Complains, blowing top, making low, ominous sound (7)

I believe the answer is:

rumbles

I'm a little stuck... Click here to teach me more about this clue!

'making low ominous sound' is the definition.
I can't judge whether this defines the answer.

'complains blowing top' is the wordplay.
'complains' becomes 'grumbles' (grumbling is a kind of complaining).
'blowing top' means to remove the first letter.
'grumbles' with its first letter taken off is 'RUMBLES'.
