Metra Electronics T-Spec V6-1-5DDC Digital Capacitor 1.5 Farad Digital

Very nice product. Did everything as advertised. My amp is a RF 750 berth sheet states 928 watts RMS. I noticed my bass would reduce during big hits and saw my voltage meter tweak down a little bit. My light were not dimming but I knew the amp was drawing heavy. This capacitor is 1.5 farads which is good for approx. 1500 watts RMS give or take. Installation was pretty straight forward and comes with a small wired capacitor (looked like a light bulb) to pre charge the cap. The digital readout is nice and has two blue LED lights on on either side of the readout. The cap. will turn on any time there is a change In voltage. Like remotely unlocking your doors ( or obviously when the bass hits hard) At first I thought it was on all the time but after scoping it out it only comes on during the above mentioned. I can tell a big difference in the sound quality for two reasons. First I have an infinity amp running the front 6 speakers. Now that the RF bass amp has a steady supply of juice the infinity amp also has the juice it needs and actually is louder. As for the bass with this thing, it hits a lot harder more consistently. I saw the cap. advertised on Crutchfield. Not sure if they had any part in making it but it's the only cap. they sell. I know Crutchfield doesn't sell cheap crappy items so I thought I'd give it a shot I bought this on amazon for less then $50 worth it and would purchase again. Beware of the cheaper off brand units out there saying 2 farads for $30. You get what you pay for. Just sayin.

The media could not be loaded.  It has only been 1 day since I installed so we’ll see in the coming weeks how it holds. To start, the instruction diagrams were WRONG. It has the + and - terminals on the cap labeled backwards. I tried to charge the cap and my cars battery light came on. I used my multimeter to find correct polarity. Instructions says it takes 10-20 sec to charge. I had to charge mine for min straight before the full charge showed. It was pretty straight forward to connect. My headlights dont seem to dim “as much” when the bass drops. Will update review in the future to reflect any positive or negative experience.Btw: Have this connected to the 12” MTX sub amp ported combo from Amazon in a 12 Compass

I picked up this capacitor to ensure that the new stereo components didn't tax my electrical system. I read many mixed reviews about the need for a capacitor, but like the way it looks in the trunk :-) It was easy to connect, though I did take my time. Would recommend.

The product works as advertised. However, the resistor that comes with it for charging it was broken when I received it. Not a big deal as Radio Shack sells them (it's a 1/2 watt 1000 ohm resistor). But it was still a nuisance. Also, the instructions say it takes about 20 seconds to charge the capacitor. This is not true. It takes much longer. Possibly around an hour depending on the size of the capacitor.

Mine came used, it was scotch taped together and clearly had been returned prior. Amazon was the seller, I let them know and they took it back. That aside, it's the exact same unit as the 1 farad Install Bay capacitors, which are also junk. These don't hold a charge, you take it to 14.4v and unplug it and within 60 seconds they're down to around 6 volts. I tried hooking it up anyway and tested the volt drop on the amp before and after installation of this and it didn't do anything. If anything my results after were slightly worse. Save your money.

Purchased this as an upgrade for a new system. Using 2 orion xtr122d subs with an orion cobalt cb35001d amp. 2 ohm pushing about 1200w rms my voltage is very steady and my lights dont dim at all. I can have underglow, headlights, fog lights, and dome lights on and i get no dimming when the bass hits hard. great cap for a great price.

I like it and i love the display but just make sure when charging it that you let it charge longer than the specified time which i think was about 20 seconds, that was not enough time.

Took out the slight buzz in my speakers. With a total of 1300 watts coming from two amps this also stopped the slight blink in my dash lights when volumes are high. Best of all I know the voltage going to both my amps and of course the cool factor with the Spec graphic wrap.
