Car model : 2011 E84
Prefer sq/ sql
Prefer price range : around 500 to 600 should be good
Listening to wide range of genre of songs, including edm, acoustic and some pop

Wanting to upgrade but this is a little diff with my pre love car, it has 2 tweeter and 4 x 4inch speakers in the car, the sound quality is not so good compare to my previous car which has a entry level pegasus installed using 2 way system + underseat sub if I'm not mistaken

I need crisp / clear / what I don't know how to describe the sound..... something like clearer, not so flat

Thanks there !!
