This setup will easily run off a Symphony or Concert Headunit and fit in both Bose and Non-Bose cars.
(I am currently running it off my Concert HU in my 99.5 A4)
The Speakers
MBQ DSD210 4" components (for the front)
MBQ DKD 116 6.5 speakers (for rear deck)
The Amps
Alpine MRP-F240 4 channel amp
Alpine MRP-M350 mono amp
The box:
Custom made by a professional shop to fit the B5 sedan trunk. It fits perfectly snug, no mounting harware required. It does not shift AT ALL.

Right now I plan on keeping the sub but not the box. The box can hold any 10" sub and is perfectly sized for a JL 10w3.
This system would be a direct plug and play setup. And will save you the time and trouble of piecing together your own system (anyone who has done it, knows that speaker shopping can be a royal PITA).
I have had the system for 6 months. And still have all the original boxes. I don't play my music excessively loud. I love the setup but I have decided I want something different. Anyone local is more than welcome to come hear it.
The cheapest you'd be able to build a similar system (without buying the cheap refurbished junk on ebay) without the custom box, would be around $800. I'm willing to sell everything- all wires, speakers w/mounting hardware, box,and amps- for ~$600, I am rather flexible on the price though.
