So this is the response from HW
So looks like my Bike a 2010 Ultra CVO will not utilize either one if these products.
Might be easier just replacing the stereo completely.
Hi Greg,
You will not need either of those parts. You already have the WHK35 on your radio and the WBP16 is only for 2 channel amplifiers.
Here is what we tell people about removing the stock amplifier on the bike.
The best, cleanest thing to do is also the most work; remove the factory amplifier and it's entire harness from front to rear. If you'd rather not go that far though (and we wouldn't blame you), then at the very least you need to disconnect the entire harness from the bike completely.
Keep in mind that the stock amplifier harness uses T style connections to effectively "interrupt" the regular radio harness connections. When disconnecting the amplifier harness, you need to put any of the left over radio harness connections back together.
Rear Pods
Inside each pod you'll see 2 sets of wires coming in, one set from the regular radio harness, and one set from the amplifier harness. Disconnect the amplifier harness connectors, and re-connect the 2 left-over radio connectors back together. This reconnects the speaker pod wires to the rear outputs of the radio.
Under the Tour Pak
Here you need to disconnect the amplifier and harness connectors completely.
Under the Seat
Here you need to disconnect the power and ground connections to the amplifier harness.
Under the Fairing
Disconnect all of the connectors on the amplifier harness, and again re-connect the left-over connectors that were on either side of a T style connection. Be sure to disconnect the extra speaker wires piggy-backed on the front speakers too.
When you're all done, the amplifier harness will just be dead weight, which is why most people remove it and the amplifier completely. If you have the Tour Pak, seat, and front fairing apart, it shouldn't be too difficult to get out of there at this point. But leaving it on the bike won't hurt anything either, just be sure to secure all loose connectors when you're done to keep them from making noises and causing problems in the future.
Hope this helps,
Rich
