Review on 🔌 Enhance Audio Connectivity: Metra 72-9300 Speaker Connector for Mazda/Nissan Vehicles by Oso Mears

I bought these to upgrade my speakers to 6" x 9" on a 1993 Nissan 240sx. The connection to the stock speaker connectors is fine, but I couldn't tighten them at all. onto the tab so that the connectors "snap” into place. From my observation the connector only depends on the thickness of the pins to stay in place. I can easily pull the connections apart so I decided to use a zip tie to secure both connections. This should prevent them from coming loose.
