I need to make this decision today, I am about to get some subs in my car ,which already has very good speakers in it Harmon Kardon, which is an option from BMW. But my question is can i get subs and stay with the speakers that I have now? because if i can't i am just giong to get new speakers first, please let me know guys, I already have a new Head unit so the speakers are more powerful than stock, Car is a 02 BMW m3 if that makes any diff, and im looking at about 1200-1600 wts RMS for the whole sub setup. thanks!
