Post Number: 3590 Registered: Mar-06 | I was thinking about trying a new expierement and was wondering if anyone has try\seen this done before. I plan on sealing off my trunk with a few layers of sound proofing both matt and liquid. the trunk (rought guess) is about 12cu or so, what i want to do once it is sealed is make a piece of wood fitted to where the rear of the back seat covers the trunk and seal\bolt down the board with a 18" dd9500 built in, with the port being built firing into the car as well in the same board.... it would be easily removable and able to drop seat back in |

Bronze Member Username: CrossfiredPost Number: 40 Registered: Mar-07 | I've done this meny times and it can sound good. I've done about 10 installs with 4 8" woofers across the rear deck. You dont need to use all of the trunk, about 1/3 will work well. I built a wall in one install that came strait down, leaving a 3ft x 1.5ft x 1 ft. (4.5 Qubic feet) right behind the seats. Mounted two tens and it was super sounding. I like to use these eights : http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=264-854 |

Post Number: 3597 Registered: Mar-06 | Im trying to work with what space i have to make it easier; i can always add sand bags or what not in the trunk to take up some of the space (not really sandbags, but dead mass) to make the CU decrease. I have the 9500 already but need to get it reconed to a 18; i could do a 15 but i decided its easier to work with a 18 with that much space. Can i get some vids\pics of what you did? |

Silver Member Username: MesodummTri-City, Az Usa Post Number: 207 Registered: Apr-07 | I've done it several times, I have done different combo's 2 12", 3 12", 4 8", 4 10", You can do 15" if there is enough room, here has to be enough body to work with, and yes the can be made to look good and safe after if you want to sell truck after, I use diamond plate to repair bed and inside the same but I carpet inside. I liked the 3 12" and the 4 10" the best!! You will need to make a good seal in between cab and bed, camper shell places have boot material, that along with pipe insulation foam and screws and washers, lot's of screws and washers. |

Post Number: 3599 Registered: Mar-06 | Rob; its not going to be permanent, and would test my sound deadening(4-5 layers or more of matting and liquid), the baffle will mount with the same mounts the seat uses so no drilling or anything is needed. I also wont have it loud most of the time its in; probally only 1000rms or so but will be able to give it 2-3Krms when wanted. Its only test projects until i get a car for SPL but if it works good i will still keep it for drop in SPL if i want to goto a comp or somthing. |
