They will take more power to run as you'll have four bulbs working rather than just the two on mainbeam,but this shouldn't be a problem to be honest.It sounds more to me like your battery is suspect.Did you have the car running when you had the lights and radio on?.
I'd rather push my Alfa than drive a BMW....
