Clarion DXZ935 Tuning

I just got the Clarion DXZ935 HU from a friend for free.  After installing the unit in my Civic, I read the manual.  However, it wasn't very descriptive about some of the features.  If anyone could help me with the following issues, I'd greatly appreciate it.

1) AC-PII PRO

     a) Time Align - What length is it referring to?     b) SP-Gain - Should the amp gain be set to the minimum and this gain only used?2) AC-PII STD     a) Diffuse - What is the number based on (1-10)?     b) Car Width - What is the number based on (1-10)?     c) Car Length - What is the number based on (1-10)?3) P.EQ     a) Band - What band is this referring to and what do the numbers (1-3) represent?     b) Freq - What frequency is ths referring to?     c) Gain - What gain is this now?  How does this affect the gain when in AC-PII PRO mode?     d) Q - What is this and what do the numbers represent (1-20)?I asked my friend about these features but he has no idea since everything was setup for him when he got the HU installed.

Also, I have a RF 360.2 that runs my ED 10A2.2.  I was wondering about the adjustment for the gain on the amp.  After installing this HU, the sub is almost silent.  There are 2 dials but no markings on the dials.

Any help would be extremely appreciated.

I have the 945. Real nice. Lots of similarities. Get the manual here http://www.teamclarion.com/sharedwebdbs/clarionsupport.nsf/b519d112bdcca8b588256a630071fab1/5a45895dfaa4e82488256cc50062d72a/$FILE/DXZ935_Eng.pdf 1.a. length? - Not sure 1.b. SP-Gain? - On the head unit, set the gains to the middle, then set the gains on your amp properly via a sine wave and a meter. Then you have some room to adjust the gains via the h/u up or down as needed. 2.a-c difuse? - not sure what the numbers are based on. I think they are abitrary. 10 being a bus and 1 being a metro?? 3.a Band - you have 3 adjustment bands. For example band 1@60hz, 2@250hz & 3@1khz 3.b. Freq - The frequency is refering to the frequency you would like to adjust. 3.c Gain - How much up or down you would like to adjust the specified frequency 3.d Q - is the sharpness of the curve. A 1 is fat and a 20 is sharp
