i just need all the sifu help, so any one of you know any reliable sound proof shop in klang or port klang? previously have some bad experience with few shop which nearly burn my car after install simple ice.

where?

it is because of short circuit and bad workmanship, futhermore alot of car accessory do not even know how to read chinese and english instruction (even on the high pass and low pass frequency they also do not know) on all the component they install into customer car. the worst is after install a ICE accessory with them later need to keep going back to thier shop for sound tuning. which i really lose faith with majority car accessory shop in klang and port klang.

i see you are also live in klang, actually i have finally find a shop in port klang (same row with the tong hung stall). his workmanship is quite good and even is one to the rock forgate dealer.
