Custom Rear Deck Idea - Give Me Your Thoughts

    I am figuring I am just going to cut holes in my rear deck and drop the speakers in and mount them, but I have a few questions.

    First off, my rear deck panel isnt very rigid, What would be a good way to add rigidity to the panel? Should I fiberglass it? I was thinking acoustical matting would help as well. And I was also planning to sort of mount MDF spacers onto the rear deck panel as well.

    Basically the rear deck panel is a thin piece of fiberboard, unpainted uncarpeted, so I can add either vinyl/carpet after speakers go in for a more flush appearance, so being flush on install isnt all that important.

    Now with the speakers dropped down thru the rear deck they are pretty much infinity baffle, should I build boxes and attach them to the underside of the rear deck to make the speakers enclosed?


    OR should I build boxes and mount the speakers ontop of the rear deck?

    Ideas/Comments ?

    i'm guessing you don't have the OEM holes for 6x9s in there huh? So there is no metal under the reardeck? thats odd. but yeah, you can glass it or rebuild it out of 1/2" MDF if you have the room. some dynamat (or your choice) would also stiffen it a little bit (not that much, just add to the mass) If you're trying to get decent midbass out of these (decent for a 5.25), then building boxes would be the way to go. as far as mounted on top or underneath, that will be your preference. hope this helps

    if you did boxes on top, you could do some type of full on custom rear deck, making pods for each channel and incorporating some wicked design in between (the "Pony" for example), then paint or vinyl for finish.

    there is a board that sits on a metal frame with holes in it self.

    The full custom idea is something id consider down the road, perhaps custom that sit up, fiberglass construction or something, then have an interior specialist go in vinyl, and then do pony logo stiching, but yeah, right now im going for simple.

    thanks for the help

    idk what car, but most rear decks are pretty flat and it would take a hell of a lot of layers to build up enough strength in the fglass to make it rigid. Remember that most of the strength in the fglass is in the curves.

    Most, if not all car audio speakers are designed for IB use so I dont thinkt here is much of a need to make individual boxes for the speakers. Play them IB and you should be good, but I'd def HP them at like 200hz depending on how low they can play in your car

    also.. The SQ in me wants to say "AHHHHHH DITCH THE REAR SPEAKERS"

    I;ve never been to a concert that had the speakers behind me!! What are your front speakers? I'd be more concerned with having a great front stage, including amps, and then I would work on substage. Maybe think about some 6x9" subs or 8" subs IB on the rear deck.

    The rear deck is small, its in a 66 mustang.

    I think what I will do is get a big sheet of mdf and lay the rear deck on it, mark the boundaries and redo my rear deck with mdf.

    The reason im asking about front speakers is because this is an older pair once destined to be in another car, plans shifted and now I am going to impliment these as rears.

    My front stage will be arc audio amp powered, 2006 eclipse 5000 deck (hopefully) and I am highly considering either Boston Acoustic Z6s or something by Dynaudio perhaps. Not sure what else I'd want to go with. I ditced my plans of Morel/Renaissance and dont want CDT, alpine, jl, pioneer etc etc. I will be building kick panels for the speakers.

    So I will run my rears IB firing upwards and high passed.

    For bass I am going to go IDMAX12 with eD or Arc amplification. havent come to that crossroads yet.

    I have interior sound matting and insulation waiting to go into my car. RAAMat BXT 60 120 sq ft.; 24 sq ft tacmat, 30 sq ft edead v.4 teklite, 1 gallon edead v.3 and dynamat extreme door kit.
