speakers/amps sound fine until i turn my car's engine on
speakers/amps sound fine until i turn my car's engine on
then only the rear speakres produce sound and i think the front speakers produce a cannoot hear sound that makes my ears hurt, a sound tha tis below 20 db i have one set headunit ,rca cables run on the right side of car, amp power cable runs on the left side. the amp's ground cable has a isolated grounding point away from any other grounding points. the has a 15 amp fuse and so does the fuse holder near the battery the amp is suppose to be new i bought it off ebay from an audio dealer it came with new packages and amnuals |

Try regrounding the amp on something else, this time not isolating it from the others if you can. |

Sounds like a ground loop to me. Try regrounding the amp on something else, this time not isolating it from the others if you can. i grounded it on the ground that is also for my aftermarket trunk pop but i still get the front speakers cut off i check the power to battery cable and i changed the ends on the power cable so it is nicer now, but that did not help maybe i should cut my ground wire in half? or just keep finding new places to mount the ground cable? |

"Aaron Russell" wrote in message om... some cars just have bad ground lopp problems , the easiest way to eliminate it is by having superior equipment.. And how is this supposed to help with a ground loop? It is merely a potential difference, high quality gear is just as susceptiple to the problem. quality amps, and also, quality head unit with 4 volt pre-amp outs.. A 4 volt output won't really help with ground loops. however, if that doesnt work,...try changing ground points for yoru amp... make sure it is grounded to the same piece of metal that yoru ehad unit is grounded too.. You mean the chassis? A good chassis ground is a good way to go. you can also try running liek a 12 guage wire from the case of yoru head unit, to the groudn of yoru amp.. that might eliminate the ground loop.. its trial and error.. Ground loops can be a mystery, that's for sure. But most of the time they are easily solvable when you just start from one end and work your way to the other. BTW: Why is everyone looking for a ground to be a problem? Mark, any ideas why that is the focus? Les |
