problem with factory sub amp for 01 Nav
I was wondering if anyone can help me here. I have an 01 Navigator with the Alpine sound system in it. One day my subwoofer quit working. I figured the amp was bad after checking that the 8" sub was still good. I removed the old amp and bought an alpine 200 watt mono amp to replace it and upgrade my system. Here's the part I'm having a problem with. I cut the wiring harness to the factory amp and used the hot(12volt) , ground, and remote(6.8volt?), so I figured the 2 wires left are the speaker wires. One of the wires has no voltage signal and the other is pushing 4 volts. Anyway, I cannot get any sound. My amp does come on, but sometimes takes a while. Is the factory gauge wire not big enough? do I need to ground the amp better? And why can't I receive any sound through the speaker wires? 5 wires,(hot, remote, ground, speaker +, and speaker - ? ) Please help before I take it to best buy. I know i'm missing something.

by the sounds of it you are not running any RCA's these wires are the ones that will carry the sound from the stereo to the amp. i personally would probally just re-run all new wires power, ground, remote, rca's, and speaker wires. good luck

thanks
I have a plug in on the amp to connect the speaker wires from the stereo without using the rca plug in's. I'm just wondering which wires running to the back are the wires for the original amp and why i can't get a signal by just plugging in the wires directly to the sub without going through the amp. The original wires from the factory stereo should have a signal, right? Maybe my wires have a short in them. Or maybe the channel from the back of the factory alpine stereo is broken. I'm not sure. No wiring diagrams that I have seen say anything about the wires to the sub-amp. Any more ideas? I'm lost.

I may have found out my problem. One of the speaker wires from the HU to the sub amp is not carrying a signal. Normally, each wire should carry a small amount of voltage, (around 5 volts). One is carrying a 4.85 volt reading and the other is 0.03 volts. I tested the wire for ohms from one end to the other and its fine. I'm getting the same reading out of the back of the stereo where the wires connect in. I think I have a blown channel in the stereo. Not a good thing. Let me know if I'm thinking right here.
