Is there any way to rig my b&k st 125.3 (specs listed below) to power a SVS 16-46 CS or 20-39 CS–Plus. I am on a budget of about $700. I do have a relatively large room @ roughly 3,400 cu ft. The B&K amp is currently being used to bi-amp my Lsi-9's and LsiC with negligible improvement of performance. The ideal set-up would be to use my b&k st 125.5 to power the 5 standard speakers, use two channels to power (roughly 370 rms watts @ 4 0hms) the SVS and use the other channel to power the a second center channel. I think this set up would add the most "presence" to my system per dollar. The old 150 watt Yamaha dual 8" Servo is the current weak link in my system.

Since the amp is not bridgeable, you'll only be able to use one channel on the SVS. I think you'll get pretty decent performance w/185w @ 4 ohm on the NSD model, but are a tad underpowered for the Plus. However, that's an SVS call and you should ping sales or tech support the question. I've seen them tell folks that 150 watts is plenty for most rooms.

I'm sure you can get by until you can put something a bit more beefy on it.
