Need some advise from all LYN Icer
The problem: I hardly can hear the sound from my stock HU. Due to this, I had to tune de volume till around 20+ for a decent sound hearing. But the front speaker might vibrate@buzzing if I play some bass kick music.
I assume this problem (low sound)due to my front speaker(side and Tw)

Actually I do plan to change my stock ICE, step by step..
1)Add a amp to drive front speaker
2)Change a set of component
3)Add a sub and amp
4)Change HU. For me, I keep this changes as last option, am I doing the right thing??
5)May be sound proofed the whole car
The reason i choose to do it step by step is I want to learn the different after each upgrade. I consider my "sound sensitivity" is not that good enough, so i try to adapt it first before next upgrade.
The question is-->Am i choosing a right step,from step1 till step4 accordingly. Budget wise i afford to spend Rm1500 for step1+2 and another RM1500 for step 3. Step 4 and 5 not in my mind yet
Any opinion+advise or even comment for my planning?
