10in under passenger seat?

no.. i have the sub.  it was pretty much given to me.  thats why im trying to work around it.  if i cant work around it, then im not going to put in any sub what so ever

If you want to use it as a midbass driver, then it should be positioned in the front of the vehicle.  Don't cross it over at 2500 Hz even if the specs say it can handle it- you'll get tons of vocals which will sound nasty/muffled.  You can try crossing over at 250 or so, but much anything above 80 Hz will detract from your front stage if your sub's in the back.

It may be best to rethink your situation.

ok let me correct myself

i do want mostly sub 500Hz but i dont want to stop it frpm handling a bit of higher end stuff.  i spent too much money on my 4 alpine speakers and i dont wanna blow them.  i listen to them too loud as it is.. and most of what im asking for from them is the sub 1000hz crap so i want this really high range sub (that is going to cost me only a small fraction of what the alpines costed me) to take care of the loud and low stuff.  and it can.  so why not?  blowing this sub isnt a big issue to me, but if its loud enough to give me what i want then i just want to try my besxt from keeping it from saging.

probably my next question would be aimed at getting rid of that super low and BUMP crap that i told you guys that i hate so much.

are there any tricks that you can think of with capacitors or inductors that would allow me to smooth out the driving voltages?  id like to filter (a bit) the low end (as in sub 35 Hz).  should i jsut go ahead to a phasor setup?  going to look into some of my texts as to some values that theoretically should give me the filter curve that im looking for to give you guys an idea.  probably wont be able to get around to that until tomorrow night.

toying witht he idea of running a tube from one seat to the other to provide true volume for the suspension.. and having a second box under the other seat.  this all depends on how big the amp is that im putting under the second seat.  i was thinking of just running some of the clear flexible water tubing you can get at hardware stores.  but would this flex too much do you think?

im trying to get a 10" Xplode under the pasenger seat of my 96 sescourt.  it needs 0.7 cu. ft.  theres 0.7 ft under the seat, but when i ad the wood and the driver, thres no way i can get enough volume, even doing the trick that ive heard about (putting cotton stuffing into the box will increase the volume by up to 40%).

so my next genius idea was to have two boxes.  one would hold the driver under the passenger seat but the second would be under the driver seat.  i'd run a flexible hose between the two for airflow. 

now my only problem is, im not sure how much the flexing of the hose is going to effect the volume that the driver experiences.  i mean, i cant use solid pvc so i have to use flex hose, and because it flexes, something tells me the flex in the hose when the driver is pumping is going to effect the volume it feels.

if any one else shares my concern, or, if you think it will work out just fine cause it wont effect the system enough to worry,.. id like to hear from you.

if you think im insane, reply anyway.

before i go, those headphones u see in the movies...
