I am looking to boost my pre-out voltage off my deck with this unit, it is currently 4-5 volts and I was wondering if anyone has used AudioControl's 6 channel line drivers. I am doing this so that my amplifiers (Sundown 1200, Sundown 100.4) do not have to work as hard to get the same out put. When I was using my bass expander or reconstruction processor my electrical system didn't struggle nearly as much because I could turn my gain way down and I got more sound for the limited power that I have. I took the bass expander out because I didn't like my bass reconstructed I like the natural bass which I hope to keep with the line driver. Any thoughts?
