Chill as a Cucumber
My friend tried to install my old system in his truck, but he didn't have any RCA's so he dug up some old av cables to use instead. We got the amp all setup and turning on, but the sub barely moves. I tried turning up the gain but It has to be almost all the way up to get it even close to what it was before. W'ere using the same wires that I used, same sub, same box, same amp. I'm almost sure he needs to buy some ACTUAL RCA's but I'm not sure.
