What do i need to install a subwoofer

Check pos and neg wires on speakers and radio they may be crossed.Does the radio have bass to it or sound like tweeter

Sony's web site will provide a free owner's manual download, but you'll have to find out the model number. It should be printed on the faceplate, and will probably start with "CDX". Sony has used "Xplod" for their car audio line for at least the last 10 years, and 52x4 is a pretty common power rating for them, too; so you'll need more specific information before you start searching.

Once you find your model number, here's the link: http://esupport.sony.com/US/perl/select-system.pl?DIRECTOR=DOCS

For the stereo the following will work.

If the receiver has inputs you can use a male rca's to a 1/8 stereo jack. It should fit the ipod on the headphone side and you can use it through the stereo.

is sounds like the antenna cable is not plugged into the head unit. Pull it out and check.

it should have turned on what car its in and did u use a kit let me know

Hello everroth,

You can download a copy of the manual from Sony here. It's only a 2 page PDF document and figure 3 shows the wiring color codes and wiring diagram.

Hope this helps.

There are many CDX models, but try this site:
