Hi Mate,

Thanks for the response,

Some questions if I may:

Fronts and subs are setup differently. ie my fronts are 1 way NOT 2 way. So I setup subs as 30hz subsonic filter 12db slope.

How do you set gains on speakers ? I thought you set gains on amps ?
Why set the sub channel to 20% of the 100w RMS ? The Eartquakes are rated at 300w max so surely they can take 100w RMS ?
If the L7's are rated at 75w RMS why set the amp at 20% for that channel ?

I am confused by your kind response mate. I think you are reffering to setting up the front channel as 2 way ? I could be (and probably am) wrong.
