car audio troubleshooting help
problem: at low volume levels, the left or right speaker. goes out. but when I yank the volume up pretty high, they turn back on. sometimes it's the left and sometimes it's the right. completely random each time. sometimes they'll play for a good 5 minutes at low level before one of them goes out. and sometimes one of them goes out within 10 seconds of me having it playing at low volume. when I have the music on a pretty high volume, neither speaker ever goes out. failed solution(s): someone told me it might be the crossovers, so I replaced them. no luck. other info: subwoofer never goes out regardless of volume (basically works fine) got any ideas?

1. could be a simple wiring issue, maybe a bad ground.
2. i'm assuming you have the L and R speakers running off separate channels? If so, u might have the gains and/or crossover points set incorrectly. the fact that you can affect the situation by using the volume control also points to a "clipping" situation. are the channels bridged? you might be running too low an impedance on speakers that are designed to run at 4ohm. thats all i got right now. leaving work now, i'll check again when i get home and have time to thing clearly. |

if you tuned your amp yourself, look it over. or possibly take it to someone that knows what to do. I agree with KOD in it being a clipping situation which is not enough power given to components to function properly. Again, agreeingw ith KOD, since its random, it may just be a ground. Check the wire connection at the speaker, the amp channels, and finally the amp ground. If that doesnt work, double check your battery ground. Ive had scenarios with my sound system not working because my negative battery terminal was loose. That also caused my blinkers to work without being engaged or not work at all. The ground is a killer.
edit -- check your head units ground as well as your RCA connections too. just to see if they are split at the connectors from wear or if they are loose.

And if you grouded the amp to the chassis make sure you scraped the paint off before you grounded it, that is something a lot of people overlook.

just checked and everything's connected and grounded properly..
going to replace the rca cables.. a couple members on the nasioc forum suggested it.. also, Audio Integrations said "Somewhat rare, especially on two speakers, but partially shorted voice coil? I've seen that a time or two"

Well you do have to watch when istalling speakers in your car, because the doors are so shallow that it is difficult to space them out properly. Put your windows down and shine a flashlight into the window's opening, you will see the back of the speaker and a screw from the window bracket. If the screw is touching the back of the speaker it could throw it into safe mode and potentially mute the speaker... but that doesn't necessarily explain why it only happens sometimes and at low volumes.

i googled your amp and if i'm correct it has 4 channels? and its 600 Watts? does your amp have any fuses(probably 20 Amp yellow) you can replace on the outside? and does your amp have "Bridged" speaker inputs? (is common for higher Ohm speakers or subs) Also does it have a "protect" mode? this is common in amps when electric "spikes" into the amp and it will go into protect mode, and you must repower the amp. This is my professional suggestion, if you still encounter a problem notify me.

i think that either the wires are bad, a short circuit. or loose connection. thats what im saying. if its not any of them... then your amp was damaged somehow. possibly overheating, which can happen easily if you don't mount it properly.
