How to Connect 2 Subwoofers to One Receiver

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.

Things You'll Need:

Home theater receiver
Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores.
2 RCA subwoofer cables
2 subwoofers


Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.

Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..

Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.

Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.

Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.

Tips & Warnings

Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.

Disconnect the subwoofers from the power supply while making the audio connections.

Have a nice day...

I recently moved and am having trouble getting my phillips subwoofer system model : MMS171W hooked up properly There is a loud background hum when I attach it like I think it should be attached. Any ideas...

This is most likely a "ground loop" and is caused by using two different electrical outlets for the two parts of the system -- main receiver and subwoofer amp.

Try using the same electrical circuit (wall outlet) for all of the equipment in the home theater, using a power strip or strips as needed.

Power issues: will not turn off or function

Unplug all of the speakers and power on.Its possible that one of the speakers is causing the protection circuit to activate.If powered on and subwoofer works start reconnecting one speaker at a time( after powered off) and retest each time.One Speaker may be bad.Its also possible the output ic is failing under a speaker load.There are no fuses related to this issue.If its not a speaker problem then the subwoofer will need to be serviced.

Please update your post with any Model Numbers that you can retrieve, especially the subwoofer. Off hand, and with the limited amount of information that you have provided, I would GUESS that your subwoofer is simply overheating, and is being shutdown internally, hence protecting the fuse because no short is detected. If you haven't moved and or vaccuumed/cleaned around or near your system regularly, dust, pollution, name it, builds up and can easily prevent electronics from breeathing/venting properly.

Sounds like your original and this sub have bad amps. The amp for the sub is not the same as the amp for the other speakers. The old unit has a dead amp and this new one is on the way out. (Pulling too much current on high bass)

SUBWOOFER WON'T POWER ON (Grounding out???)

Check your cable that runs between the main unit and sub for bent pins. If they look fine there may be a short in the sub itself that is causing it to go in to shutdown.
