I have a 2007 X2 as well and my speakers don't sound as nice as I expected them too. I just have the standard JL's with only 2 tower speakers. I just have the single amp that came with the boat. I am wondering if I have it set up wrong (like the settings on the amp)...? Wondering you if could lend some advice?
Just wondering what each of the amp settings should be. I'm only using channels 1-4 of the 6 but I wasn't the one who set this up so I don't know which speakers are in which channels. I have two which plugs in the top channels (1 and 3) and two red plugs into the bottom (2 and 4).
Also I'm not sure what each of the settings are on the amp:
Filter Mode (Off, HP, LP)
Input Sens screw
Input Mode (Sum, Discrete)
Filter Freq (50-200 hz)
Input Voltage (Low, High)
Any help would be greatly appreciated! It almost sounds like all the speakers are blown, but I don't think that is the case. I have pictures of the amp settings as they are currently (just didn't know how to attach those in the MC message).
