Any mp3 encoding above 128kbps is tolerable on most car speakers, and most ppl don't hear anything wrong with a 128kbps mp3 anyway.

Either the speakers in the back of your car are crap - in which case everything sounds crap on them, or there's something wrong with your mix. We don't have access to your mix nor your car, so we can only guess. Show us the mix or test how other tracks sound in the back seat.

i never even mentioned bitrate, Rozovian. i'm not freaking talking about bitrate. i'm talking about samplerate. resampling non-divisible sample rates is destructive. and he's doing it twice. once when he resamples 44.1khz wav to 48khz mp3, again when he resamples 48khz mp3 to 44.1khz redbook. this is a) destructive, and b) pointless since he started at 44.1khz to begin with.

Unless he was using a really low mp3 encoding (<128kbps) in addition to the resampling, I wouldn't expect the quality to drop that much. Car stereos aren't exactly studio monitors, either.

Are you saying the repeated resampling alone is a sufficient cause for the discrepancy in perceived quality between front seat and back set listening experiences?

I'll post a Sample. soon. thanks everyone.

If professionally mixed music sounds good but your track sounds bad, there's something wrong with your track. That's why car speakers and headphones are indispensable parts of mixing. They instantly tell you if something is way wrong.

the hard part is figuring out what that way wrong something is.

I've done everything I can on my mix, I've all instruments, vocals and etc stereo widen.
I mix them all in 44.1/16bit WAVs, everything is properly mixed down and sounds good on my monitor speakers.
I rendered a mp3 and burned it to cd.
I've listened to my mix in the car,
it sounds good on the front seat,
but really bad on the back seat,
what could be the problem? is it because the mp3 I rendered in 48,000/320kbps is the problem? (been thinking that actually)
I'm very frustrated, stressed out and can't get it out of my mind, i can't find solutions, I need advices from you guys,
I'm very sorry cuz I'm new in this kind of stuff,

thank you and hope y'all can help me out.

During the mix process, do you switch over to mono and address issues? A mix can sound great in stereo, then you switch to mono and you want to cry. But you have to gird your loins and confront your instruments all piled up on top of each other, like they tend to get in the car.

What I do guarantee is it has absolutely nothing to do with your rendering. Most likely it's a case of your mix sounding good in the "sweet spot", and bad elsewhere.
