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 Review: Read instructions - Good Review: Excellent ! - Alimente 1 ampli 1x1500W rms, frôlant les 100A, et un plus petit 4x50W rms de 50A sans problème... ## Features - 2000W Stabilizing Amplifier Flow Capacity - Nickel Plated Rust Resisting Post Connectors - Voltage: 16V Maximum / 20V Surge ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001DXAVTS | | Best Sellers Rank | 89,014 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 665 in Capacitors | | Brand | BOSS Audio Systems | | Capacitance | 8 Farad | | Capacitance Tolerance | 10 | | Capacitance tolerance | 10 | | Customer Reviews | 4.4 out of 5 stars 1,238 Reviews | | Global Trade Identification Number | 00791489108973 | | Included Components | Capacitor | | Item Dimensions W x H | 5.1W x 15.2H centimetres | | Item Shape | Rectangular | | Item Type Name | BOSS Audio Systems CAP8 Car Capacitor - 8 Farad, Energy Storage, Enhanced Bass From Stereo, Warning Reverse Polarity Tone, Voltage Overload Low Battery Voltage Led | | Item Weight | 1.68 kg | | Manufacturer | Boss Audio | | Manufacturer Part Number | CAP8 | | Material | Nickel | | Maximum Voltage | 20 Volts | | Model Number | CAP8 | | Mounting Type | Rack Mount | | Operating Voltage | 24 Volts (DC) | | Operating voltage | 24 Volts (DC) | | Shape | Rectangular | | UPC | 070992472758 791489108973 115970703926 880959961375 189326618691 999992669855 151903146163 100010956509 088020618207 100177400228 168141264320 806293548683 | | Unit Count | 1.0 count | | Upper Temperature Rating | 25 Degrees Celsius | ## Product Details - **Brand:** BOSS Audio Systems - **Capacitance:** 8 Farad - **Material:** Nickel - **Operating voltage:** 24 Volts (DC) - **Shape:** Rectangular ## Images ![Boss Audio 8 Farad Capacitor - Image 1](https://m.media-amazon.com/images/I/81cSBwBMSJL.jpg) ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Read instructions *by D***R on 18 October 2025* Good ### ⭐⭐⭐⭐⭐ Excellent ! *by M***M on 17 August 2021* Alimente 1 ampli 1x1500W rms, frôlant les 100A, et un plus petit 4x50W rms de 50A sans problème... ### ⭐⭐⭐⭐⭐ Good *by R***E on 20 July 2025* Good ## Frequently Bought Together - BOSS Audio Systems CAP8 Car Capacitor - 8 Farad, Energy Storage, Enhanced Bass From Stereo, Warning Reverse Polarity Tone, Voltage Overload Low Battery Voltage Led - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing - Joinfworld 12V Power Distribution Block Car Audio 2 Way Ground Distribution Block 0/2/4 Gauge in 4/8/10 Gauge Out 12 Volt Amp Distribution Block Splitter for Marine Automotive Car Boat --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/47869277-boss-audio-8-farad-capacitor](https://www.desertcart.co.th/products/47869277-boss-audio-8-farad-capacitor) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-29*
