20-30% boost on the sound quality of my speaker(i change my speaker. not using the stock anymore). with the rubber sound proof i already reduce the outside noise. after add the soundproof mats. another 20-30% improve. less 10-20% tyres noise. engine might have a bit like 5% noise reduced.

now go over pot hole less noise too... thats my experience for now... i will condition to do the sound proofing from time to time until i am satisfy.. might not be as good as bimmer... but at least 80-90% similar.

yeah.. take about 1K enough for all 4 doors, tyres and rear can already. but advise u change the speaker also... the stocks speakers really sux big time...

dont say only proton only need sound proof. i saw a brand new honda civic also doing the sound proof there with me. and also 1 AMG as well..
u no go help out mer?

rubber for sure cheaper... but 4 door sound proof is highly recommended.

speaker depand on yourself. test it before u buy. warranty void for speaker... no cable cutting.

no problem... but in return.. u must bring the gal faced on your avatar along wor....

his casewasnt the first. few weeks back someone also. he drove to cose and change something. now ok already. use the search function get the case outsee what cose change to resolve the engine can not stop problem and bring to cose fix it immedialy.
preve just too new. shop need the diagram and the connector to know how to change it. i posted th coonector here before. go get it out and save a copy for ya furture use.

After using liqui moly + ceratec +revo, engine become very quiet(no more lorry pick up) n the aeroplane noise is now enlarged.

My HU failed to get SD card, so nav, map, n traffic not working. Went to COSE yesterday to solve it plus 1k service. But after 6 hours of waiting, they only done engine oil changing, magnettrap n alignment. N before they passed me the car, they told me i need to make another appointment(most properly 1 whole day) just to solve the SD card slot. I feel like wrack that fella on the spot.

I m using liqui moly 10-40. Revo is kind of engine treatment n ceratec is to reduce friction and wear in engine.
