1. Burning an audio CD from your MP3's; choose audio cd format, not mp3 format! Your burner will do the necessary conversion.

2. Burn you CD's using the minimum speed your burner & disks allow. If you have high speed disks, then perhaps you should try the slower ones that burn to 16 speed. Some stereo cd players & car players don't like cd's burnt at high speeds or high speed disks. Some are also brand fussy. Best to choose well known brands even if they cost a little more ... they will last a lot longer for a start. 16 speed disks burnt at 4 or 8 speed are usually reliable!
