[QUOTE="n2audio, post: 8387965, member: 540940"] I don't understand this comment I would like to refute it in an effort to keep OP from undoing something that is not likely causing any problems. A decent LOC can provide a perfectly clean (high voltage) signal to the amps, and IME is not difficult to install and tune with an acceptable degree of accuracy. I think the LC2i settings are too high and the Pio amp gain is too high on top of it. Speaker levels in this car are what -- 30-50w per speaker? If that's at 4 ohms that could be 10+v coming in. I'm not sure how the lc2i deals with high voltage input - apparently it drops it down to nothing and adds is own gain. Even so, if the master dial is relatively linear it looks like it's set in the 6v range with some degree of bass boost. Hard to tell whether the Pio is set at ~9:30 (~4v) or 3:30 (~1v) -- too high, or way too high, respectively. And the bass settings just complicate the situation. I don't think there's anything wrong with the install as a whole, I just think the settings are jacked. With that processor you should be able to get all the gain you need with the amp set at its min (6.5v). If you have to turn the amp gain up at all to get ~35v there's a problem upstream. One last thing -- I think the 1250w rating on the sub is optimistic. Not saying it "can't handle" that much power, but that you need to be careful with it if you're going to run that much. And the way things are tuned at the moment I think it's getting abused. [/QUOTE]
