Compressing Music Files For Thumb Drive In Car


I just bought a new Jeep Grand Cherokee and the sound system is excellent.......for a car. I have a ton of music in JRiver, and most of them are large files. I'd like to compress them for my 128 gb flash drive. I think I could fit more music on it, and the lowered sound quality for be fine....because it's a car stereo, right?

Can I do this? If so, how?

Thank you all in advance!

DPpoweramp is excellent, but I don't think you need to buy it. Do a search for free audio trancecoder for whatever OS you're using. You shouldn't have any trouble finding free alternatives.
You most likely will need either mp3 or mp4 files. Also, depending on your car, it may or may not be able to read and/or search files. Start with a couple of songs,then try a couple of folders and build from there. My final issue has been that many cars can't handle big thumb drives. Play with an 8gb first. Once you figure out your car's system then go bigger.
Free version of media monkey works well for bulk file format conversions but has learning curve. I used it to covert 1000s of files from wav to flac but does MP3 compressed also.

Dbpoweramp has cost but probably more user friendly. That's what I would use now.
I have a 2014 Grand Cherokee and the manual says that it will accept a 32 gb. card also it will only play mp3 files I created a folder of the mp4 songs that I wanted then converted them to mp3 works fine.
