Ihave an sx-316 multi channel receiver cut surround right speaker wire to add more length no sound at all put original speaker wire back together still no sound

Make sure the wires DIDN'T get crossed

Look likes a connector is ground loose or only a cable is crushed

if no other parts are connected a capacitor problem somewhere

check the attached service manual.
H appears normal and L appears to be defect.
also see page 88 to troubleshoot further Pioneer SX 316 Service Manual

Hi Ray,
Here is a very simple link for connecting speakers to your receiver:

Pioneer SX 316 Operating Instructions Manual Connecting The Speakers

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!

Mine is having this problem now.

Tried re-inserting the speaker wires.
Tried resetting before it shuts off.
Tried disassembling but solder joins are still nice.

It still shuts off soon after power up. Time to spend money? :(

Surround Sound System Settings ---- Correct Time Delay Setting in Multi-channel Audio

A correctly set surround sound system can yield dramatic improvements to your
home theater sound or multi-channel music listening experience. In particular,
a correctly set time delay setting between the different channels is essential
for a realistic and unified surround soundfield.
Luckily, most of today's surround processors make setting the time delays
between the rear and the fronts a matter of a few entries in the setup menu.
Yet having a proper understanding of the principles behind correct time delay
settings is essential for the best results.
In this guide, we explain the principles behind time delay settings in surround
sound and show you how to adjust your surround processor or AV receiver for the
best surround sound field.

Time Delay Setting in Multi-channel Surround Sound Systems

Correct home theater speaker placement and properly balanced sound levels
between the different channels in multi-channel audio, while crucial, are not
enough to sustain a unified soundfield in a surround sound setup. A correctly
set surround sound system requires that sound from all the different speakers
reach the listener at exactly the same instant.
This explains why all fronts, left, right and center channel speakers, should
be set at exactly the same distance from the listening position. At the same
time, in a typical home theater setup, the surround speakers are closer to the
viewer than the fronts.

To compensate for this distance discrepancy, surround sound playback systems
apply a split-second delay to the surround sound channels.

DVD audio straight in from its highest quality audio output. Use the stereo audio output to run straight to the TV for casual watching through TV speakers without the Pioneer involved.

A TV is just a glorified night-light, not a sound source - get its related audio from the Cable Box, ditto the highest quality

If you receiver doesn't have phono inputs,you will need to buy an inline phono amplifier.Phono inputs have a built in amplifier,all others don't.Try Crutchfield.com.If they don't carry them,they will tell you who does.

try turnind down the sub from the amp itself it might be putting out more volts than the subs input can handle check your standing wave feature to make sure the trim is not up too high
