Engine is 4g64 2.4L, only available on the GS Spyders. Nothing is is individually for sale on my car, but I am looking to sell the entire thing.

And the sub is directly underneath the amp rack, hidden away. If you notice the size of the trunk opening, it's virtually impossible to display a dual amp rack AND 15" sub. Plus, I've found rattling is minimal in this position. Even if I was to remove the amp rack faceplate, it'd be difficult to get a shot of the sub because the area is so cramped...so you're just going to have to take my word on it.
