What size spades can the terminals accept? If your terminals can accept them, I like the Audioquest 1/4" spades because their semi-circular shape allows for a more secure connection if you rotate them a quarter turn or so after sliding them into place.
Spade plugs for 16gauge cables
Have been using the Home Depot orange wire and using a RCA plug has not really worked (don't think the connection to the wire was a solid one). Would like to try a spade connector but again am concerned about getting one that can accomodate that size wire. Any help would be appreciated (including where to buy it), thank, Richard
