2009 - Hummer - Speaker Mount Adapters
Instead of making your own adapters our of MDF or plastic, you can buy an engineered adapter that is guaranteed to fit and maintain the ideal positioning without modifying your speaker opening in the door or rear deck panel. Some vehicles have oval speakers and you will need to replace them with round speakers or components speakers and to do so requires adapters to convert them. We have a wide variety of speakers adapters for all of these reasons.
