[QUOTE="xluben, post: 1961584, member: 568852"] I just got my Phoenix Gold Xenon x600.1 today. I was unable to correctly set the gains with my Profile amp, because, for some reason, my DMM wouldn't give me a reading. With the x600.1 I get numbers that make sense, but they're in mV instead of V. What could be going on? If I just ignore the units and pretend the numbers are volts the readings make total sense (40 with gain just over halfway). I'd also like to know the correct way to set the gains since the x600.1 uses the Xe.load technology to get the same wattage from any load (1-4ohms). The amp has two sets of outputs, which I assume are wired in parallel internally. If I wire one 4 ohm sub to each output, should I use 2 ohms when calculating voltage? It has been discussed around the internet that you can get double the power from the Xenon mono amps by tricking the Xe.load and making it give full output to 2 ohms. This can be done by powering up the amp, and then hooking up the subs. I can verify that this DOES change the output voltage! I set my gains to 40 (after letting the Xe.load sense the subs) and then turned my car off, and then back on (with subs still unhooked). This bypasses the Xe.load and now my reading was 60! Very interesting, but concerns me that the gains cannot be adjusted in the normal fashion. Last but not least, when I set the gains to what I believe is not clipping (but I do have quite a few issues mentioned above, so I don't know if they're correct), I get a lot less output than from my Profile amp (which I set the gains totally by ear)! What's wrong here? With the gains turned up I can get a lot of output, but I don't want to damage the amp. With the Xe.load trick and the gains up it gets REAL loud (like I want [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG]).
