I think the type of capacitors you are talking about are used to keep power spikes down. If so they are going to be wired in between the battery and the sub amplifier(s). The cap will need to be as close the amp as possible and be grounded with a separate heavy gauge cable, preferably to a different spot than your amps ground. The power wire from the battery will be connected to the pos. terminal on the cap. A second lead will run from that terminal to the amps pos. input. With the cap as close to the amp as possible and the cables from the cap. to the amp as short as possible and as thick as needed for your power requirements. Your ground wire should also be thick (heavy gauge) and short, terminated on clean paint free metal surface of your vehicle. The power wire from the battery should also be as thick as needed-more is better here so don't be afraid to spend some money. THERE IS ALSO A VERY IMPORTANT NOTE ABOUT CAPACITORS-you should slowly charge the cap before connecting the lead from the battery, not doing so is DANGEROUS. You can use either a 12volt light bulb or a small resistor to charge the cap. One side of the resistor or the light is connected to the battery lead and the other to the pos. of the cap. If you are using a light bulb it will indicate charging by lighting up. If you use a resistor you will need a voltmeter to check your progress (be carefull with either of these methods they can be a little hot on your fingers). When done charging, hook up the battery wire and you should be good to go. If it was done right and you have the right size caps for your setup the following things will occur and not necessarily in this order.

1. Your headlights are no longer dancing to the beat.

2. Your rear veiw mirror is harder to see through.

3.You will not have to replace your alternator or battery in your car anytime soon.

4. A smile will appear on your face as you plan your next move towards world domination!

Well maybe not the last one.

Hello I recently bought an Hyundai Iload and want to know if I can connect a subwoofer to the factory unit?

Yes, you can. You will need a hi/lo converter to use the high signal from one of your vehicle's speakers and convert it to a low signal for an amplifier. Your will need an accessory power source (switched with the car's ignition or accessory on) to act as a remote turn for the amplifier. You will need an amplifier kit. The kit usually comes with a power wire, ground wire, remote turn on wire(blue), RCAs to connect the converter to the amp, a fuse for the power supply at the battery and speaker wire to connect the amp to the sub. Now, all you need is the sub.

Replaced battery in my car on wedenseday car started right up got home turned car off car wouldnt strt back up took battery out put it back in car starte right up turned car off same problem occured

Ok, if you have a subwoofer system, ground wire going to the battery from the AMP is draining the battery due to improper wiring. Your best bet would be to contact a car audio shop or BETTER YET, go to one. They will definitely be able to help you out.

How to assemble boss sub woofer,any?

If you have already bought the subwoofer, you will need to buy an enclosure for it. As well, you will need an amplifier and a compatible receiver for the amplifier.
Once you have all of these components, you will need to wire them all together. For this, you will need a pair of RCA cables to run from the receiver to your amplifier, a power wire to run from your amplifier to your battery, and wire running from your amplifier to your enclosure/subwoofer.

First you'll need to buy a good quality amp wiring kit. For the torture your battery receives, get a power cap. The higher the farad the better off. And as for sound quality use really good RCA's and speaker wire. Try to keep the amp as close to subs as possible, and speaker wire a the necessary length. Not to long. Be sure to have a good ground.

Power wire

You should run a new power wire to the battery or fuse box from the Sub. For safety there should be a fuse on the cable at the battery or fusebox end.
