    • Used for the Big 3 Upgrade
Color: Blue/Black
Almost had enough for the big 4. It's held up for many years for me. One thing to note is that GoofOff and maybe other alcohol based cleaners will take off the white lettering on the cables, but they also clean it really well. I didn't experience any crazy voltage increase with it, but supposedly it does help under load, maybe especially since I upgraded to 2 2200 W SoundQubed amplifiers. ... show more
