I parted my 06 auto out and took the double din and installed it in my new to me 04 6mt. I by passed the amp correctly on the auto and amp ,subwoofers worked(amp wire on grey harness to blue cable on harness).
Now that ive connected it to my 04 6mt i had to tap into the blue harness amp wire with the amp wire coming from the grey harness. i got my sound on that way again but my subwoofer isnt working so im getting no beats and my music is so WACK. i need to get a new amp? subwoofer?? or maybe shouldnt have tapped into the amp wire from the blue harness?? any advice will help !! TIA
