Brabus Sub Fitting
About the Brabus sub, what it is, where it goes, how it fits, what is in it and more.
Here is the Brabus under seat sub woofer. It's a fairly basic design that
retails for an obscenely offensive price of about £350, paying for the name?
If you pay full price, you are a mug and you will be disappointed.
I got mine second hand for £100 which is all it's really worth.
If you can't get one for this price, consider a 3rd party alternative.
It's a ported box design, the metal extrusion on the back is the amp.
On the end you can make out the single control that alters the output.
On the other end of the amp is the power and speaker socket.
The speaker is 16.5cm (6.5 inches) in diameter and 6cm deep.
Held into the 12mm thick MDF fascia with four screws.
Both the left and right channels go into the sub separately.
You can see it's not a very powerful speaker, unusual impedance as well.
With the aluminium extrusion removed you can see the amp.
The amp has a bass filter built into the circuitry.
Fitting The Sub
This is the only thing it has over any other under seat sub, the fitting is easy.
It is a case of plug and play at its finest, let's take a look at the cable.
Pull out your stereo and unplug the two main connections.
Remember your radio code before you do this or it will be a pointless mod.
Take the white plug and push it to the back of the stereo hole, it needs to be
pushed over to the right so it emerges under the dash in the right hand footwell.
Pull the excess wire through. This now needs to be threaded behind the panels and
under the carpet.Remove the clipped insert (circled red) by pushing the centre pin out.
Pull back the plastic panel and route the wire behind it as shown by the dotted line.
The wire will now emerge from the bottom of the plastic panel.
Pull the panel back again and push the white under the carpet.
You will have to lift the carpet on the other side and reach in.
Pull the excess wire under the carpet. Replace the panel and the clip.
Tuck the connector and spare wire under the carpet and under the seat.
Push the seat all the way forward and reach under the carpet and pull the wire out.
Near that area there should be a precut hole in the carpet,
push the white connector back under the carpet and through the hole.
Put the bass box into position and slide it all the way back.
Plug the white connector into the amp on the left hand side.
Go back to the stereo hole. Plug the black into black and brown into brown.
Plug the light brown and the grey connectors into the back of the stereo.
Slide the stereo back into place, turn on the car and test it works.
If it is working properly you will see a green light on the amp.
Adjust the bass trim on the right side of the amp to your preference.
Securing The Bass Box
Surely you don't need words or pictures to explain this. Take the hook side of
velcro and stick it to the underside of the box. Lift the sub in place and set it
down on the carpet. The velcro holds the sub in place.
Nuts And Bolts
Accessing the nut at the back is too tricky unless you tack weld/glue them in place.
Not the original use for these clips but they work really well so I'm sticking with these.
These are used to secure speakers to thin panels such as door cards.
With all four in place, slide the sub in place and screw the sub in tight.
You may find that washers are required to stop the screw heads pulling through the sub face.
I Want To Make My Own
Mogwa wanted to see the dimensions to judge space and possibly make his own.
I had actually taken dimensions of it before fitting the sub, so here they are.
