2014 - Present Harley 5x7 to 6x9 CVO Lid Adapter Kit

Notice: This article is to assist in your aftermarket horn tweeter installation for maximum performance; however, this kit will also work without an aftermarket horn tweeter.

2014 - Present Lid Kit w/ HXM69F4
  • CVO electronic lid lock mechanisms are compatible with this kit, with or without the addition of our optional CVO lid lock adapter.

Step 1:

Place your lid on a level non-scratch surface. Unscrew and remove the grill. Tape off the entire painted surface of your speaker lids to protect them while you work. Remove lid hardware and latching mechanism.


Step 2:

Cut the plastic basket off of the under side of the lid with a oscillating multi-tool followed by a grinder. You'll want a flat mounting surface for the kit to bolt up to. Be very careful of the painted surface of the lid. It is easy to damage. Do Not grind off the four factory speaker grill mounting points!!!

Step 3:

Use small cutters to remove the last pieces of the basket where a grinder will not reach.
Cut off last of the basket with snippers

Step 4:

Enlarge the factory 5x7" speaker mounting holes with a 17/64" drill bit. Insert the supplied aluminum nutserts from the top side of the lid and squeeze each with a proper nutsert tool. These are not pop rivets, so Do Not over squeeze!!!

Note: Once complete, re-install the grill and latching mechanism using your pre-existing hardware.

Step 5:

Your kit comes with a generous amount of quality foam speaker gasket. Install the gasket on the lid AND between the speaker and the adapter. It is critical to performance of the speaker system that the speaker have an air tight seal against the bag lid.

Step 6:

On a smooth surface, place the M075T over the pre-marked screw points on the bracket with the Diamond Audio emblem pointed towards the large opening. Hand tighten securely with our provided (four) black stainless steel 1/2" phillips panhead screws. Do Not overtighten!!!


Press the pre-wired tweeter harness into the channel by hand. The harness should appear similar to the image below when installed correctly.

Recommendation: Attach a small black zip tie securely around the vertical channel and cut off the excess with small snippers. Do Not cut the harness!!!

Step 7:

With the threaded inserts and foam gasket securely in place, its time to test fit the bracket. Notice that one of the mounting holes has a open slot. This will be the rear outside mounting point, the opposite side of the lid latch. Once you have completed test fitment, place the speaker bracket over the protruding nutserts and gently press to into position.

Step 8:

Place the adapter over the bracket. Make sure the open slot of the adapter is directly above the open slot of the bracket, on the outer edge of the lid, opposite side of the latch. Place the provided (four) 2" phillips flat head machine screws in their associated fastener holes and hand tighten each screw with a screwdriver. Note: The nutserts are aluminum and the machine screws are stainless steel. Dissimilar metals can create galling between sliding surfaces. Hand tighten only!!! Do Not overtighten!!!

Step 9:

Screw your new Velocity R690 6x9" speaker into place using the supplied (four) #8 1" phillips stainless screws to run through the entire thickness of the adapter for maximum strength.
