I just hooked up my amp to my subs and everything, and the amp isn't getting any power. At first I thought that it was no good, then I got to looking and messing around. Everything is correct, HOWEVER I believe now that I missed something along the way. Checked fuses, checked ground, etc. Then it hit me. I saw a REM power slot (my old amp didn't have one) with which I wasn't familiar with. The cable from the battery goes into the 12 v spot, but what goes in the rem slot, and what does it connect to?
