I want to use two subs at one time.
Only one sub out on reciever.
Is there a way to do this that will work?

Radio Shack sells a "y" adapter (or splitter) with the proper plugs on each end. One "male" that plugs into your receiver, and two "females" - one for each of the subs.

Here is what you are looking for: Adapter

xmgb:

Check the back of your subs. Axiom has line-level outputs on the back of its subs that let you run a coaxial cable to daisy-chain a second subwoofer--or a third. Other manufacturers may or may not offer that output jack.
