Printer Friendly Forum Posts - Any ideas what this might be?

Hi folks!

I'm currently in the process of planning the install of my new stereo and I have a question.
My car is a 2000 Lincoln Continental which has the factory 'premium' Alpine sound system (w/ 6CD changer in the console). Aside from the speakers in the front and rear doors, it has speakers in the rear deck and what sounds like possibly a small powered sub.
When I was looking in my trunk to figure out the amount of available space and noticed there's a fairly sizable box-shaped protrusion in the carpeting right below the rear deck, as shown in this picture (pardon the 'saggy' look - the pieces of velcro that are supposed to keep up the carpeting in the middle have separated from the carpeting, causing the 'saggy' look):

Upon closer inspection (and after removing the carpeting) it appears to be a set of two small, powered devices, but I'm not entirely sure what they are. They are seen in this picture:

it appears this plastic 'box' houses what could possibly be the amp to the 'premium' sound system? I'm just not sure. It seems the wires for the speakers in the rear deck run to this contraption.
The reason I'm wondering about this is because if it's the amp, I can get rid of this contraption and it would mean more free space for a new sub enclosure.

Anyone have any ideas as to what this box is? There's no lettering or anything on it as far as I can tell, so any info would be much appreciated!

Oh, by the way, the system that's going into this car - an Alpine CDA-9855 head unit, two Soundstream SST5.2 (5.25") speakers for the front, two Soundstream SST5.7 (5x7/6x8") speakers in the rear doors, a Soundstream T4-10 10" sub (in a ported enclosure), a Soundstream XTA720.4 4-channel amp for the speakers, and a Soundstream PCA1000D amp for the sub.

Thanks!
