So I buy this in December. Works great for about 7 trips out. Last week I take everyone out and none of the line level speakers work. The sub still works off the pre-outs. Any ideas? I called crutchfield and they said to unhook all of the line level speakers, hook one known good speaker up and if it doesn't work the internal amp is probably bad. I did that and the one speaker doesn't work. I was hopeing there was an internal fuse or something. The few things that bother me are the 4-6 week lead time on getting it repaired, and that if it died after 7 trips, who is to say it won't die after the next 7. Anyone know what might have caused this, or if there is anything I can look at with this unit? I am an electronics technician by trade, but I don't work on car stereo's.
