I DONT HAVE POWER CABLE--SUBWOOFER TO RECEVER

If your Pioneer SW-8 subwoofer is not powering on, there are a few things you can try to troubleshoot the issue:

1. Check the power cord: Make sure that the power cord is securely plugged into both the subwoofer and a working electrical outlet. If the power cord is loose, try unplugging it and plugging it back in.
2. Check the power switch: Make sure that the power switch on the back of the subwoofer is turned on.
3. Check the circuit breaker: The subwoofer may have a circuit breaker that has tripped. Check the circuit breaker on the back of the subwoofer to see if it has tripped. If it has, reset it by pushing the button back in.
4. Check the fuse: The subwoofer may have a blown fuse. Check the fuse on the back of the subwoofer to see if it has blown. If it has, replace it with a fuse of the same rating.
5. Check the auto power function: The subwoofer may have an auto power function that turns it off after a certain amount of time if there is no audio signal. Make sure that the audio source is playing and sending a signal to the subwoofer.

If none of these steps resolve the issue, there may be a problem with the amplifier or power supply in the subwoofer.

try connecting ur power wire to ur remote one worked me for

If yourt subwoofer has a Standby setting, turn it OFF. Have the sub stay on whenever it has power.

That would depend a lot on the subwoofer, which you did not name. I'll assume it's a self-powered model of some sort.

A sngle RCA cable from the Subwoofer Preout wll get you started. The other end is unknown.

You'll aslo have to set up the recever to know it has a subwoofer and other parameters. Find the manual at retrevo.com.

You don't identify the subwoofer so we have to guess.

Since it only supports a powered subwoofer I would guess you just need a standard single RCA cable available anywhere hifi cables are sold.

Try to check speaker fuse (could be low impedance resistor) inside the unit. But the most possibility is the Power Transistors are defected.

I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!

Hey,

I just got one of these units, the SONY SS-WG990.
The RCA cable is direct conection to the speaker.
It requires external AMP.
The other cable is just for the system switch and LED.
If you just have this unit, all you need is an AMP to
feed it.

Might not be eathed properly. Check the earth on the battery as well. Theres more juice goin through there now so it might need a bigger earth or ground.
