[QUOTE="knil, post: 8441236, member: 667746"] Ah, now I understand what you mean by the big 3. I have done a modified version of what you are calling the big 3. I replaced the factory wire between the engine block and chassis with a piece of the 4 gauge wire and I believe I replaced the factory wire between the negative terminal of the battery and chassis with a 4 gauge wire. I haven't done anything modifications with the one you describe between the battery and engine block. I will take your advice and double up on those 3 connection points. I drive a 2008 Honda Civic and I believe it's alternator may be rated around 100 amps. I am in the same thought camp as you about this being a power related issue, especially since I am now driving that kicker amp at 2 ohms instead of at 4 ohms. I did take a look at the connections between the amps and the power distribution blocks and everything looked tight.
