Hello
I recently buy an NAD Processor T163.
This Processor has an adjustable crossover of 40-200Hz.
I have a box of 60 litres with a 12’ drive of Monacor (SPH-315). Do I need to make a crossover to put in my DIY subwoofer?
If not, can I use my NAD C320 as a Power amp to connect directly to the sub (drive)?
As I have two pre-out in the T163 can I connect this two to the Main In of the C320 and “Bi-amp” the sub?

Thanks,
Cristiano
 
If you have a crossover in your preamp/receiver, there's no reason to put one in the subwoofer.

Yes, you would connect from the "sub out" to any mono amp or one channel of a two channel amp... and then to the sub.

You can use two outputs feeding two amplifiers ONLY if the sub is a dual-coil driver. You CANNOT connect the outputs of two amplifiers to the same woofer coil. As an alternative, if you have a way of inverting one of the inputs (simple opamp circuit will do this), you can bridge the two channels of the amp to drive one coil.
