I just installed some new kenwood 6 1/2'' speakers in my tacoma today and have a problem. For some reason my passenger side speaker has a slight distortion sound when the volume or bass is up at higher levels. I did balance left and right and the left speaker is fine at the same level, but the right one sort of makes a squeking/squeeling noise. Its not horribly loud, but enough for my ear to notice it and bug me. I dont know a whole lot about stereo systems so some advice would be very appreciated.

 

Maybe you have your wires crossed.

 

im positive they are correct. i thought that was possible too so i swapped em, and no change. when others of you install new speakers do you replace the factory wiring. the customer service from the car audio place said that factory wiring is usually garbage. i have never replaced mine on previous installs. but figured on a tacoma with only two speakers it wouldnt be to hard if needed

 

I just finished dropping new Kenwoods in the stock holes in my 95 4Runner and had a similar issue with the right-rear speaker ... annoying little buzz/crackle and whine/whistle sound. Turned out to be a loose ground behind the dash. Also, if you don't run your own wire, at least run the head unit ground direct to a good ground, not to the flimsy Toyota wiring.

my next guess would be the ground wire too.
