Remount the support struts over the speaker bracket using
the existing strut hardware to secure the speaker bracket

technician to make sure that the installation and operation of
this product will not interfere with or compromise the
operation or efficiency of any vehicle equipment! Before
returning the vehicle to active service, visually confirm the
