I've had this amp for a while now and never got it fixed. It's Lanzar Vibe 240 and one night the wires got crossed and I think it went bye bye. I bridged the amp for a 4 ohm load and it makes speakers go in and out, like a it's playing DC current. The left channel does the same thing. The right channel, however, makes a speaker go really fast, like playing a sine note but I can't tell what frequency. Any idea what happened to my amp and how I can get it repaired?
