Hello all, i have a question about the rkl...so i bought the unit for a good price, it came with a pb4 bar and a pc4 bar, the pb4 bar when connected to the power supply the lights come on and the plugs work, on the other hand when i do the same with the pc4 it doesn't do nothing. I got another pc4 bar and the same thing happens, my luck can't be that bad lol, does this means the bars are bad? Thanks
