What car radio? - Kenwood or Anline

Hello, I am the owner of the kenwood KDC-U30R radio and I wonder if it makes sense to replace this radio with better quality sound. I am interested in something with kenwood or alpina up to PLN 800,
The speakers in the car are the hertz dsk 165 160 rear and front and the bass box on the back 2x ground zero. I expect a pure strong sound. Thank you in advance for your help. Best regards.

Or maybe the purity of the sound depends on the source? do you listen to mp3 or regular CDs?

I listened to CDs mostly on this radio every 5 years. It doesn't even need a CD slot on the radio.

This change of the radio will not do anything, rather think about changing the sound source your current radio supports AAC / MP3 / WMA listen to songs downloaded in WMA format. There will never be good clear sound with MP3.

And the bitrate is not important?

The format of the songs is mp3. Generally more adjustable and that it has a really good quality of treble and subwoofer. It can even be with bluetooth because it sometimes sells and it is lacking like auix and USB.
The main point is whether it will pay off to exchange for some better ones, since it is good and I have been thinking about it recently.

Usually WMA and AAC in radios are still supported in lossy formats so there won't be a big difference. I know because I checked all possible formats in my cde-195bt and only lossy formats work. You just have to listen to CDs or buy a flac capable radio. Look for something alpine.

Only not every alpine supports flac, remember that.

How about the Alpine UTE 92BT?
In general, a lot of people have told me that Kenwood is hiding from Alpine, even though I have a Kenwood for a long time and I can't say anything bad. However, there is some difference if they say so.

Very good radio for its price and new.

I was still thinking about the kenwood kdc-5000bt. Which is better Alpine UTE -92bt or this Kenwood?

I would take alpine because it has a cool game and lots of useful features. Eq paramvtric, full crossover active 2way + sub. Time Correction, Variable Backlight and Bluetooth. Additionally, it plays flac. This kenwood is also interesting, but the lack of a full crossover and time trial in my opinion determines the choice of Alpine.

Then I take Alpina. Thanks for the help best regards.
