[QUOTE="hispls, post: 6908850, member: 614752"] Download some test tones. Attatch the scope to the RCA outs that go into your amp. Turn the volume up until you see the top of the nice round waves "clip" off. It'll be really obvious (I'll assume you can get the waves to stand still on an o-scope or can find someone to help). Once the top of the waveform begins to flatten out you know that's the max you ever want to turn your HU up to. Next connect it to your amp (with it loaded down with speaker) and do the same thing adjusting your amp's gain up to where the waveform starts to flatten out at the peaks. I'd reccomend doing it on the amp at a few different frequencies (30hz to 70hz at 5hz incriments) since the resistance of the sub (hence power from the amp) changes with frequency. After you've done this you can possibly juice things up a touch more if you have music with weak recording levels, but you have a better idea of the limits of your clean power. Still turn on a 100W lightbulb for 20 minutes and put your hand on it. Now picture that X10. 1000W is a LOT of power/heat. [/QUOTE]
