Capacitor hook up question., XTREME 1.25 FARAD Options

[Snyper94GT]

I purchased an XTREME 1.25 FARAD capacitor. Upon opening the package I noticed that the capacitor had a + and - connection point. Most smaller capacitors only had a + in and a + out that I'd seen (never seen one for a system before). The directions were a bit confusing. Here's how I hooked it up a positive (direct feed from battery) coming in to the positive and a ground going to the -. I then took a connection from my amp which was the + lead to my amp and hooked it to the + part of the capacitor. I let it charge the capacitor and then started up my car. Yet now my lights still dim as if it's not even getting a charge reserve from the capacitor. Any idea's on if the is right or not. Any help would be great thanks!

Yes I've read that you've said that the capacitor doesn't work. But I really don't understand why they wouldn't. Because don't they store a charge much like an alternate battery. Hence when the bass hits doesn't it suck from the capacitor's supply? Yes the alternator will still have to charge the capacitor up again. But it still shouldn't do it from the beginning to the end correct? Shouldn't the dimmin' at least be diminished at least a little while or for sometime until the capacitors charge is drawn out completely? You may be right but my understanding of capacitors doesn't seem like it should do it from first bass hit to last. Thanks!

Additionally my amps got 2 25 amp fuses.
