I have never purchased any car audio stuff except radios in the last 10 years. I will be upgrading the factory sound system in my 98 frontier i just purchased. The doors can hold 6 1/2" and there is a place for a tweeter so i was thinking components? But i dont know how those work, there is a little black box that comes with them, do you have to run 12v and remote to that box? If so i will not go that route i just want to use the existing wires to the speakers. I am buying a Alpine radio that will only have the door speakers connected to it so suggestions on speakers that will only be powered by the radio. Next is bass, right now i have a cheap amp on a cheap 10". I want to upgrade the amp and the 10" sub. I want a small sized amp since i dont have to much space, I was thinking maybe a 300w amp and no idea on sub nor what ohm i will need for it. Thanks for any suggestions! Excited to get this thing rockin!
