I bought the Audiobytes and EP125 in late January. So they're just over two months.
I did call as soon as I noticed the backward wiring, and they did offer to send me a new one. I told him not to worry about it - I just switched the wires, but I wanted someone to know that there were QC issues. I imagine it's somebody's job there to test the amp and, ostensibly, prevent exactly that sort of mistake from shipping to a customer.
But now with the sub... I don't feel so forgiving. I left a message with Axiom. I'll let everyone know what comes of it!
BTW - despite this, I have been quite satisfied with the sound quality
