I purchased this product to help with my headlights dimming during very low bass ... Did what I needed it to, strongly recommend it.

I got this to try because I was gonna run a dual amp set up and wanted to relieve some of the stress on the electrical system. I decided to run a single 5 channel instead so I never used it and Sonic was very allowing on returning it. it was however a very good price and somewhat visually appealing so no cons.

I would recommend this capacitor to someone in need of one. However it is extremely important to ensure you get the proper farad rating for your application. Not doing so will result in poor performance and unsatisfactory results.

I have had no problems at all with this, the instructions told me step by step what to do and it works great. No problems, it doesn't run down the battery at all and keeps my amp and subs pumping out that music. Will definitely recommend this to anyone looking for that extra boost of power for there system.

Good product. I use it for my mids and highs amp as I have a large system and it keeps the amp powered nicely. I would recomend this product.

this cap is very good,can't ask more for the money

I am using this for my 1200 watt amp (600 watts rms) and i have no headlight or interior light dimming what so ever,and i am still using my 10 year old stock alternator. but i also have the big three uprage with 4 gauge wire and brand new battery so that halps a lot too.

I would definitely recommend this capacitor to anyone who doesn't want to spend their bank on a capacitor. great product, works as advertised, and looks cool too! and it can be mounted upside down, side ways, anyway you want to install it. mines upside down and no problems what so ever.

I used this for my 1400 watt amp. It really helped my dimming lights. Now I have enough power to do it all.

Everything I needed to set this up was right in the box. Came with the resistor and everything.

Thanks guys--

I wrote a good review earlyer on this product but now I have changed my mind after only a few months use. I have been using it for a few months then the meter would turn off and on, then kept reading really low voltages with NO music playing.

I would not recommend this product at all. I had everything hooked up correctly and the SOB starts to pour out smoke. After that you had to hit it with a hammer to get it to work. Waste of money. Get a Kicker. Strong, durable, and won't fry.

Theres really not much you can say about a power cap. For the price of this product, it does what is says it does. Corrected my headlight dim when heavy bass hits. Very good product!

For the price you cant beat it. It performs really well and i can tell the difference with the cap than without it. Need a cap for a good price this one is for you!

I highly recommend this cap for 1000-1500 peak wattage. Came in 2 days with the resistor. Works great! I highly recommend.

I ordered my Cap & received it superfast. This is my 3 order from Sonic & they have been great. I have been using my capacitor for the last six months & it performs great. My system power has been very stable & I look foward to picking up a few more things as soon as I have time.

This works just as well as my rockford fosgate capacitor that I paid a lot more for... my lights don't dim anymore and it looks cool. Don't even worry about it, just buy this.

Works perfectly!!

Had my 750watt rms amp hooked up and was putting out about 824rms, just killing my car, the speedometer needle would drop when the bass hit. I added this and dimming and everything about quit, dash lights still dim slightly but never drops below 12.4v now.

Hooked up correctly and seems to not work...installed different ways for three hours and I am pissed with this cap guuna get a Kinetik batteries instead

Highly recommend. This cap is only rated to handle amps up to 1000 watts. Right now I've got only one of these on my 2000 watt amp and it does a good job. I will be buying another one to make up the difference for the watts I have. This thing doesn't drop below 13.0 volts even with my 2000 watt amp. I love Power Acoustik.

I love this product I bought it about a year ago and its still working good as new I love this capacitor totally worth the cash

i purchased this cap to help me with a small 500 watt amp and didnt help at all i would personally buy a secondary battery if u were to run a large system

From what I have heard, this is a good capacitor. That guy who said he wasn't sure if it was the cap or his system, some amps and most recievers have a autoshut off mode on it if the wiring is off so it does not damage anything. I highly doubt it was because of the cap.

I instaled this cap because I have two amps in my van producing over 2700 watts. It was easy to install and looks awesome too.

i bought this capacitor and i'm not too sure if i bought the wrong capacitor or if its the capacitor itself. every time i up the bass on the amp or head unit it completely cuts off the bass and i have to lower down the bass for the bass to kick in again.

i installed 2 power acoustik amps (ovn1-2000 and ovn4-840) and i have 1220 watts rms. i was having lights dim at high current draw. i first added a optima red top and it stopped. the only thing that was killin me was my interior roof light was dimming a lil bit. added this and it did the job. i took off the plastic and painted it black for my stealth look. good cap!

I really like this cap for the price. I did not come with any extra connectors though. so it is sitting in my car doing nothing till i can get more connectors. But it is a great product for the price.
