Features

Overview: This T-Spec v6-series digital capacitor will improve the performance of your car's electrical system by acting as a buffer between the alternator and your amplifier. Stored energy from your car's electrical system is held in the cap and quickly released to the amplifier when needed. High current demand occurs when the music you are playing contains a loud, transient, deep bass signal.

Capacitance: This T-Spec v6-series digital capacitor has a rating of 1.5 farads. While you can never have too much capacitance, it is recommended that you use a capacitor with a minimum of 1 Farad for each 1000 watts of amplifier power.

Terminals: The capacitor features an impact-resistant polycarbonate cover with two terminals on the top that can be tightened/loosened with the supplied 5mm Allen wrench. You should use power and ground cables that are equipped with ring terminals with 1/4" diameter or larger holes.

Voltage Meter: This capacitor has a digital voltage meter on the top to help you monitor your electrical system's performance. Once current fluctuation ceases, the display will turn off and go to sleep. In order for it to turn back on, it must sense current draw again. 

Reverse Polarity Protection: If the capacitor is wired incorrectly, you can damage your equipment or electrical system. To prevent this, the capacitor has an internal relay system which disables the capacitor and triggers a buzzer to sound.

Resistor Bulb: The capacitor comes with a 1/2-watt, 1000 ohm resistor bulb which is used when initially charging the capacitor, and to discharge the capacitor when removing it from the system. You should keep the resistor bulb in a safe storage location when not in use.

Mounting System: The cap comes with a simple mounting system that lets you mount the unit vertically or horizontally, using the four supplied self-tapping screws.

Q
Is 1.5 farad too much for me?
[ Mark  Aug 06, 2018 ]
2 answers
A
It depends how many amplifiers you have and how big the amplifiers are.
[ Vasilis  Aug 06, 2018 ]
A
It's never too much it can only help you battery handle the draw from the amp. What is your set up that will ultimately tell if this is overkill or just right what type of sub or speaker and wat type of amp rms and peek. Mono or multi.
[ CARLOS  Aug 06, 2018 ]
Q
Can you remove the voltage meter?
[ Joshua  Aug 04, 2018 ]
1 answer
A
I personally haven't removed it but I don't see why you couldn't you would just have to cap the wires just to make sure you didn't cause any kind of spark
[ William  Aug 05, 2018 ]
Q
Im running an alpine 85watt x 4 channel amp. And an infinity kappa 600 amd a alpine sum amp combo (8") it seems that turned up loud the sub cant be heard as well. It seems like it's being overrun by the 4 channel amp. I have a huge battery. Do you think i need a compactor on sub amp or i just dont have enough amp??
[ Ricky  Apr 19, 2018 ]
1 answer
A
You don't need a combo, use one amp. See what the sub rms watts are and get an amp that will cover it. Ex: 1 sub rated 500 Watts rms = 1 amp rated at least 500 Watts rms. I like to always go a tad higher to give breathing room for each component. Hope this helps, good luck
[ Carson  May 04, 2018 ]
Q
What gauge wire does this capacitor support?
[ TimelessLogic  Mar 08, 2018 ]
5 answers
A
I installed the capacitor in system in my daughter's car. It supports a 4 gauge wire. No problems so far.
[ Charles  Mar 15, 2018 ]
A
I'm not 100% sure I believe I have a 2 or 0 running to mine. Just need to use the correct terminal. It can support any wire you throw at it main thing is the correct terminal size crutchfield should have specs on the stud size.
[ Justin  Mar 15, 2018 ]
A
I'm using 4 gauge wire. Just ensure you use the proper terminal connectors.
[ JAMES  Mar 15, 2018 ]
A
It depends on the size of wire connection used to attach wire to capacitor, the top of the capacitor has two Allen head bolts that thread into the top of it, one for power in and one to amp. 12 gauge to 4 gauge or even a little larger, but for that size capacitor 4 gauge would be perfect I think.
[ CRAIG  Mar 15, 2018 ]
A
I ran 0 gauge no problem!
[ George  Mar 15, 2018 ]
Q
Would this be good for my system ? I have it running off a Kicker ZX-700.5 channel amp which puts out 70x4 RMS and I have my subs wired for 2-olm which makes this amp push 410 RMS to my two 10's in ported box. Thank you kindly for reply.
[ Joshua  Jan 07, 2018 ]
1 answer
A
I think it would be adequate. I just power two 12in Kenwood Subs in a sealed box. With a Sony Xplod 1,000 watt. Just make sure to give it a good ground and charge it up before hooking it up. It's in the directions. Read them Cheers!

Q
So what if My 1.5-farad capacitor with red LCD meter display is still lit up even tho my car is turned off?
[ Percy  Mar 22, 2017 ]
2 answers
A
The capacitor stores energy, so it will stay lit even when your car is off.
[ chris  Mar 23, 2017 ]
A
I think it's normal. Mine does the same thing. It's under the rear seats and I notice its lit whenever I get in or out of my vehicle.
[ KEVIN  Mar 23, 2017 ]
Q
Do I need two sets of gauge wire one for my subs an one for the capacitor or I can use the same gauge wire I'm using for my amp an subs?
[ Percy  Mar 02, 2017 ]
1 answer
A
Gauge is wire size. Don't really understand your question but your going to run power wire from battery to capacitor then power wire from capacitor to amp. Then ground wire from capacitor to a good ground & same with amp. Hope this answers your question
[ Nick  Mar 05, 2017 ]
Q
I'm installing a new system in my 2005 f250 I have a 600 watt amp for front and rear speakers and a 1200 watt amp for my subs. my truck has two batteries its a diesel. should I and can I install a capacitor in it?
[ chris  Feb 11, 2017 ]
3 answers
A
Yes you can run a capacitor with this setup. I would suggest installing one on sub amp just to take some load off electrical when sub hits.
[ Nick  Mar 05, 2017 ]

Yes. I am running 3 high current amplifiers by Hifonics. 100 watts x 2 @ 15 amps, 140 x 2 @ 30 amps and a mono amp 200 x 1 @ 30 amps. Works great.
[ Cyprian  Mar 21, 2016 ]
Q
If my battery dies do I need to re-charge the capacitor?
[ Mike  Sep 21, 2015 ]
4 answers
A
No. Your capacitor will stay charged as long as your alternator is good.
[ DAVID  Sep 26, 2015 ]
A
Im not an EE, but capacitors store energy and it acts as a buffer between your stereo and the electrical system in the car. If your Battery drains, and/or is replaced, it will automatically store up energy again once you fix your battery. Capacitors are in appliances, computers and a whole bunch of things.
[ MICHAEL  Sep 23, 2015 ]
A
Depends on how long your battery is dead. If you already have it installed, just replace the battery and it will draw what it needs. If you're reinstalling after installing a battery use a 1k-ohm resistor to trickle charge it. honestly you don't have to trickle charge it but you'll get a large spark if you don't.
[ ROB  Sep 23, 2015 ]
A
NO, I had to buy a new battery about four months after I bought my capacitor, alp I had to do was hook up the new battery and I was good to go.
[ RICKY  Sep 23, 2015 ]

Q
Can this Cap power 2amps simultaneously? I want to run 2 amps one JL 600Wx1rms and the other a JL 75Wx4rms,or do I need a cap for each amp?
[ steve  Sep 07, 2014 ]
3 answers
A
Yes. Run the power wire connection from your battery to a power block, just connect the capacitor to the block and the amps to the block as well (the amps will draw from the cap if it needs current. I bought the capacitor after a lot of research and concerns with my cars electronics. I ran into some power problems that wound up being a bad ground from my amps to the car. Along the way I purchased a new XS power battery which helped a lot. I have an F150 and the alternator kept up with the demands of my system (I have alpine 600w x 1 sub amp, and a 100w x 4 amp). I don't even get a voltage drop out of the capacitor now even if I am running the system and all of my car's electronics. Long story short, I don't know if I needed the cap in my truck with the new xs power batter, but I think it was a smart move .
[ COLIN A  Sep 09, 2014 ]
A
yes it can thats how i have it set up now just get yourself the wire connectors and little extra wire and youll be ok
[ AFRIM  Sep 09, 2014 ]
A
yes it can. the capacitor isnt what is powering the amps but it acts as a storage device and it works great.
[ THOMAS  Sep 08, 2014 ]
Q
I all ready have a system installed in my car but want to keep the lights from dimming when it's turned up. Does this come with wiring? If not what wiring will I need. I'm running 4 gauge wire to my amp in the truck. Also should this be installed next to the battery or right next to the amp in the truck?
[ Derek  Dec 18, 2013 ]
4 answers
A
I installed one after I had installed my system bc of the headlights dimming. It's right next to the amp. Installation wasn't too complicated. My headlights still dim slightly but not as bad as before the capacitor.
[ KEVIN  Mar 23, 2017 ]
A
It should be installed as close to the amp as possible.
[ Eric  Sep 30, 2016 ]
A
What size amp are using too?
[ Nick  Jan 11, 2016 ]
A
You will install this as close to the amp as possible. You will need wiring as big or bigger than your 4 gauge and you will need a distribution block to wire this in. This does not wire in line with the amp. And make sure you read the instructions on hook up, charging and discharging.
[ TYLER  Dec 18, 2013 ]
Q
Which terminal hooks to the battery? The + or ~? Positive or negative?
[ Michael  Dec 18, 2013 ]
4 answers
A
positive
[ JOSEPH F  Dec 18, 2013 ]
A
Positive to battery positive.
[ DAVID  Dec 18, 2013 ]
A
Connect the power wire from the battery to the positive terminal on the capacitor. Use heavy gauge power cable, number 4 car stereo power cable if I'm not mistaken. Run the power cable to the amplifier from the positive terminal of the capacitor. Simply ground the negative side of the capacitor to your chassis, make the ground #4 power cable also and as short as a lead as possible.
[ Billy  Dec 18, 2013 ]
A
The positive(+) terminal hooks to the battery. Take time to read the instructions for this item. One thing I didn't notice is that you will need a distribution block to wire this in. You don't wire this in line with the amp. Hope that makes sense. The instructions will tell you how to wire it in.
