well i bought this car 0 meter in April 2007.
all of the setup costed me 70K+ including wiring and fitting as I had purchased all the equipment brand new. I dont exactly remember the cost of the equipment piece by piece.
This cost does not include the cost of capacitor as i got it from Dubai this december.
All the speakers and mids are getting power from amp as i have turned off the low frequency sound (bass) in the amplifier and the bass is only coming out from the woofers.
Secondly there is no spare wheel in the car for this i have replace the stock tyres with michelin tyres and have kept an air pump in the car in case of emergency.
