Fireing the sub up rather than back
I have very limited vertical space in my trunk (06 cobalt). About the tallest box I can fit in through the back seat is 15", and the sub is 15 1/2 tall.
So im either going to have to put an angle on the front of the box, and try to keep it firing toward the back, or face it up and have no real problem in calculating volume/making sure the magnet will not hit the bottom of the box... Most boxes I see fire toward the trunk, and what my question is, Are there any disadvantages to having it fire up? |

i know of none |
They face the sub towards the rear because the sounds revurbs off the rear, and heads to the front. Which in turn makes it louder.
You can fire up, but it won't be as loud. Although I've never even sat in a coalt, so I don't know what the trunk looks like. I say try it anyways, either way you will have bass. It just won't be as loud. |

i know of none Basically it all depends on the woofer being used, and if it will perform to it's fullest if mounted firing up... Mark |

Im leaning to putting an angle on the box, I got all the tools for woodworking and none of this should be a real problem. I could even assemble it in the trunk haha, that would be a perfect theft prevention solution :smilie_da |

driver sag:
http://www.adireaudio.com/Files/TechPapers/DriverOrientation.pdf traditionally, the better trunk vehicles have had either the enclosure firing rearward (here it is important to make sure there is room between the enclosure and rear wall and the enclosure and trunk to keep from muffling the reverberation) or they fire forward with a baffle that seals of the rear of the trunk altogether. if you mount firing rearward, try playing with a bit of corner boundary loading witht the port (if in a ported enclosure) firing 90 degrees opposite the driver. |
