run my amp and subs, but the Pioneer does. Weird thing... my Awia deck gives out sound, but doesn't have enough power for the subs. The Pioneer deck doesn't give out sound, but gives out power for the sub to hit. I've messed with the menu and nothing worked. Before I received the Pioneer deck, it worked fine in my friends Accord, I'm hoping it's the decks harness has a loose wire or something so I can get it replaced because I like the deck, it's sleak and it has a nice layout, but some people may think otherwise.
