Hi...
Is there anything we can do to improve sound insulation for our PE...
I just read review of Autofoam but if not mistaken out PE also fill with that.. Not sure which pillar or chassis
engine noise level I can say quite loud when drive above 120kmh.. my old 2002 waja better than that(but road noise...

)
thinking to opt bitumen (raamat maybe) in the next project at my 4 doors..
Not sure its already install or not but base on my waja.. its not...
after install it can feel improvement especially when we passing lorry / 2 strokes motorcycle at highway
any idea?
for those who already done sound insulation (for persona only).. can share with me?..

shouldnt be dont have enuff power i guess...?? that the whole point of using relay in the first place right??lower power switch high power???
doubt proton made this module themselves.. most likely purchased industry grade units from some vendors ??
we need to understand basic of relay first...
basicly its just the switch with 1 way in and 2 ways out...
the problem not about giving the high power flow... but to do switching (energize the magnet) there are power needed and what I encounter during my project, i give slightly lower than needed (slightly lower than min) and the buzzing sound happen.. and its sound really like what we encounter at our persona... still high power will flow but like on/off...
we will not feel that as it really fast and voltage drop will not notice..
from the ICM board that SC show me, I can see 3 relays... and im sure its from 3rd parties...
still no news how proton to solve it..
