very good on Mazda 2/Demio DJ/DL, the wire quality is not bad, no thin wires, only the length could be improved by a few cm and it would be 5 star because they fit more models. and as such is a little too short for my front speaker. for the rear they fit better because less length is needed.
perfect for keeping original connectors and wires intact but the wires should be a few cm longer.
