I got a Kicker 2 channel amp that I want to bridge to one sub. The left speaker output works good. The right speaker output is not working. I hooked up the sub to just the right output to mess around with it. I adjusted the gain thinking that could be the problem, but it made no difference. I have RCA's running from both jacks in back of my H/U and tried every combination trying to make it work. I went and got an adapter to bring 2 into 1, but I couldn't figure it out. Also, I have the white jack from the H/U to white on amp and red to red, but red from H/U will power white on amp. I know this sounds confusing but I really would appreciate a little help. Thanks in advance.

 

You could have easily blown one channel. And yes your paragraph is relativly confusing.

 

Is there anything I can try to be sure? When I bridge the pos. right to the neg. left it works fine

 

try switching the red rca into the white and see if the input to the amp is bad. Otherwise take it to a local shop and have them bench test it to be sure.
