New guy here. Installed Kenwood DDX7701HD unit and I have lost right side speakers. Used Metra Axxess TYTO-1 harness along with ASWC-1. Also had bad battery cell and replaced battery. I get plenty of sound from drivers area but when I adjust balance to right there is no sound at all there. At this point my ASWC-1 cycles through but isn't recognizing radio. That issue can wait unless it is part of this issue. Any help will be appreciated as I don't have a lot of hair left to pull out.

 

Try your fader - does it work?

Factory amp splits signals for front and rear, but only receives left and right from the stereo head unit. Also, I am pretty sure you need the ADBOX1 if you want to use the factory amp...

 

When I fade to right sound goes really low in left but none on right. I do have sound from left front and rear. Fade to rear just lowers volume on front left. (this is the premium system not ML). I will look into Adbox1 although not really sure if that will affect amp. I am wired to amp turn on wire from radio and using 4 rca connections .

 

ADBOX1 will totally affect the amp; it's what you need to be able to get four channels out of your system. The amp only wants a left and right signal, the ADBOX allows for that. Search here in this forum because there are a few really good threads on this.

 

Turns out the TYTO-1 was defective. Carried it to Sound Station and they used a different connector and a new box and it worked fine.
