Audiohz Posted May 22, 2023 Report Share Posted May 22, 2023 A sundown salt 4K on two sundown X12v2 d4 running @1ohm . Subs in a Gately 4.0 cubic enclosure, so tad under sized . Would you use the sun sonic or off. Got it off now only played low volume so far . Quote Link to comment Share on other sites More sharing options...
Joe X Posted May 22, 2023 Report Share Posted May 22, 2023 100% you need your subsonic engaged, the SALT 4K will put out more than 4K, not only will protect your subs but can also reduce the amp operating temperature among other benefits. The frequency you set your subsonic filter is calculated as 0.75 x tuning frequency of the box. Quote Link to comment Share on other sites More sharing options...

I have a smd CC1 was looking at setting to 25hz but many people telling me turn it off the X series can play lower no problem. Would I hear any issues before it’s to late damaged caused or best to just set to 25hz lol . Quote Link to comment Share on other sites More sharing options...
Joe X Posted May 23, 2023 Report Share Posted May 23, 2023 (edited) The SALT 4k can put out 6106W uncertified @14.3V so let's say 3000W per driver: Box: tuning is 32Hz net volume 2cubic feet per driver. As you can see you hit Xmax at 23Hz, going over Xmax produces distortion and likely coil heating. Edited May 24, 2023 by Joe X Quote Link to comment Share on other sites More sharing options...
