Hey guys..... I just took my factory Bose deck out and replaced it with a Blaupunkt Casablanca reciever and a Blaupunkt 5 disc changer (they each take up one slot where the Bose was). But, now, whenever the reciever is on, there is a faint high-pitched noise as the RPM's increase. It gets louder and higher pitched along with the RPM's going up. I have no idea how this happened.... has anyone ever had this happen to them? Please let me know..... thanks a lot!

you are getting alternator noise, therefore, change your ground setup and get an inline filter.

I had this done by a custom audio shop. If i take the car back to them, would they fix the problem? Also, what is an inline filter?

Yes, they should fix it. Will they be able too? Tough to say. Alternator noise can be tricky to get rid of sometimes. I have it as well. Had it in my old car too. Mine is faint and when music is playing I can't hear it so I live with it as I don't want my car ripped up when they try to fix it. As for an inline I haven't tried one. Let me know if it works.

Do you have RCA cables running from your deck to an amp? That may be the cause...interference with them causes noise..I had the same problem as you and it went away when I located a loose connection.

Why did you even bother to buy a Blaupunkt, they suck! you showld have gone with something more reputable like Alpine, Kenwood, Panasonic, even Eclipse. You made a bad decision on your purchase in the first place bro.

What you are describing sounds to me like ground noise.

Check all of the following:

1) Ground connections for your stereo + amps
2) The RCA cables that run from stereo to amp must not run next to the power wire, if it does, get some really expensive monster cables
3) check for bad wires.

Mien does this also, I have a Alpine HU, hooked up to a pos 1000watt legacy and 10" kenwood 600's, I get the same squealing noise, although I was told by a local car stereo dealer that it is my amp causing feedback. I have noticed it isn't as bad when it is really cold out though. Sometimes it goes away. believe me you will get used to it, I listen to the music so loud i can't hear the squeal Also did they have to use a bose adapter? they had to for me so that the alpine hu could hook up to the factory bose speakers.

i have a pretty good soundsystem. a pioneer deck pushing 45X4 to internal components and a kicker 2302 pushing close to 800 watts to my 2 12s.. nothing but clean-crisp sound. Make sure u get good cables and they are routed properly. I hate that freakin noise.

I used to get this.

After moving my ground several times and buying a new set of RCA's, it didn't go away.

I put an inline filter I bought at Radio Shack on the RCA's.

Worked perfectly, cost about $15.00
