Well when we unknowing consumers purchase car audio products like amps the accessories are things that we often over look and so stores like CC will install inexpensive amps using the most expensive amp wiring kit, which are never on sell, I would have never choosen the amp wiring kit they chose for me because the sizes of are too large taking up all of the available running board space.
Dave are there some guidelines for
1) speaker wire guage (solid core or standed)
2) amp wire guage (solid core or stranded)
