Wiring Stereo Amps And Caps With Bus Bar

Setting up two amplifiers and a capacitor to power a DC bus bar distribution center. As opposed to wiring everything to the capacitor, this is a much safer and cleaner option. In addition, you will be able to expand your car audio system in the future.

Parts And Tools Used:

Why Use A Bus Bar

In most cases, when wiring up a bus bar, heavy gauge wire comes from the battery and lighter gauge wires are used to connect accessories. As a result, your accessories, in our case stereo amplifiers, will have the power they need to run effectively. Underpowering your accessories can shorten their life and who wants that.

Why Use A Capacitor

We wired our mono amplifier for our subwoofers with the same gauge as our battery supply cable. The additional power that the amp required was compensated for by wiring a capacitor to the bus bar. Additionally, capacitors extend the life of the battery since they minimize power spikes.

Never Connect Battery On Discharged Cap

Once the bus bar has been installed, do a final check to make sure everything is tight. In order not to blow a fuse, we disconnected the capacitor positive cable from the bus bar. We then connected the battery that was powering everything but the capacitor and made sure that everything worked.

How To Install A Capacitor On Your Amplifier And What Not To Do

How To Charge A Audio Capacitor Easy

Once we are sure there are no issues, we can now charge and connect our capacitor to the bus bar. To do this we used jumper cables connecting the positive cable to the battery. Using the other side of the positive jumper cable, we connected it to the positive wire on the capacitor. Sparks fly and the capacitor is charged. It can now be connected to the bus bar. Using this method is much faster than using a resistor, and you will not blow the inline fuse at the battery.

I was never a writer, constantly failing English in school, I felt that writing was not for me. Over 20 years later Danielle and I started a blog, weird right. Danielle loves to write and supports me in my own writing as she creates her own content on this blog. We got our start on YouTube "ChrisDoesWhat" to improve ourselves, we continue to help others. Then we expanded our YouTube Channel with this blog, it seemed like a logical next step. We continual are looking for ways to improve ourselves, who knows where the journey will take us, what our next steps will be. We met in Washington State at Fort Lewis Army base and got married 3 months later in 1997. We have traveled the world at first only because of the Army, later we traveled on our own cause we loved it. We have two adult size boys, one in the AirForce, the other in HighSchool and taking college classes.
