Review: Overkill but good anyway. - This guy is awesome. I got this thing and it is a bit overkill for what I’m using it for, but it does its job well. I used to have voltage drops low enough to literally bog my amplifier at kick drums. Nothing dims. It has an automatic turn off, so you don’t need to wire another remote wire. The size is a little big, but it’s a 2.5 farad so I’m not surprised. It gives out a fair bit of juice. I like it. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07B7B3LGJ | | Best Sellers Rank | #1 in Car Amplifier Capacitors | | Customer Reviews | 4.3 4.3 out of 5 stars (2,469) | | Date First Available | March 5, 2018 | | Is Discontinued By Manufacturer | No | | Item Weight | 2.14 pounds | | Item model number | SCAP2D | | Manufacturer | SoundBox | | Manufacturer Part Number | SCAP2D | | Mounting Type | Pole Mount or Snap-In Mount | | Package Dimensions | 9.41 x 7.91 x 3.98 inches | | UPC | 859256005907 | | Upper Temperature Rating | 85 Degrees Celsius | ## Product Details - **Brand:** SoundBox - **Capacitance:** 2.5 Farad - **Material:** Aluminum - **Maximum Voltage:** 2.5 Volts - **Shape:** Rectangular ## Images ![SoundBox SCAP2D, 2.5 Farad Digital Capacitor for Car Audio - 2500 Watts - Image 1](https://m.media-amazon.com/images/I/51tZzy3xw2L.jpg) ## Questions & Answers **Q: I have pioneer a1686r 350w & a6996r 650w speakers, joying front unit, also want to buy a subwoofer and amp. should i get one of these caps?** A: You should always back up you amps with a cap it stabilizes and protects all of you cars electronics and improves quality of audio **Q: There's an audible alert for something since this cap has a buzzer in it's circuitry. anybody know why? says "notification safety sound alert" in desc** A: Yes, it’s for when the voltage contained in the cap goes under 10 if I am not mistaken. **Q: how hot does this thing get?** A: Am running 1000 watts in my Subaru I don’t feel it hot at all! **Q: can 2 be connected in parallel to get greater output?** A: Just buy a 5 farad of the same brand for $46.
