im thinking maybe my HU is throwing clipped signals above 50% volume, im gunna try it again tommorow wit the volume alot lower, see what happens.

what does that mean?

ok i just used a 0db tone and the voltage jumped even higher than the -6db it hit 50v thats a 2500w clip WTF is going on?

well i read the tutorial and it says use te -6db because if you use 0db you wont get full use of the amp

so i was sayin how the sub was making a knocking sound(bottoming out). so i decided to perform an experiment. i setup a -6db 50hz test tone put my radio at volume 35(70%) and i tuned the gain to put out 31.62 volts, which is 1000 watts. next i put in the removed the test tone cd and put the song that made the knocking sound in. looking at the volt meter some parts of the song would jump to over 40volts thats like 1600 watts, now i see why the sub was knocking, obviously that is a clipped signal. why is this happening? if i set my amp with a DMM with a test tone why am i getting a huge signal when i play a song. doesnt make sense and also makes the DMM method for setting gains seem pucking pointless.

i have a jvc touch screen headunit, is there any type of head unit that doesnt clip as earlier or is there a way to know which headunits clip at what points. at the volume it was getting a knocking sound my front speakers were sounding crystal clear

so the DMM method is pointless then?

it cant be clipping because i set it with a DMM with a -6db test tone at 50hz and it was just under the max volume... its in a 2.6ft sealed box.

hi

sealed or ported? can you elaborate on scary around 32-40hz

if i set my amp with a dmm fr 1200w theres no reason why it should clip, plus my amp is underated so i have som head room.

its a 15

i set my amp to give my sub 1000w but the amp is 1200w do you guys think it can take 1200w in a sealed 2.6ft box without any problems?

well i di some reasearch ad it seems that i should just leave the highpass off because my box is sealed and then start the lowpass around 80 and work down
