Hey, I'm in the middle of my install. Im putting in 2 cadence amps, a 12" type r and some pg rsd65cs comps. Right now I'm just trying to get the sub working first. I have the amps set up with a distribution block and when my head unit turns on, both amps are getting power (the LED power light comes on). However, the sub is not playing at all. What are some of the typical problems that may cause this. I double checked all my wiring... Sorry if this is something I should have searched for, wasn't sure what I should type in when searching. Thanks!
