I've had my M3s for 5 years now and continue to enjoy them to the hilt. I felt it was time to add a little more lower end bass and have decided to purchase the Polk Audio PSW10 powered sub. Its economical and has all the features found in larger powered Subs. The sound too is agreeable to me although I may have liked a lower extension in a sealed sub.
However, this is where my confusion begins. My amp is a 50W x 2 custom made product which plays clean down to 4 ohm impedances. The PSW10 is however a 50W RMS rated sub amp. My plan was to hook up the speaker inputs into the sub and crossover only the high frequencies to my speakers thereby possibly allowing them to play cleaner with the sub taking on the entire burden of playing the bass.
I would like to know whether this is possible. If I hook up the speaker level into the sub, would this be 100W or 50W going in? Can the sub amp handle this power? If not, I will be forced to use the RCA (line level) inputs on the sub from my amp.
Any advice would be greatly appreciated.
Many thanks
