Upgrading sound
 

Pretty new to upgrading sound in a car so sorry if I get any terms wrong. I've looked throughout the forum on what to do. Except I have the 23cdr which I've read is pretty different and seems to be harder to work with. Also I do not have door speakers. And I'm pretty sure the dash speakers are the base ones.
What could I do to improve sound? Not looking for perfection but would like to hear the music a bit better when cruising with the top down.

Thanks!

I bought the following and really like it. I have replaced my door speakers but haven't done the dash yet. I would recommend finding a radio you like and upgrading the dashspeakers. Someone on this site makes adapters to install aftermarket front and rear speakers. Once you have the radio upgraded it wouldn't be hard to rear speakers. Feel free to reach out if you have questions.

Here is a link to what I did. There is a diagram for the CDR-23 wiring in there too.
