sound to no sound. Head unit is still on and still playing, but no sound. Good point with the speakers. I just remember the amp giving me the code for too much current last time it happened. Again I never really changed the gain when i used amp so could it be that?

 

When you say 4 component sets, do you mean 8 midwoofers and 8 tweeters? Cuz each component set has 2 midwoofers and 2 tweeters (L and R).

If you do have 8 mid/tweeter speaker combos wired to 4 channels, and they are hooked up in parallel, then each amp channel is only seeing a 2 ohm load. I don't know about your amp specs, but a lot of amps are not stable down to 2 ohms.

Regardless, I would check for shorts (to ground) in the speaker wires with an ohmmeter. If the wire insulation is in tact, I would then see if the amp is getting too hot because lack of cooling air can cause the thermal overloads to shut down the amp.

If you remove all the above possible problems, back down on the amp's gain adjustment knob.

 

i just checked, and the amp is reading the same, "cur" meaning too much current. And it only happens when the car is tunred on. It seems to be running fine when the car is off.

Als new problem, i guess its not just dound to no sound, its also, sound to lower sound while i drive to. Im thinking its a wire in the spekaers. What do you guys think?

 

If its going from sound to much lower sound and giving you a current warning I would bet you have a wiring grounding problem somewhere... those are always fun

 

crap, here we go again, round 2!

 

 

I agree that the best place to start is to look for shorts to ground on the speaker circuits. Depending on how your wires are run, is it possible to disconnect half the speakers and see if it still has the problem?

If you disconnect (let's say) the front speakers at the amp and leave the rears connected, if it still cuts out that would indicate a problem in the rear speaker circuit. I'd then try running with just the front speakers connected and if it fails to cut out then you can be pretty sure it's in the rear speaker wiring. Then add back just one side of the rear speakers (left or right) and see if the problem returns. If it does you know it's that speaker circuit. If not, then it must be the other rear speaker circuit.

 

Good point.
