Thanks.
Also, I notice in your system profile that you have SDS Class D. Do you drive your band pass subs with them? How do they do? SQ?
Yes I do. I am using one for each sub in bridged mode (500W each), but previously I was running both subs from one amp in stereo mode (125W). The sound is very good either way, but they sound is a bit more authoritative with the additional power. These are great little amps; very powerful, low distortion, dead quiet and they run cool. I am completely satisfied with them.
