i picked up this RF cap from my friend a while back and its been laying in my room ever since. i got bored today and i charged it up. now all i need to do is hook it up. i have a 1400 watt amp hooked up to 2 digital audio subs. can somebody help me with this

 

no one knows how to do this?

 

Hook it in parallel with the sub amplifier power wires, keeping the wires as short as possible.

 

theres only one power wire

maybe im missing the concept

BTW discharge the cap first, remove the fuse on the power wire, wire the cap, then charge the cap, reinstall fuse, good to go. 94

 

Actually you want the negative to go directly to the amplifier don't run it to where the amplifier is grounded. I think this is what you meant to say. You want both wire as short as possible. Ground is still a power wire current flows throught it. So as already mentioned connect the + on the cap to the + on the amp. Connect the - on the cap to the - on the amp.

Remember current must complete a loop it must start and stop in the same place. If you have a short + and a long - the current still has to flow back through the long - wire. Which is bad, there are parasitics associated with that.

You don't need to once its hooked up to a constant power source it stays charged.

 

so it needs to be grounded to a different place than the amp is?

 

no . i ran the ground to my cap and then from the cap to the amp. works great.

You can run the ground to the cap and then to the amp, just like the power, or, [ and I think its better] ground it at the same place as the amp is grounded.

so then you can hook the ground wire coming from the amp to the terminal on the cap? then ground the cap to the car?

 

yes

alright i can do that now how the hell do u do the light bulb thing? sorry im an idiot

[ I have evan removed and used the domelight bulb] all you have to do is put the bulb in series in the power wire, I do it at the fuseholder, [with the fuse out] touch the pos. (+) of the bulb, [ the pin on the bottom of the bulb] to the batt. side of the fuseholder, and touch the neg. (-) part of bulb, [the ground or side of bulb] to the wire going to the amps/cap, when you do this the bulb will light up bright, then slowly get dimmer till it gos out, or almost out, cap is charged.

PS Do not hold bulb by the glass part, it will get HOT, also its only 12volts, you can NOT get a shock. 94

 

alright well my amp is already charged up, (sombitch), how do i discharge it?
