I drive a Myvi that comes with a DVD player and GPS.
My current speakers already like "pecah-pecah", most likely coz sometimes I need to increase the volume to enjoy the music.
I have absolutely no knowledge on any "ICE" thingy

- but what I do want is nice crisp sound and music. I mostly just listen to the radio or something on the USB.
Also my DVD only plays when the car is parked - possible to get it to play all the time, parked or moving?
Appreciate any recommendations of any sort

Your DVD issue can be solved easily.
Your speaker issue can be solved easily. Knowing you can feel that something is lack in your music, suggest go for front speakers upgrade and add in an active sub-woofer.
I guess this is the cheapest upgrade, yet improve your music a lot.
