how can i test a amp to make sure its working right? i have a friend who wants to sell me a amp for a deal i cant pass. but he doent know anything about car audio. he bought the car with the system in it and pulled the sub out because he dident like it. left the amp because he dident want to mess with the wires. whats my best bet to test it.
