So the way its set up now is... I have rca jacks going from Pre out Front speakers from Elite amp to low level in on Sub. From low level out of sub to variable in on Nad power amp. Then I have my 2 front speakers coming from the Nad to the speakers.

I do have Sub power. Its on in all mods. My sub has a volume switch and a 50 below all the way to 120 above. I have volume set at half and the number buttom set at 80.

Is there a speaker adjustment for cut off in my amp??? Ie... set it at 80 crossover ect????
