JL 1000/1 problems...
 

recently my JL was starting to have some weird problems that i don't know what it could be. first off it gets super quiet after pumping it on a short cruise after like 20min. then i noticed the other day it gets really hot and puts on the thermal light after playing maybe 4-5 songs. before i took it out it was also cutting out (getting really quiet) and almost sounding like it was reversing polarity on hard bass hits. it just doesn't seem to hit hard AT ALL anymore. i metered last year 140.7 on TL and this year i hit 134.4
