Hi folks, after some years of researching and learning from mistakes finally done a complete basic sq setup.

HU : Clarion cz703
Speakers front : morel maximo [passive]
Rear : jbl cs6
Amp : Helix DB4
Mono: Re Audio dtx 1600.1
Sub : 2x RE Audio rexv2 SMDC
Soundproof : STP 2 layers
Wiring : normal RCA and Aura for front staging.

Each items bought and installed in various shops. lastly installed the amp at EA Autoworks and tuned by Howie.. Enjoying the music now. Question is if i want to upgrade to next level, what i need to do? My dream is have a nice intermediate SQL setup with HI End stuffs which can compete in any competition like EMMA but not extreme setup.. looks simple yet performs very well..
Feel free to share your thoughts and experience guys.. cheerz
