If you mount speakers in that false floor panel in the luggage space, the sound gets blocked anytime stuff gets put back there.
We mounted some in that vertical panel just below the vinyl flap to the spare tire space. Sound was good, but it got blocked whenever we put stuff like camping gear back there.
I've considered building up that luggage space and putting in a lockage storage unit. Thought I'd make it the same rounded shape as the wood floor panel, but get maybe 12"-15" height. I thought also of mounting a CD changer back there.
Wait 2 12's wont fit, are you sure? What subs are they, what room is recommended for them. I'm almost certain that there is more then enough room for 2 12's, I'm going to use a single 18 when i do my install, and I definilty have enough room for that. Are you going for a sealed box, ported, IB ?
Great site. Since your going with sealed you really dont need much room. I would go with just over 1 cu ft for each driver. You can get the space by removing the plank as desribed above (set of screws), and building a custom box to replace it. Not that much work and you will still have full use of the 'trunk'. Good luck to you.
BTW has anyone measured the area under the plank and clear back over the tank? I'm curious just how much room is down there, and havent had time to do a decent job of measuring everything.
there isn't much room at all... bout 9" from the top of the gas tank to the bottom of the parcel shelf... best bet would be to either extend the box for the sub on to the rear bench, or to build a box on the rear bench itself...
most boxes that are built in to the spare tire well are custom boxes... there are some cases where manufacturers make boxes to fit specific vehicles, but i doubt any of those are for the spare tire well... it's not all that hard to build a spare tire box if you can work with fiberglass... just a matter of laying it in there, getting the right thickness, and building a good baffle to mount the sub to...
And finally, Pioneer made one for a while as aftermarket, with a built-in amp as well. I heard these new and they weren't aweful, just not enough to really make it from the trunk to the interior of the car. In a GT they might be just fine:
so does it sound good in a gt if u mount the sub in the center of the spare tire?? or has any one tried this. jus wondering since i have a/c and plan on keepin it i cant mount speakers and subs on the back panle like in most gt's. i wus also thinking about this idea they make subwoofer that u mount under ur sofa for home enternament systems i wus thinking mount a sub under each seat like two small 8's or something....any ideas any one with a/c that has found a good mounting spot???
