    How to install component speakers into a MkV Golf.

    Hey there everyone,

    If you’re a member of other car forums you might have seen our ‘how to’ threads regarding component speaker installation. Apparently a few of the members here certainly have because I’ve received quite a few emails recently asking if I could do one up here on installing three way component sets into the Golf. So without further ado; this is how to install components into Golf doors.

    Step one: Take one original door complete from factory. Remove any residue left on the door in preparation for sound deadening.



    Step two: Apply sound deadening to outer skin (although in the photo you can only see the deadening through the midbass hole you do need to do the entire outer skin – this often necessitates the removal of the inner / outer door skin and / or window mech entirely).



    Step three: Add diffuser panels behind the midbass drivers. Your midranges in the top of the door will also require diffusers if they’re not sealed units (many smaller 2” & 3” midrange drivers are sealed units).



    Step four: Attach aftermarket cables onto the three factory speaker wire pairs. The factory wires are a large enough gauge to handle up to around 100 watts continuous. Any more power than this and you’ll need to run new larger cable runs through into the doors. We tend to solder the aftermarket cables on about four inches back from where the plug would sit. This way when you sell the car you simply de-solder the aftermarket cables and solder the factory plugs right back in. Once soldered they should be heat shrunk, not taped! We also put a plug on the midrange driver too so the door trim can be removed if need be.





    Step five: Make the baffles. These take a similar shape to the factory ones so they can screw into the factory screw holes (thus avoiding damaging the door). They're usually constructed from MDF but we've made them from perspex or even 6061 alloy depending on application. If they are MDF then they should be painted with polyester resin to avoid absorbing water. The midbass one will obviously be much thicker than the midrange one.





    Step six: Sound deaden inner skin and remove all air bubbles. Make sure you leave enough clearance for door handle and lock control rods to move freely. Also leave a little deadening around the top of the speaker hole to act as a 'roof' against water when it rains.

    Step seven: Screw the midbass baffle onto the door and seal it with gap filler against the sound deadening. We usually use netserts in the large holes left when the rivets are taken out. These inserts basically sit in the hole and provide a thread to bolt into.



    Make sure you also install a gasket between the midbass driver and the spacers because air leaks out here (ever tried to run your car without a head gasket)?



    Step eight: Screw the midrange baffles onto the door skin and seal them with foam against the plastic. Again make sure you install a gasket between the midrange driver and the spacers because air will leak through.



    Step nine: When it comes to the tweeters we employ a silastic sealant to hold it in place. We do this to save damaging the factory tweeter cover. Remember the tweeter doesn’t actually vibrate that much so this is fastening method is more than acceptable. We also attach some foam to the rear of the tweeter and this is sandwiched between it and the door resisting vibration when in operation.



    Step ten: Solder all the trimmed speaker wires onto the various speakers. Don't use crimp terminals because their two best traits are falling off and creating resistance.



    Step eleven: Heat shrink around the terminals to protect them. Unlike electrical tape, heat shrink will not begin moving after a couple of months.



    Step twelve: Sit back and enjoy your new found midbass. This is what the door looks like when complete:



    So there you have it; Golf doors with components installed. Using this method you have about 80mm of mounting depth on the midbass and 40mm depth on the midrange (using varying thicknesses of baffle). If you go any deeper than that your speaker might impact the door trim during large excursions or the window at the rear end.

    If you want to further enhance your listening experience (staging and imaging wise) then you'll probably want to make a set of a-pillars to mount your tweeters and and midranges on like this:

    I hope that helps you guys out.

    Re - Dynaudio from factory

    Great thread/info doesn't come more detailed than this ! Thought about coming on as a Sponsor on the forum ? Speak to Justin Fox and Christina Fox ( suga )

    Great write-up Marty, have you done any installs in the MK6 yet?

    Are there any good options available as far as line converters go to be able to retain the standard source unit and run aftermarket amplifiers?

    Nice write up Marty, would almost try installing myself next time but would probably bodge it up.

    Apparently those diffuser pads don't fit behind the woofer in mk6 2-way setups?

    And this ladies and gentlemen is why, unless you really want to get into it, an audio install should be done by a pro so that the sound coming out reflects the money you put into the system. Great write up!

    Sounds like a good idea. Especially when one considers the amount of VW's we get through here.
