Yes. ANSWER: If you're going to do it to save weight, they only weigh a few pounds. Depends on the generation. Removing the back seats in a cloth interior 5th gen celica saves you about 40lbs. Obviously more for a GTS/AllTrac leather interior. I don't know the weights of the other generations.
it is under the back seats

The fuel filter location is inside the fuel tank along with the fuel pump in order to get to it you have to remove the back seats there's a video on youtube on how to do it just type in "Replacing fuel pump / filter on toyota celica Gt'' but the fuel filter can only be bought via internet because no auto part store carries it.
remove back seat, remove screws bottom and top of panel, remove panel. remove 3 bolts and motor arm, window and regulator will pull out.
my celica had 8" subwoofers in the front and standard 6" speakers in the back. I had a 1995
6.5" front and back
its under the back seat
The transmission dipstick on a 1986 Toyota Celica is toward the back of the engine compartment on the passenger side of the motor. It is behind the air intake hose.
Well, honey, removing the back seat of a 1990 Toyota Celica is as easy as pie. Just locate the bolts or clips holding it in place, grab your tools, and get to work. Once you unscrew or unclip them, give that seat a good tug and watch it come right out. Just be sure to handle it with care, we don't need any unnecessary drama now, do we?
4 inch front and back
I have a celica Gt 86 COUPE and in the front they are 3.5 and the back ones are 4-1/2
Good news, Toyota was thoughtful when they installed an access pannel under the back seat. Remove the back seat, unscrew access pannel (6 to 8 Phillips head screws) WALA!! JIm
