[QUOTE="Saint211, post: 5130867, member: 564903"] I had one of my profile ap 1040s hooked up with no load on it for almost 2 weeks and I play my stereo A LOT. Not a problem. Ive also bench tested hundreds of amps to verify they work or figure out whats wrong with them. Sometime for extended periods with and without loads. Hell, the other day I had an alpine mrp 1000 hooked up with no load for a longgggg time. Never ever heard of this "problem" Sounds like a myth personally. Maybe something else caused it? I dont even undertsand what you mean by the voltage building up. If you mean your electrical systems voltage, yeah high voltage can kill an amp, depending on design. Some will take only up to 15 or so volts while others will take higher. But you make it sound like the capacitors just keep trying to store power til they melt, which is totally crazy. [/QUOTE]
