Bought these to fit JL Audio C2-650 6.5” component speakers in my lupo. Really easy to fit and gave an air tight finish that made the speakers sound stunning. I’m running them off an amp so didn’t need the connectors that came with them but if you’re using the cars wiring then the connectors also fit perfectly to car and speakers. Overall I’m very impressed with the spacers considering the cheap price and wouldn’t hesitate to recommend them to lupo owners
Adapter rings are too wide to fit behind the factory door card and the connectors included in the kit are the wrong type (2 pin not 4) so I ended up cutting and splicing the OEM wiring loom.
They are good quality although the plug adapters don’t fit and I had trouble with them fitting my speakers I brought had to put them on the wrong way so had to cut bits off
