[QUOTE="gunz4me2, post: 6950131, member: 613729"] The only downside is that it was only 30 to 40% efficient at its rated power with efficiencies dipping into the single digits at lower volume levels. I can't find the spreadsheet where one of my engineering buddies tested it, but I recall it pulling 85 to 95 amps at 500 watts RMS of output with input voltage at 14.4 volts. Well, that was when it wasn't busy going into protect because it sure as hell cycled on and off a lot in the various test tones at 4 ohms stereo and 8 ohms mono. It also averaged 40 amps of current draw to make 100 watts RMS at 8 ohms mono. Now I see why they recommended an additional battery to run one of those 5002s back in the day. [/QUOTE]
