check the tightness of all power connections and grounds and possibly clean the terminals. Do your RCA's run along any power cables ? Also could be a bad connection behind the HU. Intermitten stereo issues are biaatch to track down so good luck !
just giving you a hard time, i just dont ever remember making a sharp turn at 25 unless a rider was in danger or to avoid a object...just thought it was funny thats all. sorry
