Great product for car audio

Not bulky with a great sound. Absolutely zero "hum" when installed properly. Very easy to hide.

crystal clear

i could tell the difference in the high's when i switched to these cables, they are a little long i originally wanted the 17ft ones but they were out of stock, i actually had to turn the gain on my amp down a hair because it was that much of an improvement
