Default AV amps for use as crossovers and amps

I need to crossover between my FR125s and my 10in subs at somewhere between 100 and 200 Hz.

So I am thinking I could use 1 AVamp per channel to give me both adjustable crossover, gain, and amplification.

Option A) Find one with bass management and pre-outs / power-ins. So the routing can be done on the outside with interconnects. No luck finding such amps so far.

Option B) Find one that is relatively simple to re-route the signals inside the case.

Any comments? Anyone know of any brands where there is a nice obvious wire between the pre and power sections.

How about a pro audio crossover?

I had a Rane in college that'd do 100Hz low-pass easy...

Reckhorn used to make a well-reviewed sub crossover, but it appears to be sold out now.

I'm going in circles here!

The previous plan was: Buy an adjustable crossover, use it with 2x stereo chipamps. Then build a 2nd order pllxo into the chipamps when I've determined the best crossover point. But would the pllxo reproduce the adjustable crossover results?

See if you can find a used Ashly XR1001,I picked up a XR2001 the three way variant crossing over from the bass unit at 150Hz.
