I have a kenwood kdc-6011 (yeah I know its older) and its been working fine, I just hooked up my new set of amps and subs, and now I can hear music if its on tuner, but when I switch to CD, the CD spins, and displays the song name and counts track time like its playing, but I dont get any audio.... I need help answering why this may be happening.... any and all comments welcome PS. I had it hooked up earlier with the mids running off the deck and the subs through the amp and i could play CDs.... I dont know what changed..
