I have a small power supply, something like 2-5amp output. I've got a PG crossover that I purchaced online. I really want to test it but cant until spring. I was wondering if I hooked this crossover up to my power supply just to make sure it powers up should I be concerned it may cause damage the unit since it doesnt have enough amperage for the xover. All I wanna do is power up the unit not try to use it. Will this be ok?
