PCBLK2.0 2 Farad Car Capacitor, Energy Storage, Enhanced Bass

I am running a 4000 watt amp at 2 ohms with 2 12s. This capacitor is plenty of reserve power. No light dimming, no bass skipping, and my voltage gauge on my car does not move.

This 2 farad cap is probably the most awesome cap I've ever bought it was easy to install and the digital display is very clean and crisp and it does have a blue flashing light when you get the amplifier pounding. I have no static no problems the thing works great I would suggest it for who's ever installing an amp up to 2000 Watts

Now that I drained it and recharged it correctly this time, everything is working fine again. Original problem seems to be the "pro" installers never properly charged the cap using the little included resistor. Also, I'm pissed there's nowhere that describes what their errors mean or troubleshooting them. Previous Review: I can't find anywhere that explains what the different LED readouts mean! I emailed Planet Audio but no response. For 2 weeks it went blank, then it came back on but would beep every time I turned on my vehicle, then a month later it began acting normal for about a month, then it began to show an "e y" I believe it was.. now that went away and all it shows is an "e" (for error I assume) and the Blue LED light remains on. Previous Review: Used to beep every time I started my car, and it's blue LED bulb used to flash every time I turned up the music/bass really high. I'm unsure why both of those things stopped working AS WELL AS the digital voltage readout quit working. =/ (Side note: Don't forget to connect the remote wire like my "pro" installers had forgotten the first time around!!)

Bottom line- If you're driving down the road pushing 500 RMS watts without a capacitor on your system, you are running the risk of damaging your battery, and/or alternator, not to mention the damage to other on-board and computer components within your vehicle. After installing one of these on a simple Alpine 500W RMS amp driving a single 12' Alpine sub, I noticed an immediate improvement in not only the sound, but I also noticed that my headlights, tail lights, and dash lights no longer dimmed every time a bass note hit hard at lower engine rpm. I recommend to every one and anyone who'll listen, that it just makes good sense to have one of the installed. Installation is relatively simple and fast, and it pays off in the long run by saving money on replacing some very expensive components in your vehicle.

The one that was in my car that I bought used started beeping and had a high pitch buzz. I don't know much about car audio, but swapping it out for a new one of the same model did the trick! Happy with the quality of the product.

Using as a short term power for a Raspberry Pi to handle shutdown when power is removed. WIth split ring pliers, you can remove the voltage and alarm board on the top. This reduces the drain of the cap considerably. WIth this gone, self discharge of the cap is 0.01V every 1-2 sec. Without the board removed, it drops 0.1V every few seconds. I'm using a 5V buck converter to power the Pi. I get 15 seconds of run time from 12V before the Pi undervolts and shuts down. This gives me enough time to do a shutdown and not corrupt the file system with a power removal.

I wish I could give this product 0 stars. Received my first capacitor. The charging directions didn’t work, but I work with electronics so I charged it properly anyway using a test lamp. It held no capacitance and would dip below 12 volts on bass hits powering a relatively small 500 watt amp. I contacted the company Feb 11th for an RMA. Didn’t receive a replacement until March 2nd (in fact they didn’t even mail my replacement until Feb 24th when I contact them again asking where it was). The second capacitor wouldn’t charge past 10 volts so I didn’t even hook it to the main power out of fear it could blow. Ended up returning the original to Amazon for a refund and having to go out of my way to recycle the replacement. Ultimately it was a waste of time and I ended up using an old Scosche 500k capacitor while I shop for a reliable 2f cap. Fwiw the 10 year old 500k Scosche has more capacitance than either of these “2 farad” caps and charged properly the first attempt. Save yourself some time and frustration and buy something else. The service is sub par and the product is even worse than their service.

The blue led flashes so you think youre getting pulled over and the voltage display numbers are already failing after 2 weeks of use. Cheap though...

👌👌 excelente Amazon todos los artículos que me envió Amazon cumple

Awesome, works beautifully

Buen funcionamiento

Eficiencia continua

Muy buen producto.
