Question about Sony CDX-GT300 CD Player

1 Answer

Subwoofer in my car works only on tuner

I purchased a Sony CDX Gt-520 Head Unit for my car. I already had an amplifier from Interfire and 2 10'' JL Audio Subwoofers. I hooked up everything and it works extremely well with the tuner. However when I switch to the cd player or my auxilary (which has my ipod connected it) the amplifier shuts off and the subwoofers do not play. I have reset my head unit thinking it was a setting but it did not work. Do you have any ideas on what could be wrong?
The product underneath is not my product but you couldn't find mine.

I had the same problem. most radios have a power antenna wire and an amp turn on wire it sounds like your amps are being turned on by the power ant wire that loses power when you put a cd in try swapping the blue with blue and white wire this should solve it

Check the connections between the head unit and the XM tuner. If the connections are good check for power and ground.

MEX-BT5700U, no sound in speakers in CD source, tuner source OK.


What many people do on this model is connect the remotes wires improperly. Use the solid blue wire for the amp and the blue with white stripe for the connection to the car.

I have a Sony CDX-L550 head unit in my car but this morning when I started the car I turned the volume up nothing happened so I kept turning it up until suddenly it blared out and the whole unit shut down...


You may have damages a mosfet on the internal amplifier if all the fuses check out.
There will still be power to the unit, but the internal amplifier will not work.

How to hook up a head unit to an amplifier,when the head unit has no RCA plug ins? It was done before in my old car now i cant remember how.


Here is a link to owners manual for Sony CDX-GT300.
http://www.docs.sony.com/release/CDXGT300.pdf
Here is a link to installation instructions. It looks to me that there are front and rear line out RCA connectors on the back side of your head unit. (Unless, this is not the model of your head unit)
http://www.docs.sony.com/release/CDXGT300_Installation_Guide.pdf
There are devices that are capable of converting speaker level output to line level (RCA) output. I know Scoch is one brand, and here is a link to others.

It wont run my subwoofers


See if a) the head unit has a separate subwoofer output control, and make sure it's activated; b) the amplifier you're using for the subs has the gain control properly turned up; c) if neither of these fixes the problem, make sure all of your amp fuses are intact; d) make sure the subwoofers are in a properly-sized enclosure (too much or too little airspace can affect the sound output).

Rear speakers


If have a VOM check for voltage at the amp. If not, a cheap trouble light (often in cheap tool bin) will tell if have voltage. this will tell if the problem is the head unit or the amp or wiring.

Occasionally the remote wire will have a fuse in line.
