i don't really know or care about the memphis rca cables as big said if you route it away from your power line the interference is about the same. I just LOVE their power wire, it supper flexible thanks to the softer coating, and has a huge strand count meaning more surface area to carry more power, I have used the 8 gauge wire kit for 500 watt rms systems and doesn't get hot. The fuse block is a nice piece too it uses a medium size blade fuse instead of those torpedo fuse holders (i had 3 of those POS and they all cracked with the cold weather up here which lexan loves to do one caused a bad short when it broke and killed a battery)

That would actually be vipor that said it but I keep the power wire and rca's on oposite sides of the car.
