Building materials for built-in trunk enclosure (ideas).
|
Silver Member Username: Safe_crackerChicago, IL US Post Number: 576 Registered: Jan-06 | I am getting ready to build my built-in trunk enclosure but still haven't decided on materials yet. Should I go with a traditional mdf or can I use a plywood of some sort? I will be internally bracing it and using a good amount od adhesives with aluminum angle drilled and screws done from the inside. Once done I i will resin/glass over any forseen weak spots or edges. This is going to house a SINGLE new XXX. Thanks in advance for any and all help given! Polo.. |

Silver Member Username: Safe_crackerChicago, IL US Post Number: 580 Registered: Jan-06 | I heard that plywood is stronger, less dense and the reason most use it is because it is cheaper than plywood/Birch. If able to I would prefer a lighter material because the sub itself is gonna be 76lbs byt itself, lol. Polo..  |

If you have a spare tire well jsut fiber glass the inside of that with about 7 layers. You will want to lay down some sound deadening material over the walls of it before you fiberglass though or you'll get rattles. Then jsut lay a piece of mdf over it and seal it. |

Silver Member Username: Safe_crackerChicago, IL US Post Number: 581 Registered: Jan-06 | You guys cannot be serious! This is a sub that is approx 13.5" DEEP, that means it will not fit in a spare tire well, not even close. Also this is going to be 5cf and ported through the back deck. I will be using a small amount of glass/resin on the inside but a custom FG enclosure is out of the question. What I am trying to do is to close off the trunk area te get rid of extra space to boost spl a little and to cut down on trunk lid flex. I have it all planned out but have mixed reviews on materials. I know MDF is always used becasue it is cheap, but there isn't a preset budget here. Here is a picture similar to what I am trying to accomplish. Polo.      |

Silver Member Username: Safe_crackerChicago, IL US Post Number: 583 Registered: Jan-06 | Ya, threaded rod to hold it all in, now would the rods resonate(audibly), that is the only thing I worry about using any type of metal in cabinets. Polo.. |

Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 2563 Registered: Mar-04 | i have never noticed the rod resonating in mine or anyother installs. (use 1/2" threaded rod) make sure you put on nut and washer on both the inside and outside of the box. (4 nuts and 4 washers per rod) Lock-nut > washer > MDF > washer > Lock-nut |
