My wife got me one of these for Christmas to add to my garage stereo, when it arrived from Sonic after less than a week I hooked it up in my living room just to see if it worked and it did but I didn't really test it out. Later that evening I went out to the garage and hooked this PBX 12.1 up to one of my receivers out there and it worked fine again, sounded ok but not as great as my Polk sub in the garage. Went in to eat dinner and after dinner I went back out to listen to it again, but this time it would not turn on and I discovered that the fuse was blown. Went to Lowe's and got some more fuses, well after many blown fuses I had to send this back to Sonic. Sonic Electronix gave me a full refund and I purchased another product.
