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?

change HU always the 1st step.

1) Change HU
2) Component set
3) Amp (4channel?)
4) Sub
5) not enough boom boom? monoblock amp.
6) up to u
7) up to u
8) up to u..
okok i stop here.. lolz
sound proof not sure which step..
the steps i mentioned above is just my 2 cents. cheers~
use the RM1500 buy a decent HU or 2nd hand high end HU.

sound proof between 2) & 3) step....but all depend on urself...

since you have vibration issue now... why not do sound proof first?
