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!

I'm not saying they don't work. I'm saying they just hide the problem. One case where they can make things worse is long bass tones. Like bass cd's. The cap will discharge and because the bass is still rolling now the amp and cap are pulling power putting one hell of a load on the alternator.

As far as your car the cap should make the lights stop dimming. Does your cap have a remote lead?
