Front door speakers not working

[Walkercraig01]

I just bought a 99 Yukon sle . And this is my third Yukon and first without Bose . So it has an aftermarket head unit . But the rear 4x10s work and the rear doors . But the front doors did not . I have a DVD player under the front passenger seat but nothing under the drivers seat . I can’t find another amp so could it be just the head unit it powering the rears ? And not the front doors .

Did you check the wiring? Are they wired correctly? Or could've been an amp to the front speakers, and they removed it before selling, and didn't connect the wiring. You find some weird stuff done to used vehicles.

There isn’t a power wire or signs of a amp. But also the passenger door electrical none of it works right now . The window will roll up from drivers side so I’m guessing maybe it’s disconnected somewhere
