[QUOTE="keep_hope_alive, post: 7461472, member: 576029"] we buy amps all the time online that we never power up or tested before it's mailed to us. while you want to test it, you can't half-*** test it or you'll risk damaging it yourself and then you have a fight on your hands. wiring direct to the battery must be done very carefully and must be fused. the amp could have an internal short and you want a fuse to protect your battery. it takes time to test an amp, time he won't want to spend. instead of meeting him at a store, go to his house. people are more honest when you know where they live. you could charge a 1F cap and it'll turn the amp on if all you're looking for is a light. but that won't tell you if the outputs are bad. missing screws are a big deal to me. missing case screws are a dealbreaker without a full bench test.
