I’m pretty new to audio install and am upgrading my system. I currently have a 2 JL 10w1s that I’m upgrading to sundown sa10 classics. I currently have a skar rp1200.1 that I will be keeping until I can upgrade my electrical and then run a bigger amp. I have an o scope and dmm and when finding max gain before clipping on amp on 50hz tone I got 52 ac volts. This just had me confused as wouldn’t that be over 2500w? So I guess I’m just wondering how to max out the power from my amplifier to feed these sundowns until I can upgrade.

52 volts at how many amps?

 

[test13371997]

34.64VAC with a 1 ohm load

I’m not sure I’ll have to check tomorrow. How many amps should I be at?

 

[Denver21drake]

34.64VAC with a 1 ohm load

I understand that’s what it should be I just am unsure why I can go to 52 without clipping a 50hz test tone

No load.

No load.

Makes sense.. no resistance makes it easier for amp to produce power is what you’re saying right? So then how does a tool like a dd1 not destroy amps? I haven’t ever used one but I was always under the impression that you use it with no load and turn your gain til the distortion light comes on. Same as what I did with an o scope.

If you've got no load you tune to the target voltage, not clipping. In order to tune to clipping for your ohm load, that load needs to be connected.

Awesome thanks for clearing that up! So really the best way to make sure I’m getting the most from my amp would be to hook subs up, run the test tone, and then use o scope to set gain to max before clipping?

you can use large 4 ohm resistor to load the amp outputs, but only run those test tones for short amount of time, like 1-2 seconds at a time. then give the amp/load resistor a break. you will be generating a lot of heat. if you are using a scope you can trigger with "single" positive 20V trigger (or something like that) to capture the output, during the 1-2 second time.

also if you do this type of thing, you need nice power supply that can source maybe roughly 100A.

something like these.... for the loading resistors.

i would especially try running with resistors before running with the sub, since you are learning.
