Hello Hog,
I attempted to access your website via your hyperlink and web address. Both came back without connecting to an active account? Are you still in business and selling these sub- brackets, I wish to purchase one? Thx
 
You have approximately 1-3/8 inches behind the amplifier mounting plate before running into the external body panel, but be careful to not use mounting bolts/screws that are too big for securing the amplifier.

We used a Kenwood KAC-8405 amplifier in this install. This is a 4-channel amplifier with a footprint of 11 inches x 9-1/2 inches. On the electrical side, we did a bridged setup to only run the sub woofer. Our head unit handles the door speakers just fine by itself. Position the amplifier and mount it as you see fit. We used the mounting hardware supplied with the amplifier from Kenwood.

The amplifier mounting plate allows for two major footprint sizes; 12 inches x 11-1/2 inches for a vertical mount or 13-1/2 inches x 8 inches for a horizontal mount. As a technical reference, we have identified amplifiers that fit this footprint (mono amps, 2-channel amps, 4-channel amps and 5-channel amps) on the Whole Hog web site. You can find the amplifier technical information at www.wholehogtech.com

After we secured the amplifier to the mounting plate, we again did a test fit to plan ahead for wiring. On the Whole Hog web site we discuss that the wiring and amplifier adjustments may not be accessible after the plate is secured, so keep that in mind during the install.

Do you still offer this?
 
There are threads showing other options, this is just one of many Subwoofer Options... - https://forum.ih8mud.com/threads/subwoofer-options.952649/. Some use existing powered enclosures and mount behind the panel and other go full custom and do a fiberglass molded unit. I used the factory bracket and found a woofer that fit. Albeit, the level of execution depends on how much of an audiophile you are. I was going for getting rid of the crackling from the rear and just have some additional depth to the sound.

Thank you for this!

Thank for saving us the search :cheers: baselining the LX burned the MUD search tab into my retinas :hillbilly:
 
An option that I think is a good balance between sound quality, cost and effort is a powered sub in the passenger rear quarter panel area. You can tap into the audio signal that is already there from the factory speaker and then run an appropriately sized power source for the sub. A relatively simple bracket can be made to securely mount the sub behind the factory panel without visible mods to the 80.

Going this route allows you to avoid trying to build an appropriately sized box to match the speaker/sub, available space, amp, etc. which is complicated work if you want to get it right. Most powered subs are pretty well designed and should give a balanced, tunable sound even if the power/output is moderate.

An added benefit is that you can run an extra large circuit to that quarter and then add DC connections for refrigeration, etc. while you are installing the sub.

There are different subs that can work in this location but the sub that I installed is this one: Cerwin-vega Mobile VPAS10 Powered Active Subwoofer Enclosure

You can see the bracket, plans for making the bracket and photos of powered subs installed here:
