ok. sorry if people have already said stuff about this, but i just did it, and felt like writing about it.
my lights kept dimming w/ a kenwood 8101D amp pushing 400W RMS @ 2 OHMs, running a rockford fosgate HE2. 400W did not seem like that much power to be making the headlights dim, so i decided to get an optima red top battery @ autozone tonite @ 2am. i got the one 750 cranking amp, i think... runs for $109 w/ an $8 core charge. i had just bought some 4AWG ground cable, to ground my cap, since it was dimming.... i didnt ground my amp, so i remembered people saying how "this bomb ass ground kit will increase hp, blah blah blah" at the same time, i noticed that my negative cable wasn't even bolted to the chassis w/ that connector about 5" from it! sounded like the perfect time to do it.... i filed down a spot on the side of the engine bay, and grounded it there, connecting the stock connector w/ the other end of the 4AWG ground cable.
i took it for a test drive right now, it worked great..... listening to big booty music @ full blast, she doesn't even flinch. even sitting at a stop, the tach only moves maybe 500-1000 RPM w/ the stereo pumpin. so, if anyone is wondering about either of these two things (grounding or red top) they work. i would have tested it w/ the old battery to see if the ground was the most effective piece, but it's 4am, and i dont feel like pulling it out, and driving all the way out of the neighborhood again.

well, each line on the tach is 1000 RPM right? the needle moves just slightly, never move than one whole line. so, i said 500-1000. cuz it does move a little bit
