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.

Have a Jl 500/1 installed Sat was slappin good puushin 10W6V2 high output box with rockford 1 farad cap. any way blew somethin smelled it amp still green no sound is only thing! sub still works checked on...


Check your stereo first. make sure the speaker outs still work if yes, the check your amp. If you know the signal is getting to the amp and not out to your subs, then your amp is blown. The high voltage transistors inside the amp usally are the ones that go out. Just open it up and if you smelled something, you can probably see it.

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.

Reconnecting two amplifiers adn farad capacitor


run a fused + wire from your battery to the + of the cap ground the - of the cap to a good grounding place on your car run a wire from the + of the cap into a one in two out disburtion block make sre it is a fesud one.then run one wire from each or the two out side of the dis block to each amp then ground both amps to a good ground.what type of amps do you have

I have been having trouble with my car stereo system


First reinspect your power and ground connections, vibration may have loosened them.

Then be sure that amp location has proper ventilation, (overheating will cause shout down)
A 2400 in a closed space will definitely need exhaust fans to help circulate cool air around the amp.

The cap should be mounted close to the amp and properly charged before use. It is connected in-line with the main power lead paying close attention to the power in and power out terminals.

Power in = from the battery
Power out = to the amp

Good luck

Is my alternator too small


If you're running the amp into a safe ohm load, it's likely that the amp is cutting out due to low voltage. You need to check the voltage with a multimeter connected directly across the terminals of the amp. If the voltage is dropping below ~10v, check the voltage across the main battery terminals. If the voltage is essentially the same at the amp and at the battery and it's dropping below ~10v, you need a larger alternator.

Amp clickin in and out


Had a similar problem, mine was a power problem.
Power meaning voltage.
Those big bass speakers draw lots of power. My original alternator couldn't keep up.

Question: Do your headlights dim in rhythm to the bass hits?

If so, your sound system wants more power than your vehicle is producing.

My first solution was a high output alternator. It worked great.

Then I added another amp. Not great anymore.

My second solution was to tie in a large capacitor to the amps power supply. (These a big (1 farad), about the size of a Pringles can)

Your amps power consumption is not uniform. Each time your amp punches the bass, it draws extra power. If that power isn't available, it starves and shuts down (if only for a second) then restarts.

The higher the gain, especially using a low pass filter, the more power needed for each thump. Thats why when you turn the bass down, you can get higher volume from the rest of the system.

How a capacitor can help (simply put):
In this application, the capacitor acts like an auxiliary battery, smoothing out power fluxuations. The capacitor builds up its charge literally between bass hits when power demand is low. Then releases it's charge when the demand is high. Think of it as an on-demand power boost.

Hope this helped

Rockford amp cut out


Disconnect all speaker wires from the speaker terminals of the amp and disconnect the RCAs. Replace the 30 amp fuse with a 15 amp fuse. If you turn it on and it blows the fuse, it's likely that it has shorted output transistors. If that's the case, you need to have the amp repaired.
