Recommendations for spade lugs for 14 ga conductor?

Are you using this just for the sub inputs?

Don't get too expensive. If you were using a passive sub, I'd recommend the WBT folding type of spades.

Otherwise something inexpensive. Check out Parts Connexion, lots of choices there. :)

Some like minimalist spades.  Below are a couple of links to the Vampire SPD spade, which is solid copper with gold plating.   Made for 10-12 awg but should be fine to crimp your 14awg Canare.

BTW, not sure if you are thinking of internal bi-wiring your Canare wires but I would recommend cross-connecting them instead - i.e., connect the two wires across from each other together at each end so two wires go to positive and two to negative.  If you need to bi-wire, do the same again and run a second cable.
