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!

It sounds like you have it hooked up right. Positive to the cap, then a wire from positive on the cap to the amp's pos, ground both to the same point.
If the headlights are still dimming try getting a larger negative cable for the battery(along with 'better than stock' terminals) and/or double check the ground on the amp/cap.

I know everyone is gonna get sick of me saying this... but... capacitors don't fix the dimming light problem, they hide it. Your lights dim because the charging system can't keep up. In some cases the cap can make things worse. You need too beef up your charging system. To really fix the problem.

Here are a few things too check.

Make sure you have a good clean ground.
Check your battery cables for corrosion.

Also how big is the fuse in your amp. Our stock alternator is around 70 amps if your trying to pull much more than that a cap won't help.

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.

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?
