speakers in the doors

[just-n-time]

I have finely gotten a new after market radio to work and have the wires to the speakers done and bypassed the fader, now I am trying to get those door speakers to work I have a factory power unit in the trunk and it has not been bypassed, yet the door speakers are not working. Can any one help me with this part?

Not sure I can help with a solution but I have a few questions.

What radio did you install?

Does it have its own built in amp or is it a preamp unit?

Are you wired from the radio to the MB amp in the trunk then to the speakers?

I have always replaced the amp when I replace the radio. So not sure if an aftermarket radio will work with the MB amp.

Have you checked the wiring for continuity with a circuit tester?
