Amp problem - spud1973 - 04-05-2019
Hope someone can help I have got a kenwood amp and alpine sub now when the eninge is off it all works fine and dandy. But when the engine is started the sub starts thumping no music playing it just thumps on its own accord.
I have used a autoleads 750w power leads.
Now what I think I have done is earthed it out in the wrong place under one of the luggage strap loops.
Any ideas on a better earthing point please tell me
Thanks Pete

it needs to be earthed onto the chassis most people use the rear light fixings to do this

Those hook up points are on Chassis though?

oli is right matey any metal on the car as long as its not rubber mounted can be used as an earth....

It could be a bad earth somewhere else causing the problem, once you're happy that the wiring to the amp and stereo are spot on, if the problem persists then check out the engine ground straps and the other big wires (alternator, battery etc).

Thanx guys will check every earth im sure thats what it is when the tunes are playing it thumps hard. As I said it when there is no music and the head unit is on also if im driving and use the brakes or indicate it does it. Weird as all the systems ive wired into my other various cars have never done this.
