Phoenix digital 1.5 farad capacitor installation

I lost my installation instructions for this capacitor. I know I need to "charge" it before I install it and I have to use a bulb or something to do it. But how is it done, and once that is done how should it be connected to the amplifier.

Re: phoenix digital 1.5 farad capacitor installation

First off Charging the capacitor can put you holding a high power voltage source. This can be very dangerous. It is enough to kill you. I suggest for safety go ahead and mount the capacitor in its location. The easy way to charge a capacitor is using a 12 volt Battery Charger. Hook the charger up to the capacitor just like it is a battery. + to + and - to - ... Charge the capacitor until the charger meter falls to near zero amps or indictates full charge. No need to use a light bulb or anything. The Charger comes with it own limiting circuitry. I will be posting the wiring instruction shortly.

upgrade all 12v wires running to your system to 0 gauge to kill you wiring to small problem when dealing with systems bigger is better double check to see if you alternator is putting out enough power for everything just because it say it will doesn't mean it does upgrade your capacitor seems to be falling you because there made to store power when needed and also get your battery check for any defects and add and extra just for your system

Describe how to connect a scosche 500k micro farad

Put the capactior in parallel with your battery right before the amplifier. So Postive lead of cap to your 12 Volt line and negative lead goes to ground. It is also suggested that you charge the cap before placing it directly in parallel with the 12 volt rail. yo ucan do this by using a 1000 ohm resistor with a power rating of 1 watt. Disconnect your amplifiers so it is just your cap and battery. Replace the fuse with the 1000 ohm resistor. Once the resistor is in place hook up your cap. It will take a little bit for it to charge. RC time constant is T = Reistance X Capacitance. So 1000 ohms X .5 Farads = is about 8 minutes, or you can just measure the voltage with an volt meter and when the cap reads 12VDC you can then hook it up. BE CAREFUL NOT TO SHORT TERMINALS. THIS CAPACITOR I STORING A LOT OF CHARGE.

Hey i had 2 car amps +for 4 speakers(140W maxi) and a sub 12inch

1 cap, either .5, 1 or 1.5 farad will be fine. they make 5 10 and 20 farad that cost way more than u need to spend for 400 watts RMS. i like the rockford fosgates, you can get a low cost Tsunami, just make sure you follow the charging instructions.

Ive had the amp for a few months now pushing 2 12" solobaric kickers. I noticed this morning that it is making my lights dim when the bass hits. Im thinking i need a capacitor, but i dont know how big i...

Just get about a 1 farad capacitor. The only problem with this is, now your alternator will be under unwanted stress and will more than likely go bad ove time. With a stock alternator it is likely to not be made for that much power. The problem is, that now, it doesnt just have to keep the battery charged, but it also has to keep the capacitor charged.

I enhance volume car light shimmer and amp off.

Need more info. Are you sying that your lights pulse to the bass? Capacitors help. I would recomend at LEAST a 2 farad. Make sure you are using GOOD QUALITY 4 gauge power wire. So many "kits" say 4 gauge, but strip it back and you have a glorified 8 guage wire. I've seenit. Also, MAKE SURE that it is ran to the bayttery and use the SAME gauge for the ground (no more that 4 feet if possible).

In case your next question is "how do I hook up a Cap?", here it goes:

Power AND ground to the cap, then power AND ground from cap to the amp input. So very easy!!

Take care,

Rockford 1 farad capacitor

The 1 farad capacitor is something added to current hungry systems to help keep the supply voltage at the proper operating level.
If your amp does not work after putting one in your system, but it worked before you put it in, you most likely have it installed wrong.
The capacitor should be put in parallel with the main +B voltage of the amplifier. That means you would connect the positive side of the capacitor to the +B voltage supply of the amplifier and the negative side of the capacitor would go to the chassis ground.

If you have it connected in series, or inline with the +B voltage supply, the capacitor would be blocking the voltage to the amplifier.

Without more information on your problem that is the best answer I can give you.
If this does not help, please supply more information and I will be happy to help you further.

Wrong connection continuation

If you're installing this in a vehicle with a 12 volt charging system (most automobiles are 12v), I think the batteries may be dead in your multimeter. You shouldn't read anything over ~15v.

When you measure this again, place the black lead on the ground terminal of the amp.
