Default Which amp?

I am looking at building a sub woofer amp. Its input is via a pre amp output (uses rca type lead). Is there an easy way to measure the output from the main amp? It would only be used for a 70watt sub woofer until i build another one, so it needs to have plenty of power.

I would like the following:
Adjustable volume
Adjustable crossover
Proper off switch (not a standby one)
Works in Australia


Is it possible to have a display showing the output of the sub woofer amp?

Thanks in advance for any help!!
