Re: Stereo Capacitor

A capacitor will help your electrical system supply your amp with a smoother source of energy and that's the bottom line. They DO work. 90% of it is how it is installed. Proper gauge wire is a given, you can't go too big. The cap needs to be installed as close to the amp as possible, less than 1 foot of wire between cap and amp is ideal. A low resistance battery (spiral cell) works almost as well as a cap but must be installed as close to the amp as possible to be effective. The cap will react to changes in voltage quicker but the battery is obviously a larger supply of energy. Of course all that energy comes from somewhere so you need an alternator to supply that battery and cap with enough energy to stay charged and reduce extreme voltage drop. Every aspect of the system, alternator post to amp set screw is important we're only talking about 12 - 14 volts here guys it doesn't take much resistance to screw it up.
What he said!
I have used caps on all my builds... the best one I have used is the
Alumapro 15 farad call "The C.A.P." I used to use three batterys in my biggest competition build. I got rid of two of them and used the big cap. I also used a 200amp alternator with a variable regulator that could be set from 10 to 15 volts. I set mine at 14.2 volts which was just under the max allow by IASCA at 14.4. Any thing over 14.4 was a DQ. I run this variable adjustable regulators on my Tys and keep the voltage at a steady 14 volts. I helps the fuel pump, injectors, etc as well as all the electronics when the voltage is high andd steady. Our fuel pumps put out a higher steady volume at 14 volts the 12.8. An unsteady or low voltage plays havoc on our tuning.
Don't do the yellow tops. We sold tons of yellow tops when I had my stereo store. The problem is that although they have a better reserve and a better deep cycle life, the warranty was only for a year vs the red tops at seven years. Unless you are going to sit and run your stereo for long periods while your truck is not charging, you don't need a deep cycle. Also, you should not be running your stereo components at the low voltage ranges anyway as it's hard on them. We used the yellow tops in competition, because we had a part of our judging with the cars not running, thus as the batteries drained, the yellow tops could be "Hot" charged back faster from a low voltage. If you did that to the red tops, they couldn't take the hot charge and cook themselves.
Deep cycle recharging is even hard on deep cycle batteries, thus the short warranty period. Buy the red tops. Keep them charged and enjoy a long term warranty.
For all of us that leave our trucks set for long periods of time. Put a trickle charger on your batteries and kep them up. A good way to weaken and/or kill a battery is to let it discharge and then quick charge it. A slow charge is the best way to bring a battery back from a low voltage, discharged. Putting on a set of jumpers to start your truck and letting your alternator recharge is an emergency only solution, as even small amp alternators are putting out a high enough amp "hot" charge thats hurts a discharged battery.
