All pros n sifu pls help me... I just got a 2nd hand wira n very urge to have a better sound in the car... Unfortunately im still a student so nid a very very low cost for doing all this things... When the car comes it came with a 6" rear speaker n 2 tweeter on top of it.. Front there is a 4" speaker on de dashboard... Then my dad added 2 tweeter infront... So, total 4 tweeter, a pair of 6" n a pair of 4"... The tweeter is connected to de 4" speaker then the 4" speaker to de player... (sori if i made u all hard 2 understand cause i dono at all about cars. Im totally a newbie..).. But i tawt of adding another 6" speaker on de front door.. I dont have any crossover or amp.... Is there anyway to do it? Do i have to cut a hole on the door panel or i have to get a new door panel wid a speaker hole on it???
