Good stuff buddy ;-) I don't even know, does the existing amp have a channel and output for sub already? If so nice of Volvo to include that but short you the sub ha!

You need the repair terminals part number, or which slots the pins go in to?

VIDA needed to lookup and be sure, but I think it is going to be:

30656639 - terminal with "thick" 1.5mm wire
30656637 - terminal with "thin" 1.0mm wire

Pick whichever one covers the wiring gauge needed or mates with the harness you made.
