That sir is BS. Period. Apparently you didnt fully read the comparison in caraudiomag. I do believe it was only a 200ish watt difference on something like 2500w's. I can pull the copy out if you really need me to.
65% power loss...plus impedence rise and given my voltage drop. I must only be seeing about 1000rms out of my stetsom. Hmmm.....No.
