I got a pair of L80T3 Xovers for my L80T's. From what I understand, they have a mixture of electrolytic and poly (or whatever) caps. Is this correct? I can't tell the difference. If there are electrolytics, would be be a good idea to preemptively replace them? If they're 20+ years old does that mean they will degrade sooner or later? If they're going to go bad, I imagine it would be easier to get them replaced now, before I install them. I don't solder but I'm already planning a trip to a service center. I have two pairs, so I'm going to try refoaming one pair of woofers and paying to have the other done.

Also, should I be able to install the xovers myself? It looks like the connectors don't require solder. I just use the wiring diagram from the L80T3, right?

The + and - terminals on the L80T drivers are the same as the T3?
