Great Cap by a Fantastic Company
By Jeremey
First thing is first... if your car can't handle an amp then a capacitor won't fix your problem.Do your research on capacitors before buying one because you "think" you need one. The digital aspect allows you to see the voltage provided to your amplifier. If you see your voltage dropping then you know you have a fault somewhere in your setup. The capacitor helps stabilize your amplifier by providing it with the extra power needed during heavy bass.I would highly recommend upgrading, at minimum, your battery to an Optima Deep Cycle Yellow Top. Autozone or Oreilly's can tell you which one you need. Do not buy the red top!For those wondering what the big 3 upgrade is it consists of: upgrading your alternator, your power cables from stock to at least 4 gauge if not 0 gauge, and your battery. Most people don't need to go that far for a basic subwoofer install. I.E. an amp of 500 RMS and one or two subwoofers. If you get into the 1000 watt RMS range then you need to seriously upgrade your car components.By using a capacitor you prevent harmful discharges from your battery. Keep in mind when installing the capacitor that you need to ground it seperately from the amp. In other words black ground cable from amp to vehicle and black ground cable from capacitor to car. DO NOT run a ground cable from amp to capacitor and then to your car. You can cause the capacitor to short out.This capacitor does not get hot. I had it mounted in a very tight space in my Silverado without any issues.As a side note I currently own an 03 Infiniti G35. The stock alternator has 110 amps available. I'm running an Alpine MRX-500 with two Type-E subwoofers at 250 watts RMS each. I'm giving each sub approx 300 Watts RMS as my amp is rated at 605 RMS. Nice thing about Alpine amps is that they out perform their advertised specs, usually. I have an Optima Yellow Top. I consider this a basic setup as my alternator can handle the small system. The capacitor helps to prevent the previously stated issues.Crutchfield sells Tsunami brand capacitors which are good and well but I've always used Alpine or Rockford which is the reason I chose this cap. I've owned it for 3 years and it's still running strong. ENSURE you charge it before install!Lots of random info in this review bottom line... Can't go wrong with this capacitor at $70.

Does its job and easy to install
By Steve Martin
Opposite of the previous reviewer who is not reviewing the product at all, I found it did exactly what I wanted it to do. It was easy to install, and added the value that I was looking for.

By CJ
Let me start out by saying this isn't going to solve a situation where your pulling 150 amps and your car has a 50 amp alternator. If your power is matched well with what your car can handle the cap works very effectively to stiffen the cars voltage. This is especially helpful with subwoofers where the bass note usually cause the sub amp to pull a large amount of juice. This will be right there to help stop the voltage from dipping. When the voltage dips the amp works less efficiently and when the amp isn't working efficiently you have reduced power. Voltage dips also lead to heat build up(due to increased amp draw) and things breaking over time including your cars electrical system. The voltage meter is handy when tuning although it's also helpful to get a reading at the battery, so you have the true volts across its cells. The design will also work well in many situations if you want to display it, or you could just as well hide it for the stealth install.
