Krystal Kable 4 Channel 6M Twisted Pair RCA Cable 20'

I had an annoying alternator whine and almost everyone told me it was a bad ground.I tested many ground points and none seemed to fix the issue, so I decided to test my equipment one by one. Ended up being the somewhat cheap RCAs I had installed (shame on me). This Krystal Kable is considerably more expensive than others, but it sure did fix my issue.

If you want some good shielded cables these are it. I noticed clearer sound right from the go. I have two sets of the 4ch cables run in my car. One to my 5ch amp & one to my mono block sub amp. I also got some female to female RCA connectors & a small 1ft RCA cable to make the 5th ch work.

Fit tight round the terminals for an extremely secure fit. Competition Show look. KnuConcepts has a lot of great high quality car audio accessories that are extremely high end at an amazing price.

There’s a lot of RCAs on the market and decided to give this one a shot and couldn’t be happier with the quality and results!

Had engine noise after I installed new amp i installed these and no noise at all they are a little pricey but wroth the money

These rcas are definitely worth the price. They grip tight, no worries about them being tugged out. Solid sheathing on the outside of the rcas as well. I owned a bunch of their rca products and use the wire in my build. Some of the best looking and best functioning on the market. Rcas are thick AF.

Installed a system (two amps, sub, and 6 speakers) into my car last July. The install went well and I used Rockford Fosgate RCA's that came in my kit. Started to have some issues with my right front speaker, crackling, popping, worked as an installer for years and knew that it wasn't the speaker. Long story short the Rockford RCA's had slipped off, there was nothing to hold them onto the jack. I have used Knu-Konceptz's power wires for a friend’s car and while I was being cheap and trying to keep my personal costs down in the end you get what you pay for. These RCA cables were a lot easier to run as they were the 4 to 1 design couple that with the 2 channel set and you have just 2 thicker wires to run. The problem I was having with my right front speaker is gone (over a month ago) and hasn't come back, these RCA's hold well onto your amps and head unit and give enough insulation. Will use these now for future jobs and again you get what you pay for.

Very high quality product
