Wow just saw it, quite cheap you bought~!!
you still rmb how many sheet needed for 4 door?
you use dampener?
I use 1sheet per door, 100% coverage...But from StP videos on youtube, they said 70% of coverage enough d. StP gold/bomb/silver/i-silver was dampener, use to make thin metal sheet thicker and more solid, thicker metal sheet mean to reduce vibration, so it reduced low freq resonance from outside...
If install at door, u get solid door opening n closing, clearer sound from speaker, but still can hear lorry/motorcylcle (dis u need sound insulation/absorption material and 'D' or 'P' type rubber seal). If install at floor, it reduced so much noise from the tyre....
