It reads when I first start the car but a minute later it shuts off, it is full I believe but no display** A: They usually do that every now and then but it’s actually working. As long as the display never completely shuts off it should be good to bump **Q: Does it come with speaker wire?** A: Yes it does **Q: If I have a Capacitor do I need a second battery** A: No, the capacitor is connected in parallel with the battery close to the amp. The kit has very good instructions, fairly easy installation. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Don’t shock your self🤣 *by J***S on August 12, 2026* I love it so fab ### ⭐⭐⭐⭐⭐ Cap works ! *by C***Y on May 27, 2026* Solid no issues! And my amp and subs never cut off. I always get a strong current and strong bass! ### ⭐⭐⭐⭐ Things to know *by C***J on November 22, 2025* Firstly, Mine was professionally installed by the company that i got my system from a number of years ago, i was finally able to install it a few days ago. They used what came in the box, nothing else had to be purchased, in my case anyway, so this having everything you need MIGHT vary here and there. Though i did buy a current generation fuse holder to replace the older one, but that was my choice as it was nearing 10 years. Kind of amazing how small the fuses are now while having the same rating of its larger counterpart. Secondly, maybe its a given, i dont know, but so people are aware, the Cap only Turns On at a certain Voltage threshold, so there does have to be a certain amount of power draw on the Battery for the Cap to kick in. Which i was under the impression that if the Head unit was turned on and thus communicating with the Amp the Cap would always be On as long as the Head unit was, which does not appear to be the case. So for me, my Cap was correctly installed and does Work. If yours doesnt, you could have gotten a Dud, sure. But its also possible you didnt install it correctly. A Disconnect Switch would probably be a good thing to add as the Cap still gets the battery voltage even in its Idle/Off mode. 1 Final thing of note, the Blue LED is Very Bright so depending on the direction its pointed at you may need to cover it So far its doing what its supposed to, only time will tell if i remove it or keep it. Edit: The 4 AWG Wire it comes with is CCA and VERY hair like Thin, while it does do the job the strands are practically brittle. Get higher quality cables and youll be good to go. ## Frequently Bought Together - SoundBox 4 Gauge Amp Kit Amplifier Install Wiring & 2.5 Farad Digital Capacitor, 2300W Peak - Kicker 46KISLOC2 K-Series Stereo Line-Output Converter w/Remote Turn-On Output - Skar Audio RP-1200.1D Monoblock Class D MOSFET Amplifier with Remote Subwoofer Level Control, 1200W --- ## 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.gr/products/66223140-soundbox-4-gauge-amp-kit-amplifier-install-wiring-and-2](https://www.desertcart.gr/products/66223140-soundbox-4-gauge-amp-kit-amplifier-install-wiring-and-2) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-11-15*
