MY PIONEER WOOFERS DOESNT WORK - Pioneer TS-W252R Car Subwoofer

Hello,

I don't recall correctly if your Pioneer has a sub out RCA connector, and if the Kenwood SW-07 has a low level input. So the usual way is to connect it using the speaker wires.
You connect either the FL or the FR to the sub and it should work.

Good luck

The only thing you do is to open your receivers,then locate the output connector if you see the female RCA jack ,then push it out the broken piece ,that's it

If you are running three 8 ohm speakers in parallel then the total impedance would be 2.667. If running two 8 ohm and one 6 ohm speaker in parallel you would have 2.4 ohms. This will burn out your amp pretty quick. And very possible won't play at all. Though I have never attempted to play a home amp down that low in ohms. Guessing you may have an older model Denon type amp.

any will work go to best buy

Hissing? How loud? A sub isn't even capable of making high frequency sounds at normal volumes.

The Pioneer manual would tell you how to enable and test the subwoofer output.
Page 17 and the MACCV procedures on Page 33 (auto) or 43 (manual)

I have the same problem, your sub-woofer is passive and you need a powered sub-Wfr, more money is the only FIX!

My experience with them is that they would work as they don't change much from model to model year. You may call the customer support and they will most likely help you
try CS @ 800-421-1404 or try the parts hotline to investigate

you have a bad cable

Hello,
The subwoofer is totally independent from your Pioneer VSX-D412. You can check if it works like you did with a finger on the hot point of the RCA cable (not very good test, as you will hear noise and can't say if that means it works OK) or better connect a known receiver to the speaker connections in the sub and test to see if it’s working properly.
Regarding the receiver, you may not have enabled the VSX to output to the sub. Read the manual on how to check for that. Only Dolby Digital 5.1 signals will allow the sub out, in a receiver of this level. It normally will not let you use the sub in stereo mode. Some more complex units will allow you that, but I believe not this model.
Good luck

I got the same issue. But, I go ahead hooked it up two banana plugs on teh VCR outlet. It works fine on my Cerwin Vega Sub.
