Review: Durable - Cheaper and better quality than buying from store. They are tinned coated which makes them very durable. I used them on my boat, which gets very frequent saltwater use. I have been in rough seas and wires have not failed me at all. Definitely recommend
Review: Excellent marine rated speaker wire - Used this installing my Uncle's JL Audio speakers powered by Arc Audio amps. Used the 14/2 AWG for the 6.5" speakers. The quality of this wire is top notch and would strongly recommend it. Sounds great!
