Crossovers and Amps - Active / Passive Hybrid?

[ratten46 0]

I'm about to install my system, looking around at the stuff I have sitting around, and I started to wonder if there may be a better way to do this. Here's my plan:

PG RSd 65 components in Front

2x Sundown SD-1 (the old 8 ohm ones - which creates part of my dilemma) sealed in 1.5^3ft.

Sundown SAX-100.4

So, the original plan was simple, run the components off the front channels using the passive XO included with them. Run the subs parallel off the rear channels of the amp. Lots of flexibility with the subsonic filters, bass boost, active XO in the sundown, as well as some basic stuff on my HU. Simple right?

Then, I realized I have this old RF 200a4 sitting here unused. On paper, it's 25x4 or 100x2 bridged - in reality, it does more like 45x4 or 160x2. So....how can I make the best use of this equipment?

I thought about running the subs from the bridged RF channels, but then remembered the 8 ohm thing. Probably not a good match.

I could use 2 of the channels to run the tweeters, giving them a little less power, but I would have to run them through the passive. Or, I could bridge them and run the woofers - again running through the passive - using the HPF on my head unit (63/80/100/125 options). Either way, the other set would be run off the 100.4, using the active XO on that amp.

So...are these options worth the hassle or expense of the extra wire, distribution blocks, fuses, etc? Or should I just stick with my original plan until I can buy a better amp to run fully active? Opinions please?

I'd just keep it simple and do the one amp. Then once you want to run fully active, trade the Rockford off for a different amp to run the subs and use the Sundown 100.4 to run active to the comps.

That's kind of where I'm leaning...to avoid headache. But I've never heard a direct comparison between an active and passive system on the same speakers. I'm not sure what I'm missing out on. Does anyone know what the passive crossover frequency is on this component set anyway?

If nobody knows, try emailing PG. I got an answer from JL when I emailed them about the XR crossover points.
