Ok, a couple years ago I got a set of JL XR 650 csi speakers and a set of JL XR 525 csi speakers on ebay. Recently I noticed that the crossover they sent me with the 650's belongs with the JL coax speakers. The crossover that came with the 525's is the correct crossover. I recently got a new car and I'm planning to only use the 650's in my front door, and I was curious if the crossover from the 525's would be the same (interchangable) as the one that was supposed to come with the 650's, or if I was going to need to find somewhere to buy a set of the proper crossovers.
