I recently bought 2 audiobann sound q subs, they are in a custom box. I have hooked them up to my system i had and they are not working. There is only one port for the speaker wires, but two subs. Is this normal? i have never seen it before. if its not what can i do to fix it and get it working?

What were you pushing these speakers with? how many Ohms?
