[QUOTE="Brian Owens, post: 1216580, member: 548450"] Don't give up yet!!! Here is the owner's manual on line: [URL="http://www.orioncaraudio.de/pdf/G47400_05_10_2-03.pdf"]http://www.orioncaraudio.de/pdf/G47400_05_10_2-03.pdf[/URL] If it was me, I would start with your HU crossover settings turned off so you can see what the amplifier is doing. I would start with the amp settings: Low pass set to "12" and the frequency all the way up to 250 Hz. High pass set to "24" and the frequency all the way down to 10 Hz. IntelliQ set to 0. I would guess it can stay there. You will not need boost in this setup. With a moderate volume level, you should be able to start lowering the low pass frequency until the midbass frequencies are reduced to the point you think it sounds good. You can also try the "24" setting to see if you like the steep rolloff better. I like it, but it is harder to blend it with your mids. The high pass will be used as a subsonic filter. It does not need to be set at 30 Hz. around 20 Hz will work great, unless you plan to play 20-25 Hz test tones all day at 2500 watts. . . I usually play material that I would normally use to demo what I consider "low" bass. You can watch the cone excursion and listen to the output to help determine the optimal SSF setting for you. Read the manual and try more settings. You should have an awesome setup there, don't give up yet!!! Good luck, Brian [/QUOTE]
