whats wrong?

A while ago, I was listening to music in my car. With the volume not even being half way cranked, my speakers go silent but my left rear one hissed. When I tried to use the balance function on my HU, the hiss wouldn't stop, even if I put the balance on my right speakers. I thought it might have been my fuses. Turns out, all my fuses are fine. Then I thought it might have been the amp. I brought the amp into school and had my electronics instructor take a look at it. He didn't have any test equipment that could test this amp, so he measured the transistors/resistors and all the componants. He told me everything was fine, nothing was blown, so I took his word for it. He said it might have been my speakers, so I just came back from measuring they impedence. Everything is fine there too, but when I go and plug in the second probe of the meter it makes a clicking noise, but I think this is normal because all 4 of them make it? What do you guys think is wrong? Can it be that my amp went into protect before the amp fuse? I didnt get a chance to look at the protect LED because I unplugged the amp before I noticed it.

so is it you comp speakers or subs? did you check for a loose ground. the rca wires etc. Make sure your ground is in a good spot and take the paint off the chas were you put it so its got the best. That is a small thing alot of people over look that causes some problems. Is it a motor noise like when you rev your engine it gets louder? Theres alot of little things that can cause this.

Im not sure if when I rev engine it gets louder because the battery is dead... Jump start anyone? //content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif
