Adding classes to WooCommerce widgets

I am using several attribute filter widgets on my shop page. I would like to programmatically add unique classes to each of these widgets.

1. Is there a filter that I could use to do this?

2. If not, how would I do it? I heave already overridden another function as follows:

class Doublee_WC_Widget_Layered_Nav extends WC_Widget_Layered_Nav {

protected function layered_nav_list( $terms, $taxonomy, $query_type ) {
// My custom layered_nav_list function, works as intended
}

} 

I can see the widget classes are located in the WC_Widget_Layered_Nav class’s constructor:

public function __construct() {
	$this->widget_cssclass    = 'woocommerce widget_layered_nav woocommerce-widget-layered-nav';
	$this->widget_description = __( 'Display a list of attributes to filter products in your store.', 'woocommerce' );
	$this->widget_id          = 'woocommerce_layered_nav';
	$this->widget_name        = __( 'Filter Products by Attribute', 'woocommerce' );
	parent::__construct();
} 

I am new to object-oriented PHP and haven’t been able to work out how to override this. Simply duplicating the constructor in my custom class and changing the value of $this->widget_cssclass doesn’t have any effect (I’ll worry about making them unique later…I just need my custom class names to apply first!)

Any advice much appreciated!
