sorry my phone cut off your post and pictures there.
it will be fine. It's a very small resistive load. You box should specify a maximum input wattage, it's likely below the output of the Rowe amp, but check to be sure.
if you only have output on one side after properly wiring up the speakers, check your screws where the volume control is attached and make sure they are still tight. if still nothing, check the plugs on the amp and make sure they are connected tight. The volume attaches with a plug with about 5 or 6 wires on it...white and purple or purple stripe i think.
if not, you might have a blown channel...take the amp out and flip it around... there will be some fuses back in there on the boards.
if you have some burned out, your channel is blown
