[QUOTE="Jeffdachef, post: 8517699, member: 650438"] Fk him and his products they are completely useless because its still passive gain setting. If you have any understanding about how music is made, theres too much fluctuation between bass signal strength in each recording that affects the performance of your setup waay too much for his DD-1 to have any usefulness. you are better off setting gains by heat monitoring. Just play your heaviest bass song. On the head unit, set it to around 75 to 85% of max, sub level maxed out, bass boost and loudness off and any EQ bands associated with bass keep them flat On the amp, keep the Bass boost off at 0, subsonic filter at 75% of your box tuning Play the song, raise the gain until it stops getting louder, then back it off a notch. After that just learn and recognize the bass strength in each song and adjust sub level or volume knob tomatch each song. You'll get used to it. Most important thing is to play for 5 mins at a time and monitor your amp and sub's temperature. If its too hot, back it down. Too cold, you can turn up the gain a bit. Slightly warm after 30 mins of play would be optimal An example would be, in a metal song, there will barely feel like any bass vs a hip hop song which will have a huge excess of bass. Youll want to turn the sub level down for the hip song and raise the sub level with metal. You cannot expect to have optimal sub performance with each song by just setting it once and just leaving it there. Thats basically impossible. You will have it at a safe level at best but you will be severely limited on output in every other song you listen to. Not to mention if you set the gain with a -10 db bass track and play music that has -5 or -1db bass drops in it, you'll blow your gear because that will put you into a heavy clip. [/QUOTE]
