Power input lead for kenwood ksc-wa82rc wiring diagram

Take a look at this manual diagram. https://www.manualslib.com/manual/359815/Kenwood-Ksc-Sw10.html?page=5#manual

Given the above is not your model, at least it shows the 10 pin. Ironically, below I offer a diagram of your model. The irony comes in the fact that the diagram appears labeled in Japanese But if you compare the two diagrams, maybe something will make sense from the one with the English labels. Otherwise, you might fire off a query to Kenwood customer support. https://www.manualscenter.com/manuals/kenwood/kscsw900-owner-manual.html

I don't have any information on how to power supply a kCSWA900 Kenwood subwoofer. However, I can tell you that the Kenwood KSC-SW10 compact powered subwoofer has a built-in amplifier with a 38 watts RMS power and a wired remote for control over volume level, variable low-pass crossover (50-120 Hz), and selectable phase control (0°, 180°) . The subwoofer comes with a power/ground wiring harness and preamp (RCA) and speaker-level inputs .

You may need to wait a few minutes for the "Get Manual" link to appear below the preview picture.

I used a computer power cable (the one that plugs into your IDE HDD) and soldered the male end onto the circuit board. Sorted :)

It tells you on the top of the deck or lables on wires. the front speakers are white= + and white with a black line= - and grey+
grey with blak line= -.rear are green and purple

It looks like the S-video you need one end to be male and the other is female end.The high quality the S-video wire the better the sound.Make sure you get a long enough cord. Take it with you to radio shack or and car audio or home audio find the female end of the S-Video and it should plug in perfect.Wire it up and enjoy some tunes
