DIY: Under seats sub upgrade (see page 7 for the solution)

Hi everyone !

Today I started my under seats sub upgrade, not so easy...

Background
Hifi option in Belgium (= standard in U.S.)
Amp upgraded with DSP see previous post

Now to the sub upgrade

1- Seat removal (done in 5min) 4 torx and you're done, do not forget to unplug your battery or you will have trouble with the airbag etc... and need to get to dealer to get it reset. (thanks ebanul for the tip )

2- Now remove the sub cover the sub itself and the enclosure, again a few torx and done in 10min.

3- Here comes the fun !!
Left to right, the enclosure, original sub and the Pioneer

The depth of the sub is quite different, no need to say that the original enclosure will not match !






Indeed that does not fit as it should



See how the original sub fits ? nothing above the original enclosure, or the seat will not go back in place.



Use the original enclosure as a pattern.



Place the pattern received with the Pioneer. Mark the inside hole.



This is what you should get



Copy/Paste the piece you just have done, but this time mark the external pioneer hole.



This is what you should get



It fits the new subs quite ok but I'm not satisfied with the details but that's a first try. If it works as it should I will redo it better.



Time to see if it fits the car, ok for now



I need to place the sub and complete the enclosure but this is enough for one day... to be continued... grr, I so curious to hear it... tomorrow maybe...
