Hey guys I'm new here, but I've been screwing with this setup for a long time. The setup I have is 2 Pioneer 10's, a brand new Pioneer head unit with dedicated sub outputs, and a brand new 800 Watt Dual amp. Now, the power/ground/remote cables are brand new, the head unit is brand new, as well as the amp. I have had this identical setup in a couple other vehicles before this one and they have all worked fine. But I can get no sound to the subs. We have adjusted the sub settings on the head unit, the sub is set to be used, we have tested every possible thing with a voltage meter and everything has power. We have changed speaker wires, we pulled the subs out and made sure nothing was wrong and there and everything was perfect. I, and the others helping me, have no idea what to do.. Any suggestions/tips/help? All is appreciated, thank you!
