clamping amp-whcih frequencys

whats the ideal range of frequencies you use when you clamp an amp? 30-60hz??? also is it pretty hard on the subs when you do this?

thanks.

idk if its hard on subs. but i was tolds 45hz is ideal

Its no harder then burping them

Just make sure your gain is set at 0db to get the most unclipped reading possible

what do you mean by this?

i want to try a few different frequencies so what is a good sweep to do

I heard 50hz is what is best to use

Tones are recorded in 0db. you need your gain set a 0db to not clip on a tone.

i set my gain with a 50hz 0db test tone if that is what you mean

Gain settings are in volts, not decibels.

You clamp your amp at your burp/peak frequency, so you can measure rise and output. Any other frequency will be misleading/irrelevant because it varies so wildly.

how do u know ur peak frequency? that was why i wanted to know what was a good range of frequencys so i could find out my peak output and rise

when you scope its not in volts. Master SPL guy

I suppose you could do it this way. It seems like it would be much easier with a TL. If you have no clue where your peak will be, you should probably test on a TL first to get a rough idea. At any rate, your peak will have the lowest output and highest rise. Below tuning very much and you'll have a VERY VERY low impedence. Much lower than nominal (what you wired to) and could cause damage.

so what frequency would give me the most output a least rise?

The worst possible frequency for your equipment and you would not be loud at all.

i have them wired to 1 ohm so obviously i dont want to have full power at 1ohm with rise cuz the sub wont have any dampining if i am correct. i just want to try a range or frequencys that will show me my output and rise.
