i recieved an audiobahn capacitor today and im not sure wich way to hook it up. one terminal has and positive sign on it and the other does not. which end goes to the amp and which goes to the battery? i tried both ways and only one seems to work, however, the audiobahn amp a18001d says lo in the led display. im not sure whats up, any help is appreciated, thanks

 

all the caps ive seen always had a + and - terminal on it, you would run the battey to the + on the cap, then from the + on the cap to the amp, then the other terminal was a ground. Looks good if you have/use the cap pass through terminals instead of ring terminals.

 

thanks for the reply, i hooked it up the way you said and it works great now. the only problem now is that it thumps when turning on and off the stereo. any reason for that?

 

I thought you had to charge a capacitor first???

 

charge it? how u do that? im sorry, been around stereos for some time now but never needed or wanted to install a cap. its the first time for me and the cap didnt come with instructions. i cant find instructions on the net either. thanks

 

some capacitors come with a little circut board with some wires comming off it. One is + the other - then just attatch it to the cap then you take the + and - wire from the board and apply 12v to the cap. Some have a red light on the circut board that will turn green or go off when it hits 12 or you can just hold a DMM to it and wait for it to get up the 12v then disconnect it. I read some where that the pop heard through systems is sometimes due to the order in which the stereo equipment shuts down, here is the explanation rockford gives,

When a car audio system utilizes additional components such as amplifiers and processors, those devices are turned on and off automatically with a signal from the source unit (known as remote turn-on).

Occasionally, those components may have built in delays that turn them on and off at different intervals. This is especially common when mixing different brands of components into a single system. These different turn on/off intervals may cause an audible "pop" or "thump" when turning the system on or off.

For example, if the amplifier in a system turns on before a crossover, the crossover may send a small transient signal to the amplifier. Because the amplifier is already on, it amplifies the transient signal causing the turn-on noise.

There are different methods to cure a turn-on noise, including devices that "delay" the turn-on of the amplifier until after the other components have come on and "settled down". These delay turn-on devices are available from most car audio accessory suppliers.

To cure a noise at turn-off, the amplifier must shut off before the other components in the system. To do this, you must delay the turn-off of the other components until after the amplifier shuts off.

This sounds like a lot of work to figure out, and it can be frustrating to get rid of such noises, but patience and a little "stick-to-it-iveness" will help you to find the source of your trouble and fix it. See your local Rockford Fosgate dealer for additional assistance if you run into trouble.
