This will explain how to add a car audio capacitor for your mobile audio system.

Difficulty: Moderately Easy
Instructions

Things You'll Need:

  • Capacitor
  • Wire Cutters
  • Phillips Head Screw Driver
  1. Step 1

    Start by disonnecting your battery cables from the battery. Assuming you already have an amp and your other stereo components.

  2. Step 2

    Now you will want to mount your audio capacitor near your amp, its doesnt have to be extremly close, however, you will need to connect the two.

  3. Step 3

    You can now disconnect the power and ground from the amp, and connect them to the cap, if you have enough extra wire you can cut 2 short pieces to run back to the amp from the cap, or you may need to use some fresh wire.

  4. Step 4

    Once the cables are hooked to the cap on the input side, connect another power and ground from the output side, back over to the amp where you originally disconnected the cables from, once this is done, hook your battery terminals back up, and you are good to go! You 1, Cap 0!

Tips & Warnings
  • You can run caps in a series if you have powerful amps requiring more than 1 cap.
  • Make sure everything is mounted securely and safely

on 5/24/2009 Just to clarify a few points made, and questions asked.When installing a capacitor in your auto sound system, always ground each component to the frame, or body of the car. Never ever daisy chain equipment from one ground to the next and then connect the last unit to ground. Do always make sure that you connect the cap before the power in to the amp. If the AMP has an on board fuse, and did not come with an external fuse then adding a fuse before the power block may be a bad idea. Each component in a system needs to be fused separately; the "one big fuse before the power block to cover it all" scenario has lead to many fried component. Each part of the system draws different power amounts, or amperage and that�s why the manufacture supplies a fuse for that component. If you lump all the equipment to one power block, and put a big fuse before the power block, one of the componen...

on 5/18/2009 can you have a cap. inline BEFORE a FUSED power distribution block, then split from the block out to 3 seperate amps. i heard you shouldnt have a fuse AFTER the capacitor BEFORE the amp.

on 4/13/2009 is it possible to connect the ground from the output of the capacitor to the ground input on the amp?? or do you need to connect a separate ground for the amp

on 4/1/2009 hey i installed my system the same and ur actually good that way. The cap will supply the needed power to both amps. U could install a cap per amp afterwards but then u'd need 2 caps. I have 1 5f cap b4 my dual splitter and it works great.

on 3/30/2009 hi weird question but im running 2 amps, via a splitter, in other words power comes from the bat then into a 4 way splitter (im only using 2 ways)then to each ampcan i connect the cap before the splitter (so it looks after both amps) or do i have to have one cap for each lead (after the splitter)?
