I am new to outlaw products so i hope you all will bear with me!I have a 990 and all 2200 monos on my system,the two channel stereo mode has a very strange sound,at times sounds like echo or slight reverb and other times a breathing effect. At this time i just wanted to configure stereo as i havent finished rear channel speakers but i need to address these sound issues first. Youre help here would be great, thanks
