The big 3 helps a lot. I just recently bought an amp from someone on here and I could not turn it loud for nothing. It would hit hard then drop and sound shitty as hell. Now after I did the big 3 with 0/1, I was able to turn it full blast with no cut outs or anything. It's worth it man. It's a definite must. Get a battery too while you're at it, I am, then the alternator. BTW, scottiej is selling big 3 kits cheap in for sale section. I got my wire from him. Good guy there.
