okay, so I got a used amp a while back and today I took it in to the shop down the street. first mistake. i asked if i could watch them bench test it since I was curious what equipment they used and also because I didn't trust them alone with something expensive of mine. we went into the back. the guy doing it was nice but he didn't seem like he knew much about this stuff. I asked him if he was going to use an oscilloscope or a multimeter and he just shook his head... after he finally got everything hooked up, he turned his head unit on and the low voltage light started to come on on the amp. then, the head unit just started to cut on and off. i almost wanted to get my amp back and run LOL. he then started turning the settings on the amp carelessly. all he did was power the amp up and powered a junk sub with it. i could have done that. when we got back in the office, he charged me $15. this will be the last time i come here.
i know it seems like i'm just ranting about this place but i'm just putting it out there to any other noobs like me. DO NOT take your stuff to some hole in the wall place. you paid good money for your stuff so do your research before you let anyone touch your stuff. i know i am farrrr from an expert but i thought i'd put it out there for anybody that's looking to get their stuff checked out.
