The right side of my speakers work fine but the entire left and middle dash speaker doesnt work

it will be the amp has gone on this side there is a chip on the main amp that controls sound out this is also used by the main board to control left and right speaker control when this goes you will have either one side working or dead both sides.

Determining the Cause of the Problem Let's assume our system has a head unit, a crossover, a two channel amplifier and two door speakers with only the right speaker working (the left speaker is not working). If the door speakers are behind the door panels then we want to make sure the speaker is the problem before removing the panel. We'll work backwards starting with the amplifier and ending at the head unit. Testing for a Speaker Problem With the vehicle and the stereo turned off disconnect the speaker wires for both the left and right speakers at the amplifier. Now connect the left speaker to the right amplifier output (which we know works). Turn on the stereo system and make sure the balance is set to the middle position.If the speaker still doesn't work then the problem is somewhere between the amplifier and the speaker Testing for an Amplifier Problem Now we'll need to see if the amplifier channel is bad. Put the left speaker back on the left amplifier channel and the right speaker on the right amplifier channel. This returns the speaker wiring to its original configuration. Again, with the vehicle and stereo off unplug the RCA cables from the amplifier's input and switch them so the left cable is in the right input and vice versa. Turn on the stereo system. Testing for an RCA Cable Problem For any intermediate components between the amplifier and the head unit follow these steps for each one. We only have a crossover so we'll just do this once. Begin by testing the RCA cables between the intermediate component and the amplifier. Unplug both RCA cables from the intermediate component's output. Now plug the working channel's RCA cable into the non-working side of the crossover. In our case the working channel is the right so plug the right RCA cable from the amplifier into the left side of the crossover. Turn on the stereo system.
If the right channel continues to work then you know the problem is in the RCA cables between the amp and the crossover. esting for a Crossover or Equalizer Problem At the input of the intermediate component (in our case the crossover) flip the RCA cables around (left to right input and vice versa). Turn on the stereo system.
If the right channel continues to work and the left channel continues to not work then you know the problem is in the intermediate component. Replace or repair this component.
If the problem is now in the right speaker and the left speaker works then the problem lies before the crossover. Turn off the stereo system and return the RCA cables to their normal places.
Testing for a Head Unit or RCA Cable Problem Pull out the head unit from the dash so you can access the RCA cables. Unplug both RCA cables from the head unit. Do not disconnect any other wiring. Plug the right RCA cable into the left channel of the head unit. Turn on the stereo system.

Check the fuses. The left and right sides have seperate fuses for the lights. Not sure about the speaker, that might just be a coincidence that it doesnt work. I reacently worked on a hyundai that had the same problem.

maybe the speaker is going bad but first try to replace extra speaker try to connect if still the same your car stereo is bad on the right ic output

Have you checked the balance foe left to right if it's full right no music will play through the speekers but you will still get the beep and other sounds like that that should be where you chand bass and treble settings along with fade center it and you should be good

first> road vibrations can cause cable connections to come loose so you can start by taking out your radio and making sure all of the questions in the back are connected as they should be.
Second> if this doesnt seem to work then the next step is to check the wires going to the speakers that arnt working (this will b quite a job, but if you can do it, it will save u quite a bit of money) .. checking the wires your checking for >bad connection to the speakers >cuts in the wire or if any part of the wire is touchin any other metal object

make sure the speaker wires in the car do not have one side grounded.the output on the clarion is a floating output and cannot be grounded.the best solution is to look at the wiring on each of the speakers,and match them out to the ones on the clarion.the most common colr code is white front left,gray front right green rear left and purple rear right.each speaker has a plus and minus.mixing them up will result in the speakers being out of phase and result in poor bass performance.i would wire the wires directly to the clarion using crimp connectors.the first thing i would do is power up the stereo out of the car to 12 volts,and using a speaker make sure you have sound coming out.the yellow wire which is the clock/memory is a must to be connected to constant 12 volts or no sound can result

try pressing the right button of your stereo 3x which i think is for the balance of the speakers probably it is only balanced on the left side just put it in the middle

hot cold selector switch bad sound like it needs replaced

Ihave never seen just a middle speaker in the dash but I have seen left and right dash speakers there is a panel that goes across the dash by the windshield. it pops out with a screw driver you may have to remove the trimfrom the a post first the speakers are there
