My radio speakers dont sound right. All trebble until the inside of the vehicle warms up. Then thhey sound correct. Trplaced the radio thinking it was that, still the same.

The volume control on your radio is called a potentiometer, which may be going bad. It works better when its warm because materials expand as they warm up and make tighter contact with each other.

It is also a possible a bad wiring connection exists. Poor contact will cause static, poor audio quality and intermittent output.

Your radio will have plug type connector(s) Your speakers will most likely each have two wires with single female spade connectors of different widths (keeps the polarity correct) the wire with the stripe (of whatever color) will be connected to the negative (-) speaker terminal.

So you need to check all the connections, one is making poor contact.
If both speakers (assuming you have two) sound good or bad... then start with the plug connectors for the radio and any independent black ground wire coming out of the radio.

If one speakers sounds okay check the connections on the other one. You check the connections by carefully pulling the speaker wire off of the speaker and then carefully pushing it back on making sure it feels tight and secure.

PS: If you pull the fuse for the radio, the radio will have no power and will not work. The radio coming on proves the fuse is good.

PSS: Your owners manual should provide lots of information on your sound system components.

Hi Jamie, Here's an old trick which you may find useful. Take a run down flashlight cell and confirm the wiring to the speakers by holding the earthing line of the speaker cable to the negative and flash the positive side with the feed to the speaker one at a time. With each swipe you will hear a thump from each speaker as you connect and disconnect. In that way you can confirm the cables are the ones you are connecting. Color coding is not always the same. Use a voltage test meter to confirm the constant power and ignition power and don't forget to earth the set once all other connections have been made, Withour an earth it won't work, but you know that anyway. Regards John

you should let it recheck from a electrician, probably one of your wires loose or something burned on the first i could think

All you need to do is get the power, ground, and antenna hooked up then start with two colors matching, example: one purple and one black with purple line hook those up to a matching speaker wire then turn stereo on and go to balance setting choose back left if speaker does not sound then go back right and if speaker does not sound then try front speaker right and then left once you find correct speaker move on to next two matching remember to. Mark wires FL or fr or bl or back right. Good luck

I had the exact same issue with my 2007 Yaris. I took the radio out and checked all the connections- (all Good) then traced the wires through out untill I reached the trunk. I had a bunch of stuff in the trunk that had some how hit the speaker connections and bent the connections on one of the speakers. I removed all the stuff from the trunk and re-solder the connections. After that the speakers kicked back on for the entire car.
Check the trunk - if you have it loaded with junk like I did, this may be the cause of your speaker failure.
Good Luck!

I have the same problem. Seems when it is dry outside, the radio works pretty good but when the humidity is up, speakers dont work and sounds like treble in the other speakers.
I am to the point as to put a aftermaket radio in the truck.

run new wire to the speakers is what i would do but u have to do it to all due to there possibly being a pre amp in the vehicle.

You may have a factory amplifier in the rear of the explorer in the right cargo panel. You need to supply power to it by connecting the amp power on (Blue/White I think) in the dash to a power source (such as red on your stereo harness) so it comes on with the key. If you do have the amplifier, that's why you have no sound.

Try the following, this is an 1997 USA Integra

Radio Constant Wire 12V+: Blue/White
Radio Switched Wire 12V+: Yellow/Red
Radio Ground Wire: Black
Radio Illumination Wire: Red/Black
Radio Dimmer Wire: n/a
Radio Antenna Trigger Wire: n/a
Radio Antenna Location: Left Rear
Front Speakers Size and Location: 5 1/4′ Doors
Left Front Speaker Wire (+): Blue/Green
Left Front Speaker Wire (-): Gray/Black
Right Front Speaker Wire (+): Red/Green
Right Front Speaker Wire (-): Brown/Black
Front Speakers Size and Location: 6 1/2′ Side Panels
Left Rear Speaker Wire (+): Blue/Yellow
Left Rear Speaker Wire (-): Gray/White
Right Rear Speaker Wire (+): Red/Yellow
Right Rear Speaker Wire (-): Brown/White

if you think its a ground problem just run anotherground from the speaker to check.hope this helps
