guys,
thanx for the not so specific answers, Brother's, I won't wanna do my installation there, coz' their installation contractors are inexperience and snoblish. I had an experience with them recently with ground wire installation. you know what they did, all they do is attaching all the ground wire from the (-) battery terminal and onto my engine valve cover only, on every single nut they can find on the cover. Imagine how does it look, looks terrific coz' it looks like extra power plug cable. Quickly enough I drove back and reinstall everything all over again, in my mind 'sc--w them, wasting my time and money.
Anyway, I don't think such door insatllation would require JPJ's approval because there's no item specification in our car registration card....so, I don't worry about that. Oh yes, if I'm mistaken the price range is somewhere from RM1.5k to 2k.
Please do me a favor....to get more information, thanx.
