Well, here it goes. About 3.5 months ago, i bought a directed 350d amp from ikesound. It was a refurb. I bought it for my girlfriend, and i just got around to installing it this past weekend. Only problem is, after i hooked it up, the amp powered up, but had no output. I pulled off the back panel of the amp, and it doesnt appear to me that anything "blew" internally. There is no black spots anyway, but i dont really know what im looking for. Is there anyone that might be able to diagnose this problem for me with this info? If you need to know anything else just ask. Thanks guys.
