  • Audi A5 – Subwoofer Upgrade

    Posted by Toids_DIY_Audio on April 19, 2020 at 4:17 pm

    Hello Gents,

    I have  Audi A5 and the Subwoofer is absolutely appalling and needs replacing.

    Currently this is the subwoofer that is installed. Its using my interior as a IB system as the magnet of the subwoofer faces up into the cabin.


    So as I have discussed with Toid, We can fit any 10 inch subwoofer into that shelf magnet into the boot.

    The cars boot is 465 Liters of Air according to the book.

    Im not looking for crazy bass just this sub seems to make horrible noises on certan tracks.

    I was planning on just sticking a 10 inch sub into it magnet down into the boot and using a amp to boost the signal from the existing subwoofer connections.


    Some people have done this


    As you can see he fitted a 10 inch fine and matted it out.


    Toid told me 


    You have sound waves coming both on the front and rear of the subwoofer. Most people don’t think of it like that, but typically you’re going to get better sound with it firing up into the cabin versus firing into the Trunk. So the way it’s mounted right now, isn’t ideal.”


    Also that high Xmax and low FS and a good QTS would be ideal.


    Add in the fact that your trunk isn’t really a full infinite baffle. It’s just a big sealed box helps as well

    It is. It is still considered an infinite baffle. But what I’m talking about is like putting a subwoofer on the other side of a wall and using the rest of your house as the box. That would take a little bit more then the particular case that you’re using it in. X max is just the amount of movement the cone can move from the voice coil. So it has oh really generous amount of movement, which is needed when you don’t have the compression of the box


    Toid reccomended a few subs but there in the usa.


    I can only buy them from UK sites. such as and or anything like that.


    Please can somone reccomend me a subwoofer? and a Amp?


    Thanks for your time!
