Bronze Member Username: RicezPost Number: 40 Registered: Aug-07 | Hey everyone, I got bored one day and decided I need more room in my trunk. The box was taking up too much room and notice why not just use the whole trunk as a box. The design is made so the subwoofer, amps, and LEDs can be easily accessible. There will be hinges at the bottom of the front panel so the front panel can rotate. Here is my design, what do you all think about it? I think I will need help with designing so the airspace in the trunk will allow the subwoofer to hit the low frequency. http://img207.imageshack.us/img207/8977/94320179ca8.jpg http://img207.imageshack.us/img207/6973/99078090vh1.jpg http://img529.imageshack.us/img529/6526/92586723ud6.jpg http://img370.imageshack.us/img370/6657/94045650cv9.jpg http://img529.imageshack.us/img529/5177/94376089wb8.jpg |

Bronze Member Username: RicezPost Number: 41 Registered: Aug-07 | Mark - The program is Unigraphics. Chad - These are pictures of the design box inside my trunk. -The grayish black colors represent the amps and the subwoofer (it is a square solobaric). -The red color are angle brackets. These are attached to the front panel and the top side of the trunk. -The navy blue color and gray are mdf board. -The green rods are LEDs. As you can see, the square subwoofer is attached to the front of the mdf board. I know that the most expensive part of this design is just the mdf board. I already have the LEDs, amps, and subwoofer. |

Gold Member Username: BasssquaredKansas Post Number: 2211 Registered: Nov-06 | oh i see what your trying to do your talking about an Infinite baffle enclosure like they did on Pimp my ride with the jackhammer where they pretty much used the whole trunk as an enclosure well usually the sub has to be designed to work in that application and i'm not sure L5s are |

Bronze Member Username: RicezPost Number: 43 Registered: Aug-07 | SGDenny - Why would I buy another sub? Raycist - Yeah. It is very similar to the one on PimpMyRide. I think after it is done, it would look like a normal trunk with a subwoofer facing the back of the car and nothing would be protruding into the backseats of the car. Thank you for the comments. I am wondering if anyone can help me with defining the right size enclosure (trunk) for the best sound, I am thinking of something around 30-50 Hz would be great. |

Gold Member Username: BasssquaredKansas Post Number: 2212 Registered: Nov-06 | maybe i dont know what i'm talking about but i'm pretty sure infinite baffle enclosures can't be ported since the whole trunk acts like a big sealed enclosure unless of course your seats fold down in the middle then in theory i guess that could act as a port |

The backseats would be leaning on the right surface of this image. Since the trunk is a sealed enclosure, does it make a difference how the subwoofer is placed? I was thinking of just cutting a rectangular board for the front panel and not worrying about the open slots on the sides of the front panel. |

Bronze Member Username: RicezPost Number: 45 Registered: Aug-07 | Got that covered. Anyone can help with airspace configuration? |

Bronze Member Username: RicezPost Number: 46 Registered: Aug-07 | Quoted this before: Chad - These are pictures of the design box inside my trunk. -The grayish black colors represent the amps and the subwoofer (it is a square solobaric). -The red color are angle brackets. These are attached to the front panel and the top side of the trunk. -The navy blue color and gray are mdf board. -The green rods are LEDs.

Silver Member Username: Evildoughboy08Toledo, OH US and A Post Number: 109 Registered: Jun-08 | it depends on if the piece of MDF is airtight all around the trunk, meaning if its touching the top, bottom, and if you mold all around the curves of your trunk. because the back of the seats will be in front of your amps, and your sub will be right behind them, and if the baffle board seals off where the amps are from the rest of the trunk, it could get hot. amps= hot subs=hot amps (basically inside the box)+ subs= hot hot. you would find that out eventually, but i'm not sure if that is what you are doing exactly |

Bronze Member Username: RicezPost Number: 47 Registered: Aug-07 | I thought about that, but leaving some airspace so the whole may be utilized would be better. So the whole trunk is an enclosure with the sub and amps within the enclosure (the trunk). Thank you for the advise. Can anyone help me with designing the enclosure so airspace will meet the specs for approx 50 Hz or lower? |

Silver Member Username: Evildoughboy08Toledo, OH US and A Post Number: 113 Registered: Jun-08 | if you leave airspace around your baffle board your speaker will sound like crap. you have to seperate your rear sound waves from the front sound waves |
|
Bronze Member Username: RicezPost Number: 48 Registered: Aug-07 | Sounds good. The air should be isolated. Can anyone help with airspace design. |
