Subwoofer Good Day,  I have no subwoofer output from my unit. I have checked all connections and speaker settings carefully. However, when I separate the receiver from the unit hook up a dvd player and two speakers, the subwoofer plays fine. The impedance selector is set all the way over and set properly (all my speakers are in working order, as is the other componants). Am I missing something?  Thanks Larry

If you are replacing the existing door/deck speakers with replacements of the same size and not adding an amplifier, you will be able to use the existing wiring, making note of the positive and negative notation.
Subwoofers, on the other hand, require an amp. There are subs that have an integrated amp in the enclosure, otherwise you will need to buy a separate amp. Connecting the amp to your existing system will highly depend on what outputs your head unit (aka stereo) has. If it has pre-amp outputs, those can be run straight to sub amp. If there are not pre-amp outputs, you may have to buy a "high level" adapter that connects to the same head unit outputs as your speakers.

Well its a single channel prolly 400watt 2ohm check and see if the speaker has two separate sets of wire on each side of the speaker if so bridge it and connect it to that channel then you should be Good to go

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!

Simple things first:

Is it powered on? (sorry, I know that's too elementary)
Is it connected properly? (you have a cable securely plugged into your receiver's subwoofer line level output and securely plugged into the subwoofer in in the subwoofer)
Is your system configured properly to send a signal to your subwoofer?

• Does your receiver have a menu system you can use to manually configure your speakers?
• If it does, have you told your system that you have a subwoofer?
  
• If it does, have you set your other speakers to "small" (believe it or not, even with full-sized floor standing speakers this is a good practice)? Sometimes, if the other speakers are set to Large, an AV receiver may not output a subwoofer signal.
• Check all the rest of your receiver's speaker parameters through its menu system.
• On your subwoofer, do you have the Level turned all the way off?
• Where is the cut-off frequency set? (if it's set too low, and your source material doesn't go down that low, you may not hear anything through it)

Is the cable good? (use a multimeter to check)
Is the receiver outputting a signal through the subwoofer out port? (again, use a multimeter to check)

That's all I can come up with for now. Good luck.

If you meant that the subwoofer amplifier has the power in then we need to check the amplifier.If your subwoofer speaker is ok after testing with an 1.5 volt cell then you concentrate if the amplifer has packed up., After testing for fuse, speaker connection, speaker wires. you will have to check if your power amplifier output has failed. Since you have not mentioned the make/model i am not able to pin point but you may open and test for damaged output transistors, components and replace accordingly only if you are competant. Hope I could help. Good day

Have a good look at your set up in regards to volume output to each channels .
you may have only one channel working due to volume turn down or a faulty connection from the console head unit .
After going through all these , i would suggest to get your sub amp checked as you may have a faulty amp .

Hello johnwisam,

When using component speakers, it is normal to connect the head unit or amp outputs directly to the woofers and use a "high-pass" filter to the tweeters. Most component speakers sold as a set will include the correct filter along with wiring diagrams. The12volt.com web site shows examples of passive crossovers here.

Amps usually include built-in filters and a means of setting crossover frequencies according to the speakers attached. If the amp is connected to full-range speakers, it is set to "Full" or "BP". When used to drive subwoofer(s) only, the setting is most often "low-pass".

Most stock radios and aftermarket head units are relatively low power and just do not produce enough power output to drive subwoofers adequately. It takes more watts to move the larger cones and that usually means a separate amplifier.

Hope this helps.

The problem is that you need the satallite speakers , they have the volume control on them which thats why you only hear the subwoofer.. yes , i tried other speakers to it and no sound either.So you will need the satellite speakers it come with.. good luck!!

hi, ya , some recievers have its setup where u have to enable the sub out,, check the menu carefully, also the player menu if the sub is on or off, let me know..
