yes i have 2002 tl type s with the factory 6cd bose radio with 2 10 sony xplod subs and a 1000 watt sony xplod amp i notice that after maybe a good20-30 min drive my subs fade out off and on do you think it's the amp maybe overheating or the radio not being able to push the subs i've been told that getting an aftermarket radio is much better for subs any input would be appreciated thanks
