## Description

Product Description Boss CAP8 8 Farad CapacitorFeatures A capacitor is a passive (it consumes, but does not produce, energy) two-terminal electrical component. In building a sound system for your car, you would want to use a capacitor for a couple of different reasons. The main reason a capacitor is always recommended is for power reserve. The capacitor stores energy and releases it very quickly to the amplifier(s). Music is dynamic, no matter what type you listen to, and the dynamics can vary quickly, going from soft voices to thundering bass notes. These moments are where the benefit of having a capacitor is heard. The amplifier requires a constant amount of steady power to function efficiently and power the speakers. A capacitor will keep the power going to the amplifier consistent and stabilized, which means a better-sounding system. 4 FARAD Capacitor with digital voltage display, Chrome finish, Brand New capacitor, Full Manufacturer's Warranty, Finish Colour: Chrome, Equivalent Series Resistance (ESR): 0.00195 Ohms @ 120 Hz @ 25 Degrees C, Low-Level Input Voltage: 20 Volts Box Contains 1 X Farad Capacitor

## Questions & Answers

**Q: what all comes with it?**
A: Hello, The CAP8 comes with a 1 Watt/51 ohm Resistor and mounting hardware.

**Q: Does this model flash to the beat?**
A: Hello,
The CAP8 only flashes when it is charging.
Thank you,
Boss Audio

**Q: Does this come with a distribution block and can it power a 4500w amp?**
A: The distribution block is built in. It has a in and a out for the positive and negative.  While the capacitor will help the battery and alternator supply enough power to turn it on it may not be able to supply enough support for those really low tones constantly.  I would recommend running a dual battery setup and if there is enough space to do so upgrade the alternator to as high a amperage as you can get. In my case I am driving a 1980 f350 and I upgraded to a 150 amp alternator and all lighting is led. I also run 2 batteries and am looking at installing a second alternator to supply enough power for my amplifier setup. I am pulling 3500 watts. When you install a larger alternator like I did using a 1 wire alternator you will also have to run a significantly larger wire from the alternator to the battery.

**Q: I have an 4000 watts hifonics amp and i have re audio sx 18 d2 1000 watts do u guys think this capacitor gonna handle my system?**
A: I think 3.5 farad its ok
