bahi , you have payed a huge ammount on your system
from subs , headunit , amp , Nice built enclosure , ( i guess speakers , spkr amps , wirings etc )
every thing stands in high end category ,
lets see when you make an impact
3 thing for qualification which you are suppose to do
1: Ear-pop up ( hesitation in breath , ordinary users should put fingers in ears and due to strong irritation he should get out of car)
2: Windshield flex ( both rear and front )
3: Wind Screen Wipers Vibration
so you have the city right???
it should happen , otherwise performance cant be upto its mark ,your box is tuned at 37hz , So playing ( Late night tip 42hz-36hz-33hz bass) it should flex every thing
