I just bought a 2000 ***** Am Ws6 and I want to replace all the speakers in the car but do not want to add a box or amp, I want to keep the car as original as possible. It currently has the monsoon system. I have Boston pros 6.5 for the doors ready to drop in but need advice on a 6inch woofer (has stock 6 inch woofers in the mid panels) and 4 inch rears. Please let me know if any one has this car and just replaced the stock speakers or any advice. I appreciate all help!!!!
