I have a MK 4.70 that I am using temporarily for sub duty. I was running a set of components active on it, but had to switch over to use this until my zuki comes in. As a matter of fact - I fell that with two channels bridged - it is stronger than the JL 500.1 that I was running. I was going to put this in my wife's car, but I don't know if I'm going to do that. Let me know if you have any interest.
