[QUOTE="bigblank69, post: 8654248, member: 571469"] Seeing as I have a ton of experience in this department... let me be the first to say your friends are idiots lol :) A 30-40 amp PSU will be more than enough to test functionality of any amp I have seen. Most I have seen a amp pull at idle was 3 amps. Most come in at about 1-2amps at idle, and that usually is dependent on if it has a internal fan or not. Most I have ever seen a amp pull at turn on was 17 amps, and that was a 2800W Class A/B amp. Most amps there is little to no difference between Idle current pull and turn on. [/QUOTE]
