Ok,
I have a kenwood HU, model KDC-X689, and an Alpine amp, model MRD-M300. When I turn the subs on through the HU, they will play with the tuner but not with a cd/mp3 disk. I have tried toggling the subs on and off while the disk is playing but still nothing.
What would be the cause of this? Is it and amp or hu setting that I am missing? Any help would be great.
Also, if anyone has had much experience with the MRD-M300, or MRD-M500 amps, could you please give me some advice on where to set all the settings. I haven't the slightest idea.
