have successfully wrecked up my jbl amp after 4 years of faithful service!!! left the boot open for half an hour by accident , rain fell and i thought sh=t!!
didnt start it up at all but took it inside and dried it out for about a week , put it back in the other day not expecting miracles , but it still works but only when the engine is off otherwise there is massive interference!!! its so sensitive to eletrics now that the aerial sounds like a tank and i can use the brake pedal as a drum !!!!!!!!
any ideas at how i can stop it being so sensitive ?? cheers
