Possible to use sub without preamp?

I'm using a DAC with volume control directly into my power amp. Can a sub be hooked up in such a configuration or would I need a preamp? Thanks!

You would run them in parallel without any degradation. The REL will actually emulate the sound of your amp to make it seamless. You can use Monster solid brass 1 in 2 out splitter and as long as you use a left and right one to drive the sub in stereo, your output on your digital source should be able to drive that load with no issue. Both of these options are better sounding than most outboard crossovers.

If it is a powered sub it uses the connection for signal only and takes no power away from your speaker amp.
