ive got a 1990 ford 150 reg cab i just bought 2 12'' kenwood 3012's and im going to buy the 9140d amp i believe it is its made by kenwood i was wandering do i need to upgrade my ground wire if so where is it and how do i go about doing this help greatly appreciated ready to start thumping im going to get a 2 farad cap btw

 

dont waste ur money on the cap..... since the truck is a little bit older u prolly should do new grounds. dont know where they are at on that. just look u will find

 

ight if anyone know where the grounds are hit me up that will be a major helper would it tell me in a repair manual

 

reallt its just batt- to chassis, find the engine to frame ground. get under there and find the cab to frame ground, its prolly rotted out by now it should be on top of the cab mounts to frame in corners

 

ok ill try to do that i think thats a perty easy job

 

yup
