I suggested the wallyworld stuff because it is cheap and yes it is not as good as other brands, however it is great to get a good set of amp wires i am not argueing that... but what about the amp its self? Some amp are not going to be easy putting 4 gauge wire in if they are designed for 8 gauge. I do understand that you can cut someof the wire off but its not a very clean end product and, with bigger gauge wire there is bond to be some split ends and neg plus positive= broke amp with 4 gauge wire

. Just my .02$
