I was impressed with the receipt of this installation kit from Skar Audio. I was a bit surprised that a previous reviewer indicated that there was some aluminum in the OFC cables. I have OCA 1/0 cable where the aluminum is clearly visible when viewing the cut angle of the cable. With the Skar 1/0 OFC cables, I can't see any presence of OCA / aluminum in my cables. My only gripe? The included RCA were a bit basic and not too exciting. However, I have a set of 16' RCA cables that I purchased separately and have stayed with through the various installs of gear in my car. The Skar RCA cables are not being utilized, so I can't make a comment regarding their quality for audio, grip on the RCA terminals, etc.

Wires not full copper some aluminum in there too which is rather misleading. Going to rewire in a few months.

So far so good product came on time and customer service representatives were helpful they made sure everything was right

I was a tad sceptical when purchasing this because the prices for a true OFC wire are so expensive. When I receive the package I was very impressed with the quality of the kit. My audio shop will continue stocking and selling this stuff. Great job again Skar Audio!

Good iyems
