hey

my front door speakers have blown and i have the bose system in my 93 RX7... can i just replace the speakers with aftermarket speakers as long as they are 2 ohms? i tried 4 ohm pioneers and nothing happens (no sound). I still have the factory deck and want to keep it along with the rest of the bose system to preserve the stock look. what do i need to do and can you recommend what 2 ohm speaker to put in?

thanks a lot!!! any help would be much appreciated!!!
