Blaupunkt Memphis MP66 with USB Hard Drive

Having scoured the depth of the I.C.E Forum I hope this isn't a thread that has already been answered! I have a 53 plate A4 1.8T with a Concert Radio, i know its not BOSE but not a lot more, looking under the parcel shelf i can see that on the right there is a black plastic grill does this mean it does have an amp and a sub? or is there a more obvious way of knowing what i have!?

I am looking to buy the Blaupunkt Memphis MP66 with its specified 40Gb drive am i right in assuming that like the Woodstock this will be a straight swap with exception to changing the live feed so it comes on with the ignition?

The other question was in relation to the D.I.S system I have have found plenty of people saying that Blaupunkt do an adapter but no references as to where or whom!

And finally I am looking for some new front speakers with a meaty range not too worried about the top end but mid-bass would be good, any recommendations for the A4 as I can see that the speakers are attached to the door sub-frame so i should be able to get some good sounds!

Thanks in advance.

Excellent, thanks for the advice, so to take this a whole step further then, by replacing the amp for the rear sub and the sub (8" sub?) itself and running new cable from the amp to the HU Sub Output will the HU i.e. 4x18RMS be enough to run the 6.5" Speakers Front & Rear or should i amp the fronts whilst i'm there?

If so, where's best to stick the other amp or is there one that'll fit in the same place as the one for the Sub and run both without the need for rewiring on the electrical front or is it thick gauge wire time!?

Basically i'm a little afraid of cars electric, slight horror story from younger years of Fiesta ownership and not knowing my plus and minuses! if someone with a proven portfolio of work wants some evasive IRS cash then P.M me!

Andy that's great, that gives me all the info i need, i've just been looking at custom enclosures on another site and i'm feeling a blue peter moment coming on.... I may come back to you with regards to the electrical fusage side of things as its not something i'm too hot at!
