Here we go...
Auto Fusion i.e, Touqheer and Anwar are good at what they do and command a premium for this. Also note that he has given an estimate actual price may differ.
In this industry you get 20 people everyday asking fo a quote, especially people on bikes looking around every store to see where they can save a couple of bucks. If money is the main concern then quality of workmanship and finished product may be compromised.
I know a lot of people who go to these guys and dont even bother asking about the price! They just select what they liek and leave the car for installation. This includes me too.
If you want total satisafaction of sound and quality of install then you have to pay for it.
Even Satya at Evo does good work, check with him. from 63k quoted the price might drop a bit but not that drastically..
Yes, the HU might be expensive but did you notice that at 63k he is also doing the complete wiring, damping, and installation ?
So to actually compare apples to apples and oranges to oranges ask him for a break down of pricing. The installation, the wiring, the damping and the audio products. This will make it easier for you to comprehend as well as give a clearer picture to others.
