What does the SW refer to or connect on the back of the JVC receiver

I don't see any references to a KD-6320 receive. Please check the model number. JVC has a KD-G320 AM/FM CD receiver. The installation and instruction manuals are available from the product support page here: http://support.jvc.com/consumer/product.jsp?modelId=MODL027623 . The direct link to instruction manual is http://resources.jvc.com/Resources/00/00/93/GET0349-001A.pdf . You can also check here: http://books.jvc.com/ for JVC manuals.

I hope this helps.

The connector on the SW board may be broken. If you are technical, replace the sw board LVA10932-12A

The radio's Red wire is not getting 12V from the ignition sw. If you have a tester, check 12V on the wire when the car key is turned to ACC or ON

SW means sub woofer, not necessary means center speaker in all receivers. Instead of setting 5ch stereo, if you have 3 speakers. try to set "3channel" or "simulated". If you own more than 3 speakers, you may refer to the user´s manual to correctly wire them to get the full sound.

if there is not a sub or SW rca connection on the back then there is no setting for it

on the back of your receiver is a subwoofer pre-out, connect one cable here, and connect the other end of this cable to your subwoofer - line level in. (depends on your subwoofer and receiver) but that's how mine is connected. yours will be similar.

Check wiring. Yellow to Battery, Red to ignition sw, black to ground. Confirm the functions. If everything is OK, then connect speakers, antenna, etc.

Do not cut the wires from the car. Instead, call Crutchfield at 888-955-6000 and order the adapter part number 120701003. When you call them, ask for color coding. For JVC, refer to the attached picture. Match the adapter color code with that of JVC. If the adapter color code is the same, then connect ground (black), battery (yellow), and wire from ignition switch (red) securely. Turn on the car and see the radio works. If it works, connect one by one speakers and confirm. Remember, perfect connection gives reliable installation.

Hello pmdharan, It sounds like the subwoofer is not turned ON. Go to MENU ITEM > SPEAKER SIZE >SW (subwoofer) and select ON. Hope this helps.

Usually, a subwoofer will have its own built-in power amplifier. Thus, it will be designed to plug into a standard RCA jack (the type used for DVD players, etc). rather than having wires to connect to a speaker terminal block. Look for a jack on the back of the receiver called "Subwoofer", or simply "SW". If your subwoofer has 2 single wires, it WON'T work with your reveiver's subwoofer output, as this output only carries a line-level signal and is not amplified. You would need a separate power amplifier for this type of SW. If your SW speaker has a DVD-type plug, it should work fine with the receiver's SW output jack.
