hi guys, thinking of upgrading my audio system but quite new to ICE

- My ride: Mazda 3 2014
- Prefers SQ/SPL/SQL: SQL, but slightly towards SPL
- File format/medium used for my source: any lossless & mp3
- Music genre: any kind
- Budget: RM1500
- Setup type preferences: anything
- Other requirements (if any):

i like smooth bass with clear treble & more surround feel, already did sound insulation for my doors, HU needs to remain as stock
