I am looking to install Alpine Type R subs into a BMW 1 series. It is a small sport coupe and I have been leaning towards the idea of running dual 4ohm Alpine Type R's at 1ohm at about 700 watts each. I need to know if this is going to be "to much" for the car I'm driving.... would it be better to maybe just have a single Type R?... In other words I don't want to damage anything.
