I just purchased a 2010 Axis A22 and found that the sound system isn't working properly. Here is what is sounds like; http://youtu.be/-RHBux8es5E
I did try to unplug the RCA cables in the AMP and bypass from RCA to AUX to my Iphone and it works great! At this point I'm thinking that it's a short, bad ground, bad cable... but no clue where else to start. We know that everything after the AMP example wires and speakers are fine - it's between the AMP and DECK. But what?
Let me know
