i Cryptic 407

Last two:
16d. House and car essentially acquired dishonestly (8) A?D?E?C?
Audience? I can see the House bit but cant see the wordplay.
20d. Like ale one left inside with no head weirdly (6) E?R?L?
Stuck with "Enroll" in mind but can't see how that would fit.

Many Thanks

16d audience (house) - Audi (car) + (f)ence(d) (acquired dishonestly)

20d] eerily?

20d eerily (weirdly) - (b)eery (like ale) with 'i l' (one left) inside
