Hello! I'm new here .

My radio (CD player to be exact) in my Cheby Impala 2000 is broken. I would like to change it. However I think I would like to install some aftermarket radio.

My question what parts/connection etc. I need to replace stock radio?

I know I need some way to mount that radio in the dash, but what else I need?

Thank you!

PS. In that particular car... sound is really flat, bass is not existing. Do you know what can be wrong?

Ps. Sorry for my bad English...
