hello..

recently i've installed a pre-amp on my 91accord sedan..i've hooked up everything nicely and all.when the key is at ON,the radio works fine as well as the amp.but when i start the car,the clock and the radio's dead plus the hazard light came up without blinking with the 'ting tong' sound.all the meters went crazy.checked the 7.5A fuse,it doesnt break.took out the amp and its still there..does anybody have any idea why this happen and how to overcome this..i've been looking throughout the weekend and could fine nothing..

 

did some checking this morning and found out that the grounding point (those with white covers) were loose..tighten those thing up and everything's good..

 

Excellent! Welcome new member, even though you figured it out yourself...
