[QUOTE="IgnoreMe, post: 3573418, member: 551352"] i had my buddies under the hood. he checked battery voltage and amperage right up front. this gave me the wattage i was drawing, but it was all before the amp which didnt mean anything in terms of what the amp was putting out. it doesnt really matter what you're wired at. what does matter is how far away you are from the DCR when you test. the farther you are from DCR, the more skewed the numbers will be because of "apparent power" for example, if you are at a 1 ohm load, try to find a freq that is as close to 1 ohm as possible. hopefully you got or can make a test tone CD, and just run a bunch of freq, gathering V and A for each freq, and then do the math to see which one is closest to your DCR (ie, which one has the least impedance rise). you should be able to do this on low or medium power to see which freq, will work best, and then when you're ready you can max out the tested freq to get the numbers for the wattage calculation.
