I've been looking at how to improve my audio system since a bought the car over 12 months ago. I priced up the sub conversion and investigated the swap over of all the existing speakers including adding some in each door. It all seemed like hard work and the end result, disappointment and an empty pocket. Eventually I exchanged the head unit for a Sony "Ipod Ready" unit which would allow me to connect my Iphone via a USB lead into the front. Marvellous thing it is too and a profound improvement on the stock BMW item. However, I was still not entirely satisfied. Something was missing. The sound was crystal clear but I wanted more. I wanted to be punched in the head by punchy low frequency bass. What could I do that would provide satisfaction and scratch that bassy itch? Now lots of you are not going to like this but I don't care as the results were and still are astonishing.
Have a look at this................

What you are gazing at with incredulous disbelief is a 12' diameter 1200watt FliTrap active subwoofer. The Sony headunit has the Sub outputs already hanging out of the back and the remote power up lead to switch it on automatically when the headunit is powered up. 3 wires from the front to the back of the car and a direct connection to the pos and neg battery terminals. I can describe the technique for the head to boot cable run for anyone with the foresight to embark on the Boom Boom project.
Look at this...........

Not the best picture but you can just make out the quick release connector which enables the unit to be removed in seconds. I have also installed a couple of little brackets to hold it still whilst driving in a spirited manner.
To fit it into the boot I had to cut down the Sub enclosure as this model would of touched the suspended shelf and prevented the roof from being lowered. I also trimmed the boot floor panel to ease access to the battery and tools. A shame really as this was the only intrusive alteration to the car, however, easy peasy to do and it took minutes. look a the picture blow to see the shelf clearance I achieved with a simple hand saw.

The crux of this story is that the Active Sub cost me £60 from Ebay and that included free delivery. The quick release connector cost me about a fiver and the entire installation took about 2 hours. It sounds AWESOME!!!!! It makes your hair vibrate. I now have a sound system that outperforms my mates Porche 911 Carrera 4S Bose system. And all for about £70. Happy days.
I don't play golf and my children are adults. I shop frequently or Tesco deliver it. Incidentally,If you own an E89 you can't have one of these as it will catch on the lid.
Consructive criticism welcome and thanks for reading.
