Hello everyone. I am completely new to car audio. Right now everything in the car is just stock, but I listen to heavy metal and it just sounds ****** in the stock speakers. So I want to install a new setup to suffice what I need, to rock. Okay so my question is, what kind of speakers, amp, subs etc should I use for a good sound in heavy metal?? I have read that 10's are better than 12's because they push harder? and also I have seen people say enclosed is better etc I just have no clue where to start, any help is appreciated. Budget, right now is around 500, but as I can save more it will go up.
