Found out that this is not available and discontinued. That is why the low rating. I did find out that the UR1 is the universal remote for the Nano amps so I ordered one from Onlinecarstereo.com so I hope it works. I plan on using the NX3 to power a pair of Kenwood seperates (the 709s and 509s) off the high side and four Summo 64 subs. wish me luck!
