Review: If you are looking for a review that makes you pull the trigger on some excellent quality wiring , this is it. The quality of this kit is way above anything on the market. Don't cheap out on cheap wiring to save a few bucks. Thick ,True OFC, shipped fast. Running this on my Morel Ultimo 12. Customer service is great too ( Dan). I needed it by a particular date to get this installed and It was delivered in 2-3 days. The wiring literally has weight to it. Remember, You get what you pay for.
Review: I think these are the best, highest quality amp install cables you can get for the money. The flexible insulation makes routing them a breeze, the conductors are thick and high quality oxygen free copper. I only wish they offered multiple sets with options for longer or shorter ground and power leads. The terminals fit perfectly on my 24 Kia Niro 12v battery. Make sure you install the fuse properly and you’re golden.
