Hi im new to the forums and i was driving my girlfriends car today and as i turned the volume up high, her car speakers would cut off completely but the subs would still be bumping. and then when i turned the volume down they came back on. now ive noticed before that her rear deck pioneers seem to be blown because once i turn the bass up on the headunit i hear this terrible loud crackling distortion coming from them at the lowest of volumes. but after today it sounds like the front passenger side door speaker is blown too and that's when the speakers cutting off completely started happening.
could it be that the head unit is going bad? or are the speakers about to blow completely??
thanks for the help. |

Are they stock speakers? Do you have a 4 channel amp running to them? You may take off the door panels and physically look at them for damage. Sounds like you have blown speakers. You may want to invest in 4 new speakers and a 4 channel amp if you're just running off of the deck. Wouldn't cost too much and would enhance the sound quality. |

ok so last night everything started working alright after a while once i turned the gain down! she had the gain all the way up!! but i didnt think it was clipping because the speakers would cut out and the bass would keep bassing then after a while the whole system bass and everything started cutting out. that's when i started thinking maybe it's clipping.
to answer your question shawn the rear deck speakers are pioneer ts g970m with no amp on them they are for sure blown i am going to put a 4 channel amp on them and replace all 4 speakers.
i wouldn't think so but do you think it was the gain setting up too high that caused the cutting out problem before?? |

Yes. For a given amp, they put out so much voltage to reach their rated rms output. Your speakers, subs or door speakers are only rated to hold so much rms (voltage/power). So say for example if your speakers were only able to hold 25 volts of power and you had the amp's gain all the way up, you may be feeding it twice the voltage or even more, who knows how much exactly, than it can handle. Doing this over heats the voice coils resulting in all types of mechanical failure. Setting the gain properly is very important. In the manual it will tell you what it should be set at for a given ohm load. For example I am getting a JL 300/4 this weeknd and each channel should be putting out 17.3 volts for a 4 ohm load. If you need help setting the gain let me know. You'll need a multi-meter which are rather inexpensive. |
