Thanks! I'm new to S40 forums but I saw a couple posts on bad speakers. Made it seem like a common problem.<br>So at what volume do you hear the crackling on a bad speaker?

All volumes, should be pretty obvious, like radio static while playing a cd or something...<br>you are talking about the tweeters and not the subs right?

Volvo doesn't recommend playing burned CDs on their stereo but with good quality songs you should have no problems.

(Not that playing Britney on the stereo kills it but you get the point <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0">)

128 kbps plays quite badly on my ipod / speakers, for some songs though, the CD / radio plays fine, so it cannot be my speakers yet.

Re: (SkagSig40)

The 128 Kbs is the sample rate of the music. This low a sample rate, though considered by some to be sonically CD quality, is down sampled greatly form an actual CD using a lossy compression schemes. These lossy compression schemes throw away music data. The greater the compression, the greater the distortion. This distortion starts to look like an amplifier driven into clipping (over driven). Clipping distortion will kill speakers.<p>This is why you can blow speakers more easily with a low power amp that you are trying to play loud than a high power amp at the same listening level.<p>BTW, I tend to play my system at or close to 100% without distortion. If I hear distortion, I turn it down. So far, no blown speakers. <p>You could have a blown speaker but you might also want to check your front and rear eq settings.<p>Stan

Thanks!!!<p>My speakers are stock but sound reallygood to me. Nice deep base. Ihave not played my burned CD' yet and now I may never play them just to be safe. <br>My I-Pod has music that I uploaded to Itunes from a original CD. So would my I-pod songe be better then 128 kbs? Is it safe to play my I-pod without blowing my speakers?

You shouldn't be too worries about playing burned CDs. I've been playing burned Cds for years and there is nothing wrong with my sound system. I also have a sub in the trunk and it pounds pretty good.
