Could I build my own amp capacitor with 6 of these
http://www.ebay.com/itm/281173041415
I saw a guy on youtube use 6 of these wired in series as a car battery. He took out his car battery and replaced it with these and even after sitting 3 days, they still started his car without hesitation so I figure that they would make a pretty powerful addition to a system.

What's an "amp capacitor"?
Super Caps don't do well as PSU filter caps. They're meant to replace batteries
in some applications.
The forum software is corrupting eBay links. I'll fix it.hmm, I just wonder what they have put inside that big can 
must be something real heavy to make people think its worth emptying their already half empty pockets

As far as I know, these super caps have a fairly high impedance at audio frequencies. So they may do alright for bass, but they would not help any above that.
Putting them in series will increase that impedance, of course.
Who knows? They might do well in parallel with more normal caps, especially with bass heavy music. It's worth try - tho it won't be cheap.

Those types have been around since the 1980s, at least. Very high output impedance. They are generally use to keep volatile memory alive, like station presets in a radio tuner.
Well if they are powerful enough to turn over a starting motor, the impedance can't be that bad I wouldn't think. would I just be better off getting something like in that second eBay link? I already have a 500k farad cap in my trunk but it's not enough since I upgraded my system. I'm pulling 1000 watts rms plus my cap is pretty old and I think it's fried
