So i recently purchased a 92 Mercedes 300e as my first car but the head unit did not work. i decided to get an aftermarket alpine x200 but i have hit many problems with the install. i have the wiring harness connected and i beleive all of the ground wires correct. I was told the speakers are 2 channel ( not sure if this is the correct term but the way i wired it was the front and back speakers are wired together for both sides.) but im not sure if i did that right.
the head unit came on but the speaker would only play out of the 2 speakers in the dash but none of the side or back speakers.
does this have to do with the amp?
should i disconnect the amp and it would work?
can the speakers in the car be powered by the head unit for the time being before i completely rewire it?
