What do capacitors do for subs

I installed the equipment in my truck tonight and it sounds great. My lights dim a little when I have the gain on the amp up and the subwoofer level up on my head unit but it's not too bad. I might look into a higher output alternator. Thanks again you guys. It is to adjust the senstivity of the amp to allow for the voltage of the signal coming into it from the HU. Your HU has 4v signal strength so your gain should be somewhere in the v range.

Anything further clockwise on the sensitivy dial and you're just increasing the likelyhood of damaging your equipment while getting no benifit in SQ or SPL. Also - for best results it's best to use little if any bass boost, LPF in the range, and ISF at 25 if your enclosure is ported, 15 or off if it's sealed.

A simple way to see this is to look on an oscilloscope at an AC to DC rectifier and the effect a cap has on the output.

You got five batteries…. What I would like to see is a non-biased technical article that compares car audio capacitors to real capacitors. Sure you can hop on Crutchfield and buy a 1. I get the impression car audio capacitors are just big, slow, general purpose caps.

I want to see if anything can be gained by using proper capacitors. Pete- no, alternators are only part of the solution. For best charging, higher output or more alternators should feed into batteries. This is your best option for solid electrical with minimal drain on amp power.

I have a Farad capacitor bank that charges up to 84 volts. Great explanation. The difference is using ultra capacitors instead of regular capacitors.

Think of an ultra capacitor as a battery super enhancer. Will be getting a F to improve performance and audio too. Quick Navigation Capacitors: What they are and are not. Power caps are built to store and discharge power quickly. In car audio applications, this particular ability is utilized to provide on-demand power to various components of the audio system, especially the amplifier.

Apart from application in car audio systems, capacitors have varying uses in other types of electronics. In fact, almost any electronic device contains capacitors — from small portable music devices that use small caps to heart defibrillators and lasers that use very big caps.

The key reason for including caps in an electric system is their ability to provide a great deal of power in very short periods. Capacitors and batteries perform a similar function of energy storage and discharge. However, they differ in several ways, in design and in function. A capacitor stores potential energy in an electric field while a battery stores energy in chemical form.

While the technology for chemical storage allows batteries to have greater energy density, latency in the process of converting chemical energy to electrical energy makes the process of energy discharge slower in batteries compared to capacitors. Also, capacitors have low internal resistance than batteries. These reasons explain why a cap can deliver large amounts of current very quickly, something that a battery cannot do. Depending on the music being played, the amp s may need short energy bursts especially during transient peaks.

An attempt to draw this current directly from the electrical system may cause a significant drop in voltage — commonly known as voltage sag. This sag is dependent on the resistance of the wire connecting the power source battery and the amp. Adding a capacitor can help to solve his issue. Here are some precautions drivers and passengers can take to avoid being injured by airbag deployment.
