How do I hook up a powered subwoofer to a pioneer sx-316?


Many subwoofers accept both line level (RCA jacks) and amplified inputs (+ and - speaker terminals). The Pioneer SX-316 does not offer line level output, only amplified outputs via the PURPLE + and - speaker terminals. This means that in order to use any subwoofer with an SX-316, the sub woofer will need to accept a + and - speaker wire connections for input Your manual speaker connections are on page 11 of the manual which can be found here: http://www.manualslib.com/manual/260358/Pioneer-Sx-316-S.html#manual

Starting at the rear of the SX-316; run a speaker wire from the PURPLE + and - terminal (SUBWOOFER) to the + and - speaker input terminals on the subwoofer. See your subwoofer manual or experiment (at your own risk) with connecting the speaker wire from the SX-316 to the subwoofer's + and - LEFT only, RIGHT only or BOTH left and right speaker inputs. Do not connect wires from the SX-316 to the speaker OUTPUT terminals of your subwoofer.

Finally, adjust any variable low pass filter knob or setting on the subwoofer to the lowest frequency that your main speakers are capable of producing. If you're not sure what that value is, try setting the subwoofer to 100Hz and judge how it blends with the main speakers. If it seems a little too bass heavy and thick then reduce the setting to 80Hz. On the other hand, if the sound seems to be slightly thin and lacking weight, try increasing the setting to 120Hz. By careful listening and a bit of patience you will be able to get the sound to seem balanced and well blended.

Good luck!

My PSW350 has no sound


• Check AC plug and green LED onthe back; make sure outlet

is operational

• Check volume control on subwoofer

• For speaker level wire conections, check (+) on amplifier to (+) on

subwoofer and do the same for (-) to (-)

• Check that RCA line level inputs of the subwoofer are not wired from

speaker level outputs of amplifier


if problem still persist , the Sub may needs further troubleshooting

Hook up lower level input to the audio source 230 subwoofer but can't get any sound for the speaker that is hook up through the speaker level input or output.


The speaker level connectors on the sub are for use when you DON'T have an AV receiver-style subwoofer output. They only pass-through from YOUR amp to other speakers. You should NOT use both Line level and Speaker Level input to the sub.

What is your electronics? Have you looked at the manuals?

Apart from the "line input"


input and output are for low level ( as with RCA cable connectors) ,, the speaker connections are for high input, (red and black connections. ) you can run the mains to the (rca) from your receiver to run the sub woofers, and from that use the speaker wire connections, to go to the left right speakers, (out only not in) this is done if you want to run the subs and the Rt/lt/ speakers , eliminating the speaker connections coming from the receiver. which you could use for 2 additional speakers if you want

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...


I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

How do u hook up the infinity entra sub it has speaker level(input and output) that look like these red and black spots r for spearker wires and then line level input so I connect my music to the rca plugs...


Maybe if you described the setup with exact model numbers for everything involved we might be able to answer with specifics.

You could poke around her for the Entra Manual for YOUR model.

What they do NOT explicitly tell you is that the amp in the sub is not for your other speakers running off it's Speaker Level outputs. They're just there as a pass-through if you use Speaker Level from your own amp.

Line Level (RCA) IN to the sub will NOT pass anything out those Speaker level outputs.

Which is the best way to hook up a Subwoofer?


Last two questions first - YES, use an RCA splitter to share sub line level out between two subs and use one at the subwoofer end to share that line with both inputs on the sub.

Either attachment scheme you describe would work.

Not being a big fan of conversion/deconversion for no real purpose, I would avoid stepping the high-level input down to line level for use by the sub's internal amp, run RCA to the sub(s) and keep them physically and electrically independent of anything else unless cable routing is facilitated somehow by daisy-chaining other speakers from the sub(s).

Connect powered subwoofer


  • If your receiver has a dedicated subwoofer line level output, we recommend connecting your subwoofer to this jack. Most receivers will have just one (mono) subwoofer output, while quite a few subs require two inputs. You can use an RCA "Y" adapter cord , which is a cable with one female RCA jack at one end, and two male RCA plugs at the other. Some receivers require menu settings (such as "sub-on" or "front speakers-small") that must be made before the sub output will be active.

    Very low ouput from subwoofer preout


    The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.
