Amplifier under front seats.

Hi Guy's,
Have any of you fitted your amp in the recess under the front seat in an R56 Mini? I have a 2013 JCW.
Here in the UK, I think there is a space under the drives side seat??
I suppose, in the states, the space would be under the passenger seat?
Any idea how big the space is? Any pictures of amps installed in this space, would be much appreciated too! :-)
Cheers, fellas.

i tried it, it needs too much work (cutting etc). so i put it in the empty space under the divider on the base of the trunk (where they put the tyre things). it's easier and doesn't need any changes, so it can be reverted back to stock easily.

Yeah, I did think about putting it there. I was just concerned about the continuous vibration from the JL CP208LGW3V3 sub which will be above.
I wasn't sure if the vibrations would cause reliability/sound quality issues??

I don’t have sub on top of it but i don’t think it will be a problem if you wrap the amp with some sound deadening material (don’t need dynamat or something like that, cheap one would be enoguh) and stick it to the chassis with some double sided tape. Only problem i can think of is over heating for the amp, so you have to keep an eye on that.

I just put a Polk Audio PA D2000.2 amplifier under my passenger seat last week. I forgot the dimensions, but there was more room than I thought under there. There was a large piece of styrofoam under there along with the DSC module. I cut the styrofoam to fit the amp and the wires. I also put down some sound dampening material to avoid rattles. I will be taking it apart in a couple of weeks to adjust the amplifier gain and can take some pictures if i remember. What kind of amplifier do you have? Do a search for Alpine, I think I remember seeing a few pictures people posted on here.

Hi,
Thanks for the reply, I've not purchased anything yet as I want to be sure everything I buy matches/fits with my requirements. On my 'list' are, probably, front speakers Hertz Mille MPK 163.3 pro 3 way or Focal PS165F3 3 way.
Now, for the amps and sub, I want to either put the amp under the front seat in the space underneath or, make a boot build to house the sub (using the boot tool recess as part of the sub enclosure) and mount an amp either side of the sub
in the 'false floor' in the boot. Not decided what amp/sub combination to go for, as yet.

I have the Polk amp under the passenger seat and a 5 channel amp in the passenger side panel of the boot. I also have a Dayton DSP-408 in the drivers side panel of the boot. I saw on another thread that they were able to fit a JBL MS-8 under the passenger seat so that's quite a bit bigger than my Polk amp. Let me know if you need any advise, other than fiberglass work.

I just had the passenger seat out yesterday to make some adjustments to my amp; I wish I would've remembered this thread. That JL amp seems a little to deep to fit with all of the wires attached. Have you tried taking a look under there? I think it only took me 20 minutes to remove the side sill trim (remove the seatbelt bolt first), unbolt the seats (4x bolts), push the seat up into the passenger footwell (no need to disconnect anything), lift up the rear seat bottom on the passenger side to access the carpet, and then peel back the carpet.

Below are images taken from Neil_J build log:

looking at your pictures i might fit.
i simply tried to fit it between the seat rails and when sliding the seat it hit the amp.
i already started work on false floor in the hatch area,

the 300/4 is 13.4" x 9.25" x 2.36" (340mm x 235mm x 60mm)

just for grins i looked up the ms8 in your picture 11 1/2 x 7 3/8 c 2 1/8
is there another 2 or 3 inches.

can you tell me the space between the humps that run across the car.
if I had to go the last foot or so as 8ga wire to make the "turn into th amp" i would do that.
I suppose i could measure from the seat rail bolt to seat rail bolt front to back and subtract 2 or 3 inches

i could ewven mount it on one of the humps withtheh amp "mosly in the hole" (liek an iceburg" I know that it would fit that way. (i just need to figure out for me which way woudltbe the "up side"
