I want to add an Aftermarket Sub to my new HHR. I do not have the factory piece with a sub vent (I am guessing that is what it is called..). I can go to the factory and buy a new one, but I am sure it is gonna cost an arm and a leg. Anyone know of a cheaper place??

I want to stick with the factory look.

 

I purchased my factory sub box off of Ebay. GM parts direct list them for sale, however they have been discontinued and are out of stock.
