Here's my set up of one 12. It consist of a kicker c12 and a crossfire cfa 202. The box was built out of 3/4 inch mdf and has about 1.7 cubic feet of air space. The box barely fit into the well but it went in with a little bit if force. Then I added a piece of mdf on top of it to give it that clean look. It sounds pretty good. Let me know what you think. Sorry the pics are a little dark.

 

Why did you angle the sub towards the back of the car?

 

My opinion is that it sounds better facing the rear than facing up or forward. If I could have figured out a way to get it in the well facing the tail lights I would have done that. Not much room to work with.

 

I have angled my subs back for years. I did an experiment with one 12 in a walmart box to prove the theory that it sounds better. The controls were the same song both times, same EQ settings, same speaker and box, and same amp. The first time I had the speaker and box facing forward sitting on the rear deck with the hatch closed. I played the song and it sounded decent. The second time I squeezed the box into the well facing backwards completely and it sounded alot better. It has something to do with the bass waves getting louder the further they travel(hence why we here people from a mile down the road when they are bumping). When the subs are angled back, it increases the distance the bass wave has to travel to get to the driver which makes the bass a little bit louder.

Wicked box man! You wouldnt happen to have the measurements for that would you? I want to do something like that, with one 12

 

That's partly how the Bazooka type bass tubes work. Install them facing a vertical body panel, and you can "tune" how well they sound by moving them closer or farther away from that vertical panel.

 

It doesn't matter. It's a sub.

 

i talked to a car audio installer about this when i had my first firebird and put my system in he said that when their angled toward the window the sound will bounce off of it and make it sound louder than if it was just facing u

 

Ask 10 different installers, get 10 different answers.

 

Gotta tell you that makes absolutely no sense. The only thing it will do is distort the sound.

 

The theory behind aiming the sub back is that the wave length of lower frequencies are longer in length than higher notes. by aiming it back and up, you're giving the wave more time to develop before it reaches your ear. Its more noticable in hatchbacks because there's no divider between your sub and your ears. It won't make a huge difference in cars (since you're not picking up much distance), but every little bit helps.

Not the greatest example necessarily about this topic, but a good start:

looks superrrr clean love it

 

Thanks! That's what I was going for!
