The speakers in the car are ,well kak, tbh. One has blown and the others are standard with a poor sound. Does anyone know of speakers that will just fit in the standard rear and door positions?

They don't need to amplify Guns N Rose across Wembley stadium, but a good sound quality is what I am after. 

Or if not, what size speakers are requires?

 

Cheers

Found some and ordered 🙌
