As advised by him, I went to Toyota Islamabad Motors, looking for "Altis Inner Garnish" .. but as it turned out, it was not in stock.
Today it was not a busy day for me so I went over to Brother Madhouse ... We discussed the re-installation of tweeters. Mani Bhai's installation is very neat and nicely done. However, the tweeters need to be directed at the target person. Brother STJ suggested that we should focus them on the head rest of the opposite side.
