distortion

[montoya 0]

I just recently bought new speakers and hooked them up to my 100.2. The first week everything went fine until about a day ago I get a random noises coming out of my speakers. With the sound completely down on the HU and even a different mode with no audio source selected I get this high pitched whine or sometimes clicking coming from my speakers. Once I hear it I shut it off immediately. I checked the ground, remote, and power wire and they are all hooked up and connected fine. All the speaker wire seems to be intact at the back by the amp and upfront by the actual speakers, but I haven't checked underneath the carpet yet. If I turn the volume up on the HU the music still comes through crisp and clear but the whine is still in the background being out powered. Any ideas what could be wrong before I start digging up my carpet to check for some sort of error somewhere in the wire?

What kind of head unit do you have?

Just a new cheap pioneer one that I bought from best buy while my Alpine IVA-D100 is being repaired. I bought it about a week ago so its almost brand new.

Pioneer is pretty infamous for this type of problem. It will likely go away when you get the Alpine back in. Likely there is an internal RCA ground issue in the head unit.

In the instructions it gave you a clip to ground it directly to the chassis but we just cut it off and hooked it to the wire ground that would normally go into a HU. I guess I'll throw in my friends HU and see if it works, it's been under thirty days so hopefully I can make it seem like it hasn't been used.

Take a set of rca's and hook them up to the source unit in a friends car and take the other end and hook it up to your amp see if the noise goes away. Also unhook the second ground wire off the chassis of the source unit and use only the ground wire supplied in the source unit's harness. Hook the unit's ground wire to a well isolated area that has a good ground potential in the car ,other than the O.E.M point provided by the manufacture of your ride.

Is the noise there with the rca's unhooked from the amp? last ,does the wine go up in freq with higher rpm's? What kind of rca's do you have, are they running across any power wires /ground even at the amp (in other words is there a birds nest in the trunk).Are your speaker wires running along the driver side of the car.

PioneerAndy, thats good I like it. I was going to get the new alpine CDA 9887 but my buddies at Sound Check swear by the pioneer 7800 and 9800 so I had to give it a try.
