Got my system installed this week. There IS room beside the spare for this big amp. So, I was able to install a stealthbox and the amp and keep my spare. I'll try to post pics later today.

 

D'oh! I'll be interested to see the pic's so I can really curse myself!

 

I also can't wait to see this so I can free up the well for the stealthbox.

 

I finally took some pictures, but now I can't get into my photo album for some reason. I'll try again later.

 

As promised, here are some pics.
Nice install of the SWI-X
Amp in position
Amp lowered to get to controls. Don't have to do this much as I can set my crossovers on the HU

 

Very interesting setup I may have to give it a try. Thanks for the pictures.

 

In hindsight, I think a cleaner set-up would have been to remove the spare tire cover and have the amp mounting board extend to the other trunk hinge. I may still do that.

 

Ah I see now! I thought you had managed to get the 500/5 mounted above the gas tank behind the left hand trim panel. It looks good though!

That carpet you've used to cover the amp rack looks a damn fine match to the OEM lining
