You know, I can't say in 25 years of car (or home) audio, I've heard someone recommend breaking in speakers...??? ok... Won't argue, but I'm not sure what breaks in with a wiring/coil assembly. It's probably still good advice, though, so people don't immediately start damaging their system by driving it into distortion.

I checked the front speakers. I think you were reading the rears schematics. The fronts at the plugs for the tweeter and mid are the same color coding, and have a 0 (zero) ohm resistance between them. It's the same wire. The rears do have 3 wires to each of the near-6X9s.

I listened to the High Energy HSK next to the HSK XLs. The mids hit almost the same, unless you have a lot of power. If you're running 150+ RMS, go XL. If you're staying well under, Hi Energy HSK will sound the same and save you about $200.

I can't turn the gain up very much on my PPI A404, and so I might kick my HSKs to the rear and then get the HSK XLs for the door. The tweeter is larger I think, so it's not 100% remove and replace.
