***If installing multiple amplifiers, or using a 5 channel amplifier that doesn't have internal summing for the subwoofer channel (needs a dedicated subwoofer input only), you may need an RCA splitter(s) if ordering a 4 channel LOC kit.

      So simple

      I tried so many other options and non worked. I reached out to them and they responded and told me what I needed. I ordered it and it came with in 5 days of me ordering it (I ordered Friday and got it Wednesday) sounds great and so simple with easy to understand instructions.
