2008 Silverado OEM Stereo ?

**emtJoaquin** · 01-23-2009, 08:53 PM

Hello All ! I am new to the forum and a new 2008 Chevy Silverado owner . I have a ? maybe you all can help me with . I recently replaced my OEM factory door speakers with 6.5 Alpines and added a fosagte sub and amp . I am now getting a hiss or feedback when playing my ipod or cds . My truck came with six speakers , 2 on the door , rear panel and two tweeters on the dash/windshield frame . It is a LS and I can not seem to find any info on this OEM stereo . Are these tweeters decent or should I replace and second has any body had this feed back noise or have any idea what it might be ? Best Buy did the install . I am thinking of replacing the head unit also .

Thanks ,
Joaquin

Does the hiss get louder with engine RPM? do you still have stock radio or aftermarket. Best Buy could be your answer too, they suck for install.

I hadn't thought about this but he is one to something you could be getting feedback from the motors own electricity.

It gets louder as I turn the volume up . It is the factory stereo installed . It only does it with certain tracks on my ipod and cds . For instance as a new track is coming on I hear it . It sounds like a fuzz , hiss sound . Like a cassestte tape use to sound . I'm thinking maybe it's the ipod . ???

I went to Best Buy thinking you get what you pay for and they are pricey . I am not totally sure they do the best job . I bought everything name brand , rockford fosage amp kit and such . For what I paid for intall and parts I could have gotten it for free on Crutchfield I found out last night .

Crutchfield is great, if you know what you are looking for order it from them. Pretty much everything over 129 is free shipping and free install gear, thats just their deal. And if you have questions you can speak or chat with online advisors. As far as your IPOD hiss check how the song is imported, it needs to be 128bit rate or higher 128 is cd quality.

it sounds like someone ran the power cables with the rca's on the same side. what do you think guys?

**vncj96** · 01-30-2009, 11:56 PM

If it was interference from power lines to close to the RCA it actually is more of a wirring noise, like very faint sirens not so much a hiss, but like i said earlier if Best Buy did then who knows, THEY SUCK!

How would I check the bit rate ? Thanks

if it gets louder with volume and not engine RPM's, and its only on SOME songs on your CD's and ipod (and im going to take a gamble that the CD's are burnt), then the mp3's that you downloaded are crapy quality. alternator whine wont only happen on SOME songs, it gonna happen all the time (and its VERY RARE when only a sub amp is installed). sounds like bitrate problem to me... by the way, i am an installer at Best Buy.... We don't all suck....however, i have experienced, first hand, some really crappy jobs from best buy....hope you get it figured out! good luck!!
