I've looked and looked on here and cant seem to find my exact answer. So basically i pulled off the door panels and front speaker, and was going to see if my 6.5" RF would fit but they dont. Its a little big. I dont mind drilling but i wanted to ask if it would fit in the door without having the tweeter stick out and keep the doorpanel from coming back off. Also; I have a RF sub rated at 300 Watts. If i add a 300 Watt amp, would my alternator and battery have a hard time with it? I don't want to do any modification if not nessasary. Oh also, i looked at my battery yesterday and noticed it was a RV/Marine battery. Is this alright?
