First Time Buyer Help

Hey guys, this is my first post on these forums.
I am going to be soon buying a subwoofer for my car.
I have been a car enthusiast since I was a kid, but I am now just starting to really do things with my car. I recently installed new door speakers, but now I want to do a subwoofer, and I don't know if I just need to buy the subwoofer and then wire it all in. or do I need an amp also? I'm not sure if I need an amp or not.
Or if I should just put it in the trunk? where do woofers usually go?
I already have the speaker box for it all.

Sorry again, I know a little bit about engines, but car audio is a new field I am into.
And I gotta learn somewhere.

at a minimum you will need a sub, a box (that you already have), a 500 watt or so amp and LOC (line output converter) that will get the signal from the rear speakers to play the sub(s). Subs most normally go in the trunk/hatch because of the size of the speaker and the box.

Thanks a lot Paul, I just needed a little bit of clarification.

What type of car do you have? Not sure if the pic in your sig is your car.

If you're putting a sub, you will need an amp. But there are also other things involved, so let's start with exactly what are you looking to do. A general layout helps alot in determining what you need and will need to do.

what I typed will work, it may just be a little too short of an explanation

There are some descriptions on how to install stuff in the newbie thread

hey man if you need help as to what to choose or anything like that or anything that you need i wrote an article and posted it on our website if you would like to see it the link is. it willo tell you the basics and how to wire an amp.
