[QUOTE="Jeffdachef, post: 8535835, member: 650438"] Its better to set your gains by heat and ear with the gear you have. The multi meter method only works if you have a true to output rms amp. That amp only does around 400 actual watts after impedance rise if its lucky. Sorry to say. You also need to analzye all your music on audacity to find out what test tone you would use to tune the amp along with creating such test tone. Sounds like you used a 0 db test tone which basically guarantees you being pigeonholed out of a lot of output. I dont trust the multimeter method too much to honest. Its a passive way of setting gains and that produces junk results imo. With the ear and heat method its way better and safer imo. Play your hardest hitting song. Turn the gain up till it stops getting louder. Then back it off a notch. Then play music for 5 mins constantly monitoring the amp for changes in temperature or smell. If they stay cold, you can turn it up. If they get hot, turn it down. If they get lukewarm to moderately warm, then you are at a good balance. Clipping doesnt directly kill subs and amps. Heat does. Manage your heat well will make your gear last long and give off everything it can put out. Each song will require different clicks of volume with the bass in each recording varying greatly. Keeping up with this is called active gain setting which ensures max output on any song along with keeping gear safe. [/QUOTE]
