I had a local audio install shop install an Xtant amp + ID sub in 03 MDX. When first installed, head unit had to be turned on and off 5-10 times before sub would kick in and start playing. Remote turn on always had 12.3+ volts, and all lights displayed on amp, but would still only power sub after several shut down and turn ons of factory head unit.
Sent amp back to Xtant for factory refurbish.
I reinstalled amp, and now it won't power the sub at all!!? I've turned it on and off a couple of hundred times. Still plenty of volts to remote turn on. Input sensitivy is set to lowests level (this is adjustable on Xtant Amps).
Is it possible that I don't have enough volts coming in from input speaker wire for amp to process? I'm still using the factory head unit, and just spliced into rear speaker wires as unit doesn't have a pre-amp sub output.
