New member Username: Goldief550Post Number: 1 Registered: Jul-08 | I have recently had my stereo upgraded. I had a headunit, cap, amp and sub installed. I would like to clean up the installation. I am going to build an amp wrack and this requires me to disconnect the amp wires and cap wires. Are there any special precautions I need to take aside from obviously disconnecting the battery before I begin? Does the cap need to be discharged and or recharged before I begin? If so what is the best way for me to perform those tasks? Thanks |

They have (some) use but not enough IMO to warrant a purchase. To me a cap isn't even a bandaid but but a mask for a larger problem. Read this. A VERY good thread. https://www.ecoustics.com/electronics/forum/car-audio/452834.html |

Gold Member Username: Nd4spd18Northwest PA Post Number: 8007 Registered: Jul-06 | I don't know that I'd say a cap "draws power". What it does is the same as a battery, stores power. It just doesn't store enough to make any meaningful difference. If your lights dim a lot and voltage drops, either you alternator is not keeping the battery charged, or the battery cannot supply enough power fast enough, usually both. |

In a sense it's a battery charging a battery with the wires connecting everything applying more resistance. The biggest confusion I see with ppl starting out looking at caps is that they somehow believe they produce power. Only the alt does that. ANYTHING connected to a system is only adding to the alt's demand. Batts and caps are nothing but storage devices. If you don't produce what you use you're doomed eventually. , assuming you bump loud and long enough. |
