mono amp for sub

Not sure why you would want to waste an amp like the Bryston in the first place, subs need no such amp.

I use an Onkyo M-504 to drive my Vmps subs...over-kill to say the least.

The Carver zr1600 pro has a mono switch and would work well for a sub. It has a good deal of lower end control in stereo mode, so ought to work well.

That was my point although you said it much better. My Onkyo M-504 has large power meters, at 60hz. and below my Vmps subs hardly draw over 100 watts even at extream volume levels. Those power levels are peak at that!

90% of music is in the 0-50 watt range to be honest.

Something like an $2,500 Bryston for that limited freq. range is a waste of money IMHO.

In a similar situation and wrestled with this. Used 1 channel of a cheap Sony stereo which worked pretty well. Tried a DIY plate amp, not enough gain control. Found that a straight amp and the prepro's lfe +/- adjustment wasn't enough. Was leaning towards proamps (crown, qsc, etc) with a gain adjustment. I also used a good quality car audio amp I had around (hifonics zeus) with a 12vdc power supply, worked well but clumbsy configuration...

Here's what I have coming and I'll let you know how it works out.... I bought a Buttkicker amp. Class D that only responds in the 10-200Hz freq range. Said to put out 1100W into 4ohm (way more than I need or the sub it rated for) and is said to be 2 ohm stable and double power. It has the crossover and volume level control.

email me in a few days or maybe I'll follow up with how it works as a sub amp.
