I haven't put anything in my car back together yet cause I don't think Etronics shipped off my amp yet. But I wanna program my 2 MRD-M501's. When doing this, should I program how the manual tells me? This is getting a little off topic. I just wanna know if this is good or bad. I have a 18 foot power cable from my Distortion Block to my battery and then I have 1.5 feet from my distortion block to each amp. And was wondering if the voltage should be at 14.1 with that length of power cable. The lowest it got was 13.8 volts.
