The existing aftermarket head unit is not functioning well and I have determined that it's the actual HU which is malfunctioning. While diagnosing the system in the car I observed that the fader was not working. However, I'm wondering if one or more of the following might be true.
a) The rear speakers are not a separate REAR channel from the amp, but rather just crossovers using the FRONT channel. This would mean that fading to the REAR using the HU wouldn't produce any sound.
b) The amplifier has a blown rear channel.
c) The HU has a blown rear channel or other electrical malady (it definitely has more than a FEW issues, so this wouldn't surprise me.)
Can anyone verify that the behind seat speakers are full range speakers? And if so, are you able to use the fader on your HU? (I don't know what the capabilities of the stock Bose HU are, so maybe this is just an aftermarket question. Please note what your HU is when replying.)
Thanks to any info you can provide!
