I worked as a professional car audio installer for 4 years, and there is a lot of truth to the larger wire with more strands in it making your amp perform better, but the problem is caused because your alternator cannot supply enough current to your amp. True, your amp may sound better with a bigger wire, but this won't solve the lights dimming problem.
You absolutely need to either A) go with a bigger alternator, or B) (my suggestion) go with a 1 FARAD Lightning cap or if you just have a small amp, even a .5 FARAD capacitor would probably do the trick. The capacitor stores energy during lower moments of consumption by the amp, and when the amp requires an instantaneous boost (a big bass hit) it will get it immediately from the cap.
You will be happily suprised if you do this. Go by a stereo dealer and ask them what they think and see if they have one you can demo for a couple days. You will quickly understand.
Expect them to go for between 70-250 dollars. Here is a link that might help, althought with a little searching, you can get them cheaper elsewhere.
