Re: fuzzy & crackly
Its the problem with the ac adapter which you are using might be your adapter is not working properly the adapter consists of step down transformer which is not very much durable some times so change the adapter and see if u dont have any adapter to connect just the direct wire to the supply then the adapter will be inside of woofer or the speakers change that adapter check this it works

I think I have experienced this problem before with my Sony stereo set. It could be a sign that your receiver's amplifier is giving out. Best that you can do is bring it over to an audio repair shop for a checkup. If my suspicion is right, you're gonna have to replace it with a new one. Don't worry, amplifier chips are not that expensive.
And lastly, when any part or component is replaced, be sure to ask the technician to give it to you. You can keep it for your reference.
mine did the same thing today , i just bought these new 2 weeks ago . the black prong speaker works in both ports ..
the yellow prong speaker is the one with the malfunction .
it works sometimes but when i turn up the volume louder it dies out .
You would need to rewind the coils.Do not try to do it by yourself if you have no idea what you are up-to...this time it was transformer next time it could it could be your circuit.Take it to a professional,the charges won't be much. Good Luck.
Check to be sure there are no speaker wires touching ground, and that the wires are connected in phase to the head unit.

The symptoms you are relaying definately sound like an internal amplifier problem. It is fading in and out for a reason - usually due to heat.
Have you had the radio bench tested (seperate from the car) to eliminate the car as being the culprit?
Since the radio was run with damaged speakers originally, the output or amplifier power supply on the amplifier may be bad.
As an alternative to repairing, I would suggest investing in a small 2 channel amplifier to power the speakers.
The radios claim 50W per channel, but in reality give 12-15W RMS power.
A dedicated amplifier with built in crossovers and gain adjustments will prolong the life of your speakers and add to the tonal qualities of your new speakers. Instead of turning up the volume on the head Unit, and sending out a distorted signal that will blow your speakers, an amplifier will give more CLEAN power to them, so it will be louder at a lower volume setting.
This will bypass the internal amplifier on the radio, and send a Low Level signal ONLY thru a set of RCA cables.
hi. i have a sony amplifier. i plug the speakers in like normal. i turn it on and the right side speeker works fine. but you half to crank it up all the way just to barely hear the left speeker. we switched speakers and its still the same effect. we think its the amp itself. we tried our balance settings. it was fine. but right now its just playing one speaker louder then the left one. can anyone help me?
