I just hooked up another PSU with thicker 12v cables and it didnt do it again..... i guess it is the PSU then i will try in a car in a couple of days to be sure

I need a multimeter for to know that right? The problem is i dont have one :/

Hi guys so im new to this forum and i have a question, I got a old Caliber CA 505N amp and i connected it to a 450w PSU (the amp is 1050w) and when i connect my speakers or subwoofer it makes a weird noise when playing loud. The subwoofer makes a "knocking" noise and the speakers just crackle...
