Just use a pair of RCA splitter "Y" cables, with one leg going back into the old school amp input, and the other leg going into an inexpensive car audio subwoofer crossover like this http://www.allaudioexpo.com/nav/deta...=110&tran=fgle Power the car audio xo with a 12 vdc wallwart, you probably have one laying around. The output from the car xo goes into the input of the amp you want to use as your sub amp.

Wow...that's even cheaper than the Fmods and more flexible. Good one.

That car crossover looks like a great option thank you. I will scope out a few other vendors and put one in the basket soon. And yes I have wall warts around, I replaced all my lepai power supplies so those will get reused.

How about a Fmod?

So far, all of my speaker designs have "Active Crossover Simulation" built in. No extra charge. :rolleyes:
