Bray, I use two 12" 250 watt JBL PSW-D112 subs in my room(one in each front corner) and I've been running since 1998. It seems that the amps blew on everyone who bought them except me. I like my movies really loud so they get on heck of a work out, but for some reason they just keep going. I can't explain it. Sometimes I hope they will blow so I have a reason to upgrade, but they just keep going.
