Says it all in the title. I am getting hissing sound from the sound system when I go high RPMs.
Started like within last week. Haven't been driving the car much lately. once or twice a week.
I was also feeling that the battery is getting weaker.

Any one else had this kinda sound coming from the system. How did u get it fixed. Appreciate that.
Thanks.

If you have a boost guage installed near by it could possibly be a loose boost hose... happened to me once. If thats the case I suggest getting a better hose than the crapy hose supplied by some companies.

 

Nope. No Boast gauge.
Its more of a whinning sound, comes from the speakers when the radio or CD player is ON, when I push for HI RPMs.

your radio ground might have come out

 

Just got it checked from Autozone. Alternator & Battery they are both OK.
Seems like I would've to pull the unit out to check the ground.
Thanks.
