[QUOTE="Jeffdachef, post: 8641945, member: 650438"] So i find the point where my subs stop getting louder and starts sounding like a totally different tone than what it supposed to sound like aka normally a 40hz bass drop starts sounding like a 42 or 43 hz bass drop and starts sounding different. Thats your 10% thd point which is pretty audible and thats clipping, try not to stay in that zone for longer than 5-6 seconds. I'd back the sub level or master volume off a few notches until the output is clean and the sound is uncolored. Now play for a bit like 2 mins, then 5 mins then 15 mins sessions, smell the sub's coil or the box's port, feel the sub's dustcap or if you have access to the coil, touch the coil, it should be cool to very warm but never hot to the touch, same with your amp. AKA if you touch it and it hurts to hold it longer than 2 seconds, you need to back sh*t down even more. Once you get to a point where the heat is proper, memorize that output level by heart. For every song you play, back down the head unit volume and roll up on the head unit volume knob until you reach that output level, if the bass is too strong and vocals are too weak, lower the sub level. if the vocals are too forward and bass is nonexistent, raise the sub level. simple as that but now you have a point of reference on how loud your system should be while being clip free. Do the same heat test during summer because things heat up much faster in the summer and can get a lot more dangerous with the heat depending on your state. You may not be anywhere near clipping but your sub and amp can still overheat and blow up or go into thermal protect. Heat is the actual cause of equipment death, clipping just accelerates heat build up. Thats why i dont bother messing with test tones for gain settings at all. Relying on your ears and knowing what distortion sounds like then doing tests with heat is a much more guaranteed way to get max output out of your setup without short changing yourself on output while keeping your equpment safe. Its a skill you need to build. Most people using DD-1s and test tones are literally refusing to learn these proper skills. The DD-1/oscope is good for finding head unit and multiple signal boosters aka heaunit to dsp/LOC or line drivers/EQ max distortion levels though, i give it that. [/QUOTE]
