I'm thinking seriously about EQ'ing my SVS, and I'll be pushing the limits of my NHT SA-2. I love that amp as it is, but I find myself looking at eBay for something in the 200-300 watt mono range into 4 ohms. My options would expand immensely if I could include 8 ohm bridged amps in my search. It seems plausible that since the sub operates infrequently enough at high levels (I don't exceed certain limits due to domestic limitations - unless those limitations are at the grocery store) one could get by using the 8 ohmer. I AM cautious enough, however, to at least ask advice before I try. Amps in question... Sony ES NAD 216THX Several others... Thanks!!
