Duffman Posted June 18, 2009 Share Posted June 18, 2009 My speakers have a high pitched whine when I accelerate...then more I accelerate the higher it gets. I had a huge amp fitted in the boot when I bought the car along with ths sub but removed the sub as it was too high for the low boot...so was sticking up into the boot blind. Was going to remove the amp but it has been wired into the front and rear speakers under the carpet by the looks of things...so looks like a bit of a job to remove. I disconnected the amp in the boot and hey presto the whining has stopped...but what is the reason for this? It's a 1200w 5 channel amp so it's pretty powerful...maybe to powerful for the speakers. Also it has loads of switches and dials all over it which I do not have a clue how to set...maybe they need adjusted. Link to comment Share on other sites More sharing options...
PeteA Posted June 18, 2009 Share Posted June 18, 2009 Could be some kind of ground loop or something. I think thats basicly noise picked up from other things grounded through the chassis. You can get ground loop isolators for a few quid from places like maplins that connect between the headunit and the amps audio cable that might help. I had this problem on my old car when i had a pc hooked up to the Aux input - ground loop isolator fixed it good and proper. Link to comment Share on other sites More sharing options...
kill1308 Posted June 18, 2009 Share Posted June 18, 2009 Could be a number of things.... First question is are the RCA cables run down the same side of the car as the power cables? Link to comment Share on other sites More sharing options...
Max Headroom Posted June 18, 2009 Share Posted June 18, 2009 reach down to the radio, find the on/off switch and turn the radio off. Then just listen to the music of the engine. Easy! Link to comment Share on other sites More sharing options...
adnanshah247 Posted June 18, 2009 Share Posted June 18, 2009 its whinning because of a crappy ground somewhere. use a thicker ground cable on a more stronger source like a bolt of something. Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted June 18, 2009 Share Posted June 18, 2009 its whinning because of a crappy ground somewhere. use a thicker ground cable on a more stronger source like a bolt of something. ive had this in loads of cars always this. Always keep ground cables to a minimum in length and most importantly get a good spot. Link to comment Share on other sites More sharing options...
adnanshah247 Posted June 18, 2009 Share Posted June 18, 2009 yep! its a common issue with ICE. people put huge power cables etc for amps and then use speaker wires for ground and then wounder why it sounds so crap after they spent like £400!
