As the subject suggests, which is a better purchase: Alpine SPX-137A or JL XR525-Csi?

Also, does anyone know for a fact that these will fit in a 2004 WRX sedan without spacers?

Any and all advice is appreciated.

I have those very JL's... They fit in my '02. It would be too early to tell if it fit in the '04 though. But I would say yes it would as nothing changed door wise I can see. And you can always use a spacer to get them to fit if they didn't.
