I Orderd my sub box from super crew sound and have gotten it installed somewhat but it still wont fit like it should it has 3 seat supports and the box only came with 2 so i lifted the driver and passenger side and the center post is just sitting there not supporting the seat i need help to see how someone that has bought a box from super crew sound could tell me how they installed theirs the truck has to be 1998 F150 Scab
(please show any pics)

 

take out the middle support

 

here is my old set up now i got 3 10"s under in on big box with a 1200 watt amp.

 

I have a 2000 F-150 like yours except its a flareside. I ordered a sub box from best buy that is designed to fit under the rear seat. I'm not sure if our backseats have different heights or not. It will only hold two 10" subs but no amp. My amp is under the passenger seat. A technician at best buy also had to modify it a little bit so I could fit two Alpine type R 10" subs. They have a different depth cause of the magnets. Sorry no pics. I can't find my cameras memory card usb thing.

 

mines a flareside also

i would have a pic of current set up but my truck is at the shop and my amp is under my driver said.

 

oh my bad i read that wrong.

 

i cant if i take it out the seat wobbles and the seat will bend downward causing someone to sit on the sub box it self (that is how it is now because i need another lift block for center)

 

The middle support has to come out for the box to fit if the box is one that goes all the way across. The seat is plenty strong enough in the middle to support the weight, and not to mention that the box is designed to be able to help suppost some of that weight.

 

this one is not the full lenghth ill try to remeber to get pics today

 

1) NICE NICE truck. I've got an identical one.. Just no lift. You've given me a vision. Not to thread jack but when you took the small mud flaps off did your fender flares cut off? Or did you replace them. I may just PM you on that.
2) on your sub box(s) did you have to lift the seat?

 

1st) i only took off the front mud flaps, (wish i didnt because it throws up rocks,dirt,mud,ect all over. and on the back ones i cut them a llittle.
2nd) what does "PM" mean?
3rd) no for those sub boxes i cut the carpet out. but for the ones i have now i am going to most likely have to raise the seat up. but i did have to take the middle bar off. i had to drill the welds out. then pry them off.

 

I see what you did now. There is a gap.. on the front that is there on the back too if you remove the flap. It's where the fender flare STOPS instead of going all the way down and following the body panel.
