Can you mount the amp outside, I have a pair of AP650 and RSUB 300 subwoofer on my deck it is hooked up to my house Amp , I would love to have it to a separate Amp what do recommend
The Nero would not be considered for outdoor duty but could be used close to your home amp which has a wire coming from the outside already. You should also consider adding an dedicated Subwoofer amplifier (like our SMP250) that would be connected to the sub out of the NERO and in fact features a variable output so the Master Volume control on the front and Remote control controls the volume level of the speaker outputs as well as the sub out. You could also run a IR receiver kit so you could use you remote control outside as well.

I see the amplifier has a sub out does volume go up and down on the sub when you turn the main volume up and down . Right now I have a 200 watt mini Pyle Amp I got the sub plug in but when I turn down the main volume the sub does not turn down with the main volume. Before your amp I would to know.
You are in luck, the NERO 's Sub Out is variable so it is controls the volume with the master Volume Knob on the front panel for all inputs including Bluetooth, Aux in, Fiber Optic and Unbalanced RCA (R&L). Add to that it is 4 ohm stable so you can connect 2 pair of 8 ohm speakers.

from Thompsons Station, TN asked:
February 16, 2018
Is there a setting for 4 ohm or 8 ohm resistance, or does the receiver automatically sense and adjust?
The Unit is rated to go down to 4 ohm which means you can connect two pair of 8 ohm speakers in parallel or a single pair of 4 ohm and of course a single pair of 8 ohm. It automatically attempts to deliver the load based upon what you connect to it. It does feature a 16-24 bit internal DAC and multiple inputs.
