So Since the mini has been returned, not much visible work has been done. I have bought 2 7x10 inch 3-way speakers to fit under the seats and built a custome speaker board.
I came up with the idea to use bonnet pins to fix it to the car. this makes the speaker board unique and easy removable when required. To hold the pins, I used some sheet metal from a pc case whihc I had lying around and bent them to form a 90 degree bracket to fix 1 side to the storage compartment next to the seasts and the other to hold the bonnet pin. I still have to buy and amplifier and a stereo till then , the speakers will have to wait and be kept in storage =[
