I've just ordered JL XR650 CSi components, and I believe I'll need a spacer. I'm guessing because Crutchfield says they won't fit, and the fitment thread says the VR650's need a 0.5" spacer.

The only place I know of to buy a Z speaker spacer is ZEnclosures, but those are 1". Anyone know where I can get a 0.5" spacer? And what hole center do I want?

 

get 1" incase you upgrade later

5.56 in. / 141.3 mm

 

1" will be fine. Or you can make 0.5" with some 0.5" mdf and a jigsaw.... I never turn down an opportunity to buy tools.
