Fitting a Sub to a T31 under passengers seat.


I have just fittes a BOSS Bass600 self powered Sub into my T31.
I wanted a Sub that would not take up any cabin space and would be invisible, the drivers seat has extra wiring looms so I chose the passengers seat.

The T31 has heater vents under the seats so the Sub could not be mounted on the floor and had to be mounted to the seat frame actually up under the seat (there is pleanty of room have a look)

The BOSS sub is a neat fit with some wriggle room between the frames of the seat, you need to remove the seat by disconnecting the single wire connecter under the front near the back fron adjustment level and then the cable tie holding the cable to the seat.

Next udo the four torx bolts two at front and two at back and the seat is free lift it from the car and turn it upside down on a clean drop sheet or something so you can comfortably work on it.

Inspecting the seat frame you will see some holes about 5 cm in diamter punched in either side of the seat frame, we will be using these in a minute, first bend the bracket that the wire harness connector is on forward slightly so the sub can be mounted as far forward as possible.

I used two pieces of aluminium angle cut a couple of cm wider than the gap between the seat frame, we will be mounting the sub speaker side down so they need a little bit nibbled out so the sub can nestle between them and sit flush without the speaker grill fouling the angle.

I cut the ends of the angle so I could fold a tab at each end that sat against the seat frame on the inside so I could rivit it in place, I also cut the hook loop tape supplied for mounting and used that to actually hold the sub to the angle and covered all other bits of the angle with draught excluding tape where it might vibrate and cause noise so thats every other contact point.

Its fiddly to get in but it will fit....I didnt actually stick the hook loop tape in place until I had the whole thing mounted and rivited then I stuck it in, you need to connect the wires to the sub before mounting it as its impossible once its in place...I cut what I needed and terminated it to the sub and left it flapping around until I got the seat back in.

Go ahead and put the seat back in and screw it down, locate the wire you disconnected and follow where it goes under the carpet... remove the plastic door sill trim and the passenger foot well trim, you will be able to pass the wires out under the carpet along side the existing wire and then along the door sill with the other wiring looms. I use 4guage power cable that I routed up and thru the gromett in the fire wall thats under the air cleaner box and straight to the battery (fit a fuse just before it connects to the battery...this is very important).

The audio and remote control cables I ran thru up under the dash and to my head unit, I mounted the sub level control inside the little storeage box directly under the head unit, this is also where my usb socket is for the head unit and I plug a 4gb USB stick in holding my music.

The result is superb and you would not know it was there as its not visible without peering under the seat, there is a little bit less foot room under the seat from the rear but unless you told them they would not know.

I will take some pictures when I next have the seat out as I forgot to take them during the install (yes I know)

Re: Fitting a Sub to a T31 under passengers seat.


Thanks for the write-up, Doug. It seems like a pretty straight-forward task to do, and there must be alot of space under the seat cushion to be able to fit the boxed sub! I'll have a look under the T30 seats and see if they're similar.

Not to worry about not taking photos during the process, as your description seems very precise for someone else to follow if they would like to do the same, however depending on the type of camera you have, you might be able to take some photos using a macro setting on your camera, while the seat is still in the car. You might need to use an alternative light source (maybe a 12v fluro work-light or similar) if your camera has a pop-up flash, too.

Re: Fitting a Sub to a T31 under passengers seat.


I noticed how much room is under there also, although as I have the leather seats all the room is taken up by the seat warmers - I think I will have another look to see if I can squeeze something in!

Would love to see pics!

Well Done

Yeah I agree with Tony's last comment, it would be VERY interesting to see what the ride is like sitting on a Sub. All those deep throbs and vibrations LOL. emoticon
You'd probably notice the other half wanting to come driving lots with you all of a sudden and requesting that Bass'y song on repeat all the time.

I reckon the ride for the passenger with that sub under the seat will be something like THIS emoticon
