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

you might want to check this out for budget systems

Thanks there !!

you're welcome, as always for budget systems, local brands like adams digital, mohawk, ameron is a good place to start with. as what i read from this forums... I think you can start off with dominations buddy. indonesian brand but highly rated among ICE enthusiasts for value budget speakers. i think they have high ends one as well. Good luck researching. Always trust your ears in the end. Reviews are just a guide. Cheers

Can check at EA autoworks for domination brand bro..
