Ok, what the **** did I do wrong? I just replaced my RCA's thinking that was the cause of my ground noise. It wasn't though I found the cause.
Now the sub is playing the engine literally. When the engine is off it plays with no issues, when its on you can hear and feel the engine through the sub. It doesn't increase when I press the gas. I didn't have this problem with the other RCA's and the new RCA's are better. The only thing I replaced was the RCA's, remove the bullet fan and add the bass knob. I went from a memphis 6 channel RCA to 3 2 channel Stinger level 3's. I tried one of the other sets that I installed and it does the same thing.
Could it be a ground and just am hearing it cause the RCA's are better? Pinch an RCA somewhere? What do I need to do to fix it?
