I purchased a Micro Ti 5.1 speaker system from Dubai with the Tr-1 Subwoofer. I would like to use this in the Toyota Innova car in India. I note that the power supply to the sub woofer is 230 V. If someone has done this before. Can I find a point within the power supply unit wherein I may be able to use the 12 V DC of the car. I could also dispense of the heavy power transformers inside. I understand that on opening, the warranties will not hold good. Even then I would like to do this modification. Request to provide some assistance to do this.
