Would this wiring be right?

The amp is a hifonics 1500 BX.

The Subs are Alpine Type R's (Model 1221D) at 2 Ohms and DVC

The real question I have is if you can connect two wires to one terminal like I did on that 1st terminal.
If there is a better way to install this then plz do tell. One thing to keep in mind is that the two subs are totally separated in the box and have there own chambers.
