Ive been told thicker wire is better, and that you should use gold connections for best sound quality but unless you are a pro you wont know the dif. Just dont use solder conections, they dont hold up with the moisture and vibration. lots of diferent ways to do car audio, just keep in mined rms is more importent than wats and clarity is even more importent. 6x9's suck but work when you cant fit anything else. highly recomend components over 2 or 3 ways. and I agree on crutchfield being a good place to deal with for car audio. and nothing hits harder than a JL sub.
