How do you hook up two subs to my yamaha v 661 reciever?

Question

Do they have to be the same sub because when i hook both my klipsch 12 and my mtx 12 only the klipsch works. My mtx works in my basement by itself though.

Answer 1

Use a "Y adapter" (RCA male to two RCA females). Plug the male into the LFE output on the receiver. Both should work, although you will need to balance the output levels of two subs. If using the crossover on the receiver turn off the crossover on the two subs.
