Make sure rca cables are tight at the amp and head unit, if you didn't put the sub in the box yourself or buy a retailer.. check the connections yourself. if it's an old amp it may be burnt up. some head units these days require you to turn the sub on (especialy alpine) really need more info on what you got and how old it is.
I repair car amps for a living. Been doing it for 17 year and have an electronicics engeer degree. Sounds like the outputs are shorted. If it comes on the it's not a power supply problem but if it goes into protech mode it could be a few things. Leyt me know if you want my help. I get amps shipped to me from this site all the time. I am the cheapest amp repair in the USA. I don't charge a bench charge and most prices are $60-$80 plus shipping. Sometime lower depending on the problem. I offer a 90 warranty also.
