    • Good so far!
Style: 2 Farad
It was cheap enough for the size. I'm running 2500 watt amp on a 2500 sub. It has not failed one time and it does the job. So for us it's just fine for now.

    • Doubtful that it's 3.5F on my sample
Style: 3.5 Farad
Folks, I believe this a large ELECTROLYTIC capacitor. I don't think it's a bunch of Maxwell-style Supercaps or Ultracaps. That means this is one huge long set of metal foils with electrolytic paste between the layers. They are probably wrapped in a long spiral cylinder. For you EE types, all that foil implies a fair amount of series inductance which interferes with instant response to current spikes. Consider connecting a smaller electrolytic cap, say 4700 uF (with 35V working voltage), wired in parallel right across the big terminals or right at your load. That will give better transient response. I am an EE and my comments below probably apply to all similar competitive "Car Radio Capacitors". Here are some observations: [1] If this was really a 3.5F Supercap or Ultracap, it would be FAR more expensive. So electrolytic fabrication is a reasonable idea IF it is built and tested properly. Considering the low cost, I now have my doubts. "Sometimes you get what you pay for". [2] However, that electrolytic paste can dry out, leak and/or partially separate from the foil plates over time. That could happen especially in the hot trunk of a car heated by a nearby kilowatt amplifier.That deterioration of the paste causes less capacitance therefore you should test it often. It also means this product may have a limited life. If you open the trunk and find this cap hot, you might have BOTH reduced capacitance AND a safety issue. The "instructions" hint at all this by recommending that you make sure that there is no fluid leakage from the top vent. Note that high heat or foil separation damage could occur in shipping from China. Do they test them when they arrive?? Other damage could include hidden detachment of the foils from the internal bus. My packaging showed no damage. [3] I tested this and it is WAY less than 3.5 Farads. The supplied 51 Ohm resistor charges this cap using 12V / 51 Ohms or about 1/4 of an Ampere (250 mA), initial charging rate. I called SSL and they said it should charge in about a minute using the supplied resistor. Using only 1/10 Amp (100 mA - LESS than the supplied resistor), I only took about 15 seconds to charge to +12V. Less current and less time means this is MUCH less than 3.5 Farads. There is a very rough rule of thumb here: 1 Amp causes a 1 Volt rise in 1 second in a 1 Farad cap. Also note that the DVM decimal points did not blink during charge up as the "Instructions" state. [4] The two large silver plus and minus terminals go directly into the cap body. I cannot see any intervening MOSFET or other circuitry in series with those big terminals. That makes sense since a LOT of current might quickly exit this cap on power spikes. That direct connection implies that the little DVM is not required to use this as a capacitor (but is useful for SAFETY). I tried it both ways and there was no difference. As mentioned elsewhere, don't overtighten these terminals. [5] The small silver screw third "remote" terminal must be connected externally to +12 Volts DC. The remote is ONLY to power the DVM, nothing else. The return for this DVM board is the large minus terminal. My DVM seems to work okay. You may want to install a switch between +12V and the "remote" terminal if not already included in your radio. The DVM certainly eats a little current. Obviously the DVM will not wake up until there are most of 12 Volts at the remote terminal. All of this is NOT clear in the Instructions. Hey folks, why should a customer have to finish the "documentation" ?? If you order one of these, you may luck out and get a good one. I will not return mine because of the high cost of return shipping (it's heavy!!). Also I don't want to take a chance and get another lemon. I'm giving this one star because the idea is good but the quality control, as the customer receives it, is questionable. ... show more

The media could not be loaded. Don't listen to any of these reviewers stating that it's not a super/ultra-cap (which the product states its just a capacitor, nothing more) or the ones stating it doesn't last long and such. Chances are they either misused it or installed it improperly. I've had two of these 3.5uf capacitors providing supplementary power to two 1600watt amps, that's one cap per amp, I've had no issues. Fully charged they each hold about 14.7v, during standard music playing like using the radio tell drop to about 11.5v-12.5v, during heavy usage like playing heavy bass music it has only gone as low as 9.5v-10.5v. When my car is off, I can do heavy usage for about 45min to an hour and 1.5 - 2 hours of standard play. As soon as the car comes on, the recharge is instant. both caps have a low voltage tone which comes on when the voltage drops below 9v which I've tested by running both amps off of one cap. All in all, these caps are great for beginners or just those who don't have big systems. Of course, if you plan on going big, then I would recommend getting a super/ultra cap which usually looks like standard car batteries. But if you have limited space or you don't have the need for such high-end applications, these caps are the way to go. ... show more

I could tell from the pictures and the listed dimensions that this wasn't a small unit but combined with the provided mounting hardware I was surprised at the size. I bought it for a crew cab F150, and I already have two JL's under the rear seats along with an Audio-control 6XS crossover, one amp under one of the front seats, another amp in the dash and so on, so I squeezed it under the drivers seat but had to make my own mounting hardware. Besides that I've only had it installed a day but so far it works fine, and although its hidden the unit looks good-seems well made. I'll update if anything changes. ... show more

After installing this capacitor not only does my battery keep up but no more dimming of lights or cluster lights and the the bass hits way harder since my amp doesn't clip out!!!
