You should ignore any advice that says you need a ton of power with 1.6s. What you really need is a good tube amp, Maggies love tubes. I powered my modified 1.6s with a Music Reference RM9 to seemingly impossible levels. But quality over quantity is the key here. Keep in mind though that the RM9 is not your typical 100 watt tube amp. It has balls to spare. If you could luck out and find a used one, this would be a match made in heaven for you.
