alternator whine in stereo
had a whine in my car stereo (VZ SV6) that made a higher pitch as the engine reved, noticable with volume set to zero. but cant tell when stereo on normal volume setting.
i have all aftermarket blaupunkt gear, and all speakers running of amps
rca down left and power down right, all shielded cables,all high quality.
anyway got talking to a plumber at work (aka* darkhorse stereos) and he recommended a 4 gauge earth cable going from the neg battery terminal to the body as a booster, he said that most modern cars cables are made to factory OE specs, and when upgrading stereos, earth cables need to be upgraded aswell.
did this any whine is GONE!
WOO HOO
Yeah, decent installers will always upgrade the ground when installing an amp. No point having 4ga power cable if stock 8ga earth is going to restrict current flow.
Check the condensor on the back of the alternater connected to the charge wire could be stuffed

most engine noise is cause by a faulty unit or amplifier. then the wiring. first try a brand new rca, if still there try a another amp, if not try another head unit. If still there, then you will need a engine noise reducer, best one i have used is a mas power one. good luck.
Aint no family cruiser!!!
my parents old hilux used to do that i thought it was kool
Going where no late model stato/caprice has gone before.... GAME ON!!
check the Hp/LP setting on the amp as well

hey cafo can you explain why the hp/lp setting causes engine noise. ???????
its a great feature on rockford amps!Originally Posted by luke0011
Everyones a SMART ARSE! --- HP/ LP switch over --- well if you have a poor install and have noise coming though on the amp then to test it switch from HP to the LOW PASS FILTER, which normally will insolutate the noise... make it disappear!
So it is ether a BAD INSTALL - POOR EARTH or JUST CRAP RCAs and NON OXYGEN COPPER WIRES!
NO HARD TO THINK about is it -- garfa! and Luke!

you can't hear engine noise in low frequencies, when you change it to lp and you make it disappear. what does this tell you, Nothing. It just cuts out the noise. It does not tell you where the problem is. How can you add advice when you clearly do not understand what is going on. CAfo ??????????????????
Just like your response to SUB CUTTING OUT -- "" ITS A FUSE _ CHANGE IT!!""
That would be AMP NOT WORKING AT ALL!!

You don't seriously believe "NON OXYGEN COPPER WIRES" make engine noise, do you?
i keep telling you rockford amps do funny things!
still i find it funny that cafo gives an explanation of how to tell it you have engine noise when everyone else was explaning how to fix it!
i better stop now.
