new car weird setup

I got a 99 bmw z3 with the harmon kardon 10 speaker setup. From what i can gather the stock amp is sending them speakers a 3 ohm signal. is there a way to use my 4 ohm speakers on this. i don't really want to spend a ton of money on the stereo right now cus id rather spend it on performance parts for the car but i do need more noise.
