Vehicle : Hummer H1
Location in the vehicle: Subwoofers would each be inside seat base container under rear seats on each side of center tunnel
Space available (Length x Width x Height): 21" by 12" by 11", slightly irregular aluminum box structure as seen in the pictures.
Subwoofer make and model: Would like to use either an Alpine RS-W10D4 or a JL Audio subwoofer. For JL I would like the best option between the 10W7AE-3, 10W6v3-D4, 10TW3-D8, or a 10TW1-4. The structure of the enclosure dictates what I can use I think.
Subwoofer Size: 10"
Number of Subwoofers: 1 in each enclosure, one enclosure as the seat base under each seat.
Type of Port (Kerfed, Slot, Aero, etc.): sealed
What type of music do you like?: Rock, Rap, electronic, ACDC....
Is your goal SPL or Everyday Music?: Everyday music
Tuning Freq (Hz): as low as practical...
Volume : That depends on how the structure is designed inside the base I have attached pictures of...
Questions: So the seat base is an aftermarket enclosure product made to replace the seat bases in a hummer with this aluminum enclosed structure, assembled with rivets, and it is designed to fit the space completely. It has a volume of space in it and I want to have it welded, sealed, sound-treated to control reverberation and vibration, and then fitted with a subwoofer enclosure. This would give me 2 subwoofers in my Hummer H1, one beneath each rear seat. The truck is an open-top and I am in the process of sound-treating the entire body even though it is an open-top. It has hard doors as it is a civilian and I am putting an aftermarket top on it that is much quieter than the original was. The main issue is engine noise in to the cabin, which is where my focus will be with sound treating. Finishing things off, I will be wrapping it in black carpet to match the rest of the lower interior so. it as an OEM look to it like a modern vehicle, not the plasticky interior it was made with. I will be wrapping upper panels in leather.
My questions are as follows:
1. How precisely does internal volume need to be known and calculated for each sub if you know that the volume is comfortably above the manufacturer's recommended minimum and not large enough to be significantly above that measurement?
2. Are there any serious problems with building a subwoofer enclosure inside this aluminum seat base besides difficulty?
3. Of the subwoofers I listed, any one of them stand out as being good for this task?
4. I assume the enclosure would be built using mdf and/or fiberglass- I would love a fabricator's thoughts on how feasible my idea is. I know I do not have the skills to do this project, so I would like to know what to discuss/bring up with a fabricator I would have do these enclosures.
5. Would it be better to get a pre-made enclosure that comes with a subwoofer or even one that comes with an amplifier integrated as well?
Thank you for any and all thoughts on this project as I start to design and implement a full system here. I intend to have some speaker pods fabricated to hold minds and tweeters up on each side of each windshield pane, with the component woofers down near my feet, and rear three-way all-in-one speakers in the lower rear door panels I think.
Pictures below show the enclosure, its measurements, and the space It will go and some pictures of the existing install I am removing.
