It might do nothing, but it will not hurt. In your case with the amp pulling 1200+ watts on it's own it should help as the stock grounds were not meant to take that much power... as a result they heat up more and cause more resistance. That resistance lowers your voltage.

The ground on the engine that you circled is on the exhaust manifold. It is one of, if not, the hottest part of the car/engine. It is also separated from the engine block by a gasket and not the best place for electrical conductivity.

What does it say on the jacket? If that is kicker hyperflex it's tinned copper which is just copper with a tin coating to prevent corrosion. No drawbacks vs straight copper.

I would go with the hyperflex too. From the picture it looks like there is more copper than the other wire. It is also tinned to help prevent corrosion.

That is not true for DC. It is only true for AC power. See wikipedia: http://en.wikipedia.org/wiki/Alternating_current#Effects_at_high_frequencies

The top pair in the picture go to the tweeter. You can see the wire being run under the sticker and also in the diagram. http://kenwoodusa.com/UserFiles/File/Global/Consumer/Manuals/kfc-hq165.pdf They probably should not be run without a crossover. I am guessing that the tweeter and woofer...

Is there an existing switch on the breaker board for the stereo? If so wire the yellow(acc) to the breaker for it and the red(12v) right to the distribution block on the back of the panel (some would say to fuse or breaker this wire as well...). This will let the switch act like turning your...

With a boat you should always use marine grade cable. There is a lot of bad stuff in boats that will degrade a cheap wires jacket. Also, if you are installing these amps somewhere near the 12v panel there should be a common ground block there that you can ground the amps to.
