Yes, you are right. The systems I have in my car is non-standard. The only reputable brand of product I still have now are the head unit and CD changer which is Alpine. The subs are also an extra components fitted, in addition to the 6.5� rear shelf speakers, meaning that the rear shelf now have 4 speakers. There are also two front door speakers, Infinity Kappa. However the sound is not what I expected out of a 12-speakers system. What I suspect is that the previous owner has removed the original speakers and replaced it with the cheaper ones before selling off the car. Right now, I’m slowly acquiring all the necessary items one at a time, as my wallet permits. I intend to DIY the wirings, maybe during Christmas since it’ll be a long weekend and I’m not celebrating it.
BTW, there’s a very good friend of mine who’s a Scotsman and got married to a local here. He’s been here for the last 14years. I believe he said that he was from Blairgowrie, somewhere near Perth, Scotland. Please inform me when you are coming(returning) to Malaysia. I'll take you to the "hawkers" and we can enjoy the food here. Cheers.
