I had 1500 dollars worth of Cheetah laying around when my Sub Utopia arrived, so I used it until I could order the correct length sub cable from AQ. They have their own ideas here and it WORKS!! Sub-1 or Sub-3, it is up to you, I am a DBS fan because I have systems in the garage and in my shop that might not be used for weeks at a time. These cables are very affordable which is good because they don't seem to come up on the gon. Z.
