I'm looking for pictures of installs of large stereo systems in a Mazda 3 Hatch. I have 2-12" Alpine Type X woofers with Alpine Type R Components to go in front and back of this car...JL Audio provides the amplification with the JL Audio 1000/1 and the 300/4. I just want to see some photos of 12" subs mounted in these cars. How much room do they take up? Are you happy with the available space? Any feedback would be great
