BOSS Audio Systems CPRD2 Car Capacitor - 2 Farad, Energy Storage, Enhance Bass From Stereo, Warning Reverse Polarity Tone, Voltage Overload Low Battery

**UPDATE** - Here we are almost 2 years later. (Normally with the PCX models, they would have FAILED, into permanent circuit protect by 6mo to 1yr)... NOT THESE... I bought a 2nd one for backup, and it's been collecting dust in my attic, cuz THIS CAP IS THE TRUTH! I honestly have more voltage, 14.7 , than when I first installed it.NO strain on my alternator, and only 1 battery replacement in this 2yr period! Caps will usually KILL a battery unless isolated by a relay, and stress your Alt. NOT HERE.. battery had a dead cell... alternator tested just as strong as a new one! Can I give this 6 stars?? This company should have me do a video for them, cuz I see nothing but PRAISE deserved for them. I could NOT be happier thanks to them! If this is available still, stop thinking and BUY IT! Of the 100+ Caps I have EVER owned, this has been the BEST performing, longest lasting, and TOUGHEST one hands down.** (Oh yeah I almost forgot..Never ONCE been into "protection mode!" --- God of Caps under $200!)** Let me start by stating, ive ALWAYS provided an honest and unbiased review here and everywhere i post a product review! So heres my analysis of this Boss 18cap, 18 farad capacitor. Overall? A+ ... NOW... lemme point you to a few indisputable facts about this product. #1. Any novice or pro level car audio or electrical consumer will realize this is NOT 18 farads... in reality its closer to between 5-8 farads. You can test it with whatever meter you want, but the way these are built (Hybrid Capacitors) is a combination of a standard 2-5 farad stiffening cap tied down to an additional circuit board with 8 separate high voltage rail caps much like those found in the Brazillian amps these days. Im not an engineer but the basic expl. Is that the board allows the main cap to exceed its normal storage capacitance by having these smaller caps recharge it much faster and thus creating a virtual bank of reserve power in a loop. #2. Dont be fooled... if you have owned the Power Acoustik pcx30, Planet Audio 20f, or several others that "Resemble" this (look at the connections, not the outside case) then you are correct, YOU DID OWN THIS! its the same cookie cutter design including the pcb board and voltage display. The one thing that sets this apart from the others is that THIS ONE the 18cap uses MUCH LARGER stiffening caps than ALL the rest! That 1 factor makes this SUPERIOR to the other clones. These caps themselves are nearly the same as the 4.4 and 5 farad Rockford caps which were phenomenal. So theres 2 of those to drive the build. Now for power. I am a pro builder and have been for 20 years. Capacitors have their place in audio IF USED CORRECTLY!. *NOTE: If you are trying to make a stock Acura Integra run a true 5k watt amp with 4 15's (eye roll) please leave this page and find your local alternator shop and get your electrical upgraded to a 300a or higher alt., get your Big 3 done, and load a couple XS batteries behind a relay! This will not help you!* **NOW.... if you are in my boat, (ex.) I have a 2020 Honda Crv which is under a spectacular warranty, and ANY modification to stock electrical will VOID my whole warranty, unless honda installs it. I can ADD anything i want but i cant remove anything. The honda CRV comes with a stock 90-120a alternator, but the electrical is maintained by less than 1/3 of that. I am running 2 Rockford T2d212, (1000 rms each) and a Brazilian 3k amp (tested at 3375 rms @ 2 ohms) plus an active EQ and Crossover. Ive got big 3 done, and all OFC 0 gauge run to the back. My voltage sat resting at 12.4 and 14.4 driving. Without the cap, i could hit some mid bass notes (the ones that drain voltage 45-55hz) and if at a light, i could nearly shut the car off if i was at 1/2 tilt. That said, an alternator was not an option (warranty void). Ive tested several of these hybrid caps and out of the ones mentioned above and some others... THIS ONE is the only one that proved helpful!. With this, my resting voltage is 14.5 and my driving voltage is 14.7. I can be sitting at a stop light with headlights on, AC blasting, system at 1/2 tilt, bass knob cranked, windows THROBBING and every car around me PISSED and my voltage MIGHT touch 13... never below 12 unless i am near blowing my subs. Final thought. WE HAVE A WINNER. Excellent design.. small footprint... supplements the variable juice needed to carry my system without invading my warranty commitment. Dont look further... start here.. you will not be disappointed. ***MAKE SURE U CHARGE THE CAP FIRST!!****

It's working as intended and it looks cool...but the Capacitor wasn't fully attached to the plastic inside, also it came inside another bigger box which had no bubble wrap or any type of protection, so you know the capacitor had been shaking inside through the shipment.

When taking out the box looks good when hooked up holes 14.7 right about where it should be that's what the very very hard load on it so it's doing his job. Very satisfied.

recommended for a 3500W Amp, was able to supply suggested power for 45 minute without pulling hard on batt. systems.

It came in on time and was as listed. Except the 1st one I ordered had a little issue and was defective. So I sent it back got refunded and bought a 2nd one, installed it as directed and also got helpful advice from the people at JL Audio on how they recommend I install it. So after triple checking everything I started up my car. It played nicely for about 7 minutes then it started to dim the lights when the bass hit and next thing I knew there was no more bass as the music continues and smoke barrels out of my trunk before I could even turn it off. Both of my 12's we're fried but nothing else was damaged.. mind you everything worked fine before installation then after installation of this cap18 it distroyed 2 subs that costed me $799.99 each. I tried to call and see if they would make it right with me or even meeting me 1/2 way in the price of the subs but they played dumb and kept saying "yes we can return the item and refund you it's cost no problem..." So if you want to take a very risky chance then by all means but I wouldn't advise anyone to buy this.

I like it it works very good and it looks good

Probablemente me tocó una unidad defectuosa. Eso es lo que comentó el fabricante. Pero seamos sinceros, con lo habitual que es "inflar" los números en este tipo de productos no quería repetir la experiencia y opté por otro condensador de otro fabricante. Sabiendo que me van a mentir, me quedé con uno que era más barato y de hecho mejor.La cuestión es que la capacidad real, medida con una fuente de laboratorio, rondaba los 0.5F (podrían ser unos 0.64 si tengo en cuenta el margen de error de mi equipo de medida, pero lo mismo me da). Eso es 1/7 de lo que anuncian.Todo lo demás es correcto. La ESR es baja, la pantalla se puede encender o apagar a voluntad, y la calidad general y los accesorios que vienen (como por ejemplo una resistencia para descarga y el kit de montaje), esa es la razón de que ponga dos estrellas. Eso y que el soporte por parte del fabricante me parece correcto, incluso si he terminado devolviéndolo.

Provato .. ottimo Capasitore 👌👌👌👌👌

non mi a soddisfatto non era funzionante non si caricava si è surriscaldato molto facendo saltare il fusibile rischiando di prendere fuoco il cavo.
