Well, the problem is that I have to underline the subject and the verb. But
if there are two of them, which do I underline? Are there two subjects?

Yes, you have to underline both:
Subj-1 Verb-1
The doorbell rang, and
Subj-2 Verb-2
I opened the door.
As Mike pointed out, there are *two* sentences, each with its own
subject and verb in this case. The entire compound sentence has no
single subject and no single verb.
Maybe it would be better if you thought of these things as
independent clauses, ie clauses that can stand alone because the have
a subject and a predicate and no preceding subordinator, eg "When",
as in
"When the doorbell rang, I opened the door".
But even in this complex sentence, there are the same two subjects
and two verbs.
