Bought some car audio stuff... no idea what it is
 

Hi, I would like to preface my post with: I know nothing about competition car audio, so please be patient and kind if I use the wrong terminology etc and please explain things to me like I'm 5 years old. Thank you.

I recently purchased the contents of an abandoned storage unit and I've come here looking for some more information on some of the items I know absolutely nothing about.
There are three subwoofer speakers in wood boxes. Two 12" Rockford Fosgate Punch P2 and a 12" Infinity. Those I can research a lot easier than the next item, but by all means give me the low-down on those as well.
The next item took me days to identify and it is what has brought me to this particular forum. It's a competition series capacitor, but I can't find the brand *anywhere* online. On the cylinder it says:
Chronic
New trend in the car audio industry
Competition series
20 DCV 95 C
1,000,000 µ Farad (MFD)
ESR ≤ 0.00198 Ω
Max 20 VCD Surge 24 VDC
Work temp -25to 95C

And here's pix: http://pho.to/AbKfY

Who made it?
Can the actual farad be determined from the info on it?
I drive a 20 year old Hyundai Excel hatchback , this stuff would literally fill the entire back of my car, so understandably don't want it, so now what?
Value?

Thank you very much!
