Front and Rear 8" Rings That Pair Into Quads
The front rings sit up front and accept either a midbass or a subwoofer. The rear rings use the same 8.625" outer diameter, 7.125" mounting diameter and ½" set back, and they pair with the front set.
If two 8" speakers are not enough, add the matching set. The front and rear pieces match up, so the saddlebags do not need to be redone to reach a quad layout.
Installation Notes
- Holes must be predrilled before using screws. Do not use self-tapping screws.
- A two-part epoxy is recommended but not required to bond the adapter to the saddlebag; the listing gives 3M 08115 as an example.
- Some bodywork knowledge is expected because the saddlebag has to be cut.
- These adapters were CNC-machined from stock bags. Depending on the bag, small modifications may be needed, such as sanding the mounting face of the adapter or filling small gaps with silicone caulk. A quality aftermarket or stock bag gives the easiest result.
- These are custom-made parts and all sales are final.

What do I need to know before installing?
Predrill the holes before using screws and do not use self-tapping screws. A two-part epoxy such as 3M 08115 is recommended but not required, and you will be cutting the saddlebag.
