Ok so I love my tunes and hate it when I don't know if it is working. This has got to be the most confusing system I have seen. I can't here anything coming from the two deck speakers in the back. The 6x9's that say kenwood on them. I can't tell if the sub is on and I don't know it the amp is working properly as there are no lights lit on the amp like usual. I know everyone is going to laugh and I read the long post about the sub not being on. I have been messing with the radio all day. Any guidance would be much appreciated. Oh yeah this board rocks. If it was not for this board I would have disconnected the battery to have the head unit come back out. Thanks in advance.
