It's 4-month-old din 66 Yokohama battery and currently testing Audio
System Twister F240. Prior to the amp installation, I never have any
electrical problem on my citroen evasion...
FOr those who want to repair amps.. call this guy.
Also for the Cirtoren.. probably the wiring is nto correct.. disconenct all speaker n rcas with the power wires in and see if it still happens... go back to the shop and get them to check,
