[QUOTE="Elvenking, post: 8267248, member: 661211"] Thank you immensely for the questions. Do you use time alignment? I am trying to determine if my head unit has time alignment as of last night....just about to go out there now and see if it is tweakable with my deck. I feel this would be a great adjustment! Have you level matched? Not sure what is meant by this. Please educate me. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] If you mean matching the levels of the amps, then yes...as good as possible. I didn't see any reason to adjust L/R levels due to the fact that will create a single listening point. Have you used band limited pink noise? I have used both pink noise to get initially flat, and then a sine generator to kill exaggerated freqs. What are your crossover points and slopes?

Where are your speakers installed and how are their mounting locations treated? Locations are treated with heavy Dynamat and mounted with 6.5 in lower foot area of door...factory location.

Is your entire system wired in stereo? Comps are in stereo and the bass is mono. [/QUOTE]
