A very nicely done mehran indeed. And the satisfaction one gets for buying a car with their own hard earnings is indeed gr8. Now read this carefully and take it in a +ve way so in the future you can further improve ur car.
Im more of a audio guy so my critics will be in this regard. u have already been made aware of hids problem.
-firstly, the pioneer 9350sd, it costs around 15k but 1-2k dosnt matte. the point is, its a good pre.
-now the 718's. all the models u see in the market are fake. kenwood stopped making these a long while ago. the 1st copies (which are considered as original cost around 7k for a pair. 14k for 2 pairs. thats another 4k u just lost there. btw theyr not the best sounding speakers. u might consider changing them.
-The subwoofer you have is a Pioneer TS-W306dvc.... It never came in two tone and was never known as a "super champion series", since the champion series label came with the newer model (TS-w307). the surround has a black fiber cloth layer over it that peels off with usage and time. Its missing from ur sub, thus that would mean the sub wasnt bought new. If you paid 16k for this (even if it came from anywhere in the world), u got ripped bad.
-The rockmars amp is indeed a 4-channel and does cost around 6k, BUT the Audioline korean amp is NOT a monoblock. its a 4-channel amp aswell and ur using it on bridged to run the subwoofer. plus 20k for a 4-channel unbranded amp is another major rip off u have faced.
-Also which cap are you using? brand and uF?
Ur audio setup (from the prices you quoted) would have costed you around 77k (excluding the cap since i you havnt mentioned the make/model).
The setup should have costed you......
1)Pioneer Pre: 15500
2)4xKenwood 718: 14k
3)Rockamrs Amp: 6k
4)Pioneer 8601: 16k
5)Pioneer w306 (new ones dont come and 2nd hand ones sell for around 5-6k)
......56k (iv added a real pioneer gm-8601d monoblock in the list that cost around 16k new). See the amount of money uv lost? Nearly 20k. No one wants to lose that kinda money.
Friendly Advice: Think twice where ur spending ur money. never trust those shopkeepers. they will tell u the shitiest of stories to convince you into buying their products. always do ur research and ask here before buying.
