Q: How is the input signal excepted by this subwoofer?

This thing is amazing. Really easy to install besides digging the giant hole to put it in. I’m pushing it with a QSC CMX800Va In bridge mode. Also have 10 garden speakers in the system and no hiccups. The sub sounds amazing and carries very well throughout the garden it’s in.
