assuming that the 8ga. wire is fuse correctly, upgrading will not improve anything related to safety and will barely improve anything else. you might see a .1-.3 volt drop along the line, but thats not going to produce an audible difference. out of curiosity..what amp?
edit: duh...i forgot about your other post. that kenwood amp puts out 460 watts RMS...so...
460watts/12amps=38.3amps at peak. however...taking into account the efficiency of that amp, the draw is more like 60-70amps. BUT...thats only with sine waves and the like, not musical passages. you will probably average around a 15amp draw with peaks at 30. assuming the fuse (on the wire) doesnt blow, you are fine. as for your question in the other thread...you alternator will be fine. i used to run 1800+ watts of class a/b power in my eclipse and it took several years for that to kill the alt, lol.
