thank you

I think you're missing the manual(s).

http://www.retrevo.com/support/Kenwood-VR-357-Receivers-manual/id/480dj197/t/2/
describes how to use a >> powered << subwoofer with the VR-357.

Speakers are OUTPUT devices. As far as the manual goes there is no STOCK subwoofer with this receiver. What's yours and does it have a manual which might answer your question?

Did you get a manual with it? According to the Sony site this speaker originates in Sony MHC-GX450.

"This product bundle includes the following models:
HCD-GX450 - STEREO MINI SYSTEM
RM-SC3 - REMOTE CONTROL for Shelf Mini Systems
SSRG444 - FRONT SPEAKER FOR MHCGX450
SS-WG450 - SUBWOOFER FOR MHCGX450"


Find the manual here and learn a bit about your seprated sub...

See page 7.

As can be seen, the subwoofer has two connections to the mothership, very unlike the standard speaker level (+/-) speaker wire or RCA-Line-Level subwoofer out that 'normal passive or active subwoofers use, respectively.

Not knowing which of those your unspecified Pioneer receiver supports, it is impossible to say. Does your Pioneer have that control jack?

Mini-systems are generally not designed to be pieced out and used with grown-up gear. The absence of standardized connections is the clue.

Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Instructions


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.


Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.


Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.


Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.



If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

This manual discusses it somewhat.

Basically, feed the self-powered (active) subwoofer from the Subwoofer Out. There does not seem to be a way to adjust the subwoofer output to match the rest of the speakers because the sub out is muted during the adjustment procedure.

Another way would be to refer to page 15. The note at the bottom right suggests your subwoofer might accept full range speaker level inputs. Refer to the manual for your sub. I believe they mis-printed it and meant "active" subwoofer, as simply wiring a passive (unpowered) sub across the front speaker outputs might cause some amplifier overload issues and you would have no way of balancing it anyway.

If this is a house unit, it'll take 110V AC to power it up, then there is a voltage regulator after that that drops the voltage, so the electronics don't burnout.

Hi,
The manual can be found on Nikon's website or click on the following link: http://www.nikonusa.com/pdf/manuals/lenses/AF/AFSVR70-200_2.8G_(80)05.pdf
The manual is a combination of several languages all bundled together. The English portion is from P14 - P21.
Hope this helps.

The output of the Sony is "signal only" not power. Being "passive" like your sub. What you need is a sub amp, and they are not cheap, 400-600 on average "min". Unless you have a Velodyne 15 or 18, just get an amplified sub, they start around 150 new. Hope this helps
