having a dead short can be really hard on an amp and really lower its life alot of times they will burn out right away and sometimes a week later or so like yours might of. that shop didnt mess with any of your amp settings did they or do something so your amp would fail?
nope...they never touched it......i had my gains set high, but i think it had soemthign to do with the terminal touching for sure......i honstly don't know what happened that the terminal would melt..i mean i don't see how it'd get that hot in my trunk during the Minneota Wineter
