Speakers & Deck Question

[myndgone]

Hey all,

I traded my car in for a '99 540i last week and was wondering if it's possible to use some (or all) of my speakers, amp & sub in this car...
I have 2 5 1/4s, 2 tweeds, 2 6X9s, 6-channel amp (all Clarion stuff) and Kenwood's 2 12" sub box.
Also, is it possible to install the aftermarket deck to replace the stock tape player? (also have a 6-cd changer in the trunk).
Your help's appreciated.
Thanks!
