Capasitor

[Mattitjah]

Any one know? Any diagrams? I got a 2ch Amp and two subs. Do I need two capasitors? Where do I wire them in?

[bitcore]

depends on the wattage the amplifier consumes. The general rule is 0.1 farads per 100 W RMS the amplifier is rated for.
To install the cap, you charge it first, then you wire it in-line with the power cable to the amplifier.
It's best if you use one capaciter per amp instead of multiple ones per amp.
Caps come in different sizes. The more farads you have, the more power it's able to push out. If you have a 1,000W amp, you should get a 1 farad capacitor or larger.

I took this pic to show one member where the CD power unit comes from, but you can also see the cap wires in the background.

Basically, the cap has 2 prongs, a + and a -. You connect a ground to the - and run it to the same spot as your amp. On the + terminal, you connect two wires, one from the battery and another to the amp. You can see the red wire coming from the battery and the other red one going to the amp. You also want to mount it within 18 inches of the amp if at all possible.

OK, I have a hard time making heads or tails of your pic. but you explanation makes sence.
So, pos. from bat. to pos. terminal on cap, then on to pos. suply on amp. Neg. terminal on cap has common ground with amp. Correct? All within 18" of amp(why?).
And I only need one cap since I only got one amp.?

The negative terminal of the amp is supposed to be less than 18 inches because:
1. the longer the wire, the larger the voltage drop. Lower voltage means less power to the amplifier.
2. There is no reason not too. The ground can be to almost any metal thing in the car.

this is what it looks like on my car. its a rough diagram using MS paint.

[El Presidente]

Any install sheet Ive ever seen clearly states to install the ground at the same point as the amp.

As for that pic, the red wire under the speaker goes to my amp. If you look in the background you can see another red wire and gray wire. Those go to the battery and ground. Ignore the smaller pic in the large one, thats for the CD changer.

[El Presidente]

Mark, you have the cap's ground installed on the same line as the amp?

[Furious]

actually yeah it is, the shop said it will be ok and also beef up the ground to the amp or something like that. but i do know what your saying.
everything is in close proximity anyways so im not worried aobut distance.

Found THIS .
It's the same as what Furious posted.

(sorry)

[Furious]

no worries.

here is what you were looking at, yeah its similar to what i have set up
