Solar Info: The Down Low on Everything Up High
I use one of these for identifying which conductor is live whenever I’m doing any home maintenance. It also comes in useful for checking whether there’s a break in a power flex and where the break occurs. It’s always a good idea to use a neon tester to double check that power is definitely off when doing any electrical maintenance. When asked, Fluke, who are a leading manufacturer of digital instrumentation, recommended the Fluke model for general purpose use in the home or for car maintenance. This is an excellent meter and can measure AC and DC volts, resistance, check continuity and diodes. The meter is auto-ranging, so ranges don’t have to be set. It is also a true-RMS meter.

Why Car Audio Capacitors Don’t Work Updated on March 28, more Introduction Many car audio fanatics will use a power capacitor as an alleged secondary, passive storage device to supply current to their amplifiers. They typically come in cylindrical shapes that are three inches in diameter and about a foot long, though other shapes are also available.
They have a positive and negative terminal and possibly a third remote turn-on terminal that turns an LCD display on or off. Do these devices work as advertized? Capacitors are electrical buffering devices. They are not current-generating devices. Many will swear that their headlight-flickering issues went away or were reduced after the addition of a capacitor. We will explore this phenomenon in detail. But, they have a very detrimental side-effect when applied to current-limited automotive systems.
Your car audio system is running mainly off your alternator, not your battery because its voltage potential is Since the alternator has the highest potential, it will supply the demanded current up to its point of saturation, whereby the battery takes over to supply the extra spikes of current demand. But in such a saturated scenario, the voltage supplied to your audio system has dropped substantially. The addition of extra batteries is only a limited band-aid fix to the problem.
There is only one solution:
ASK A BRAND
The current drawn isn’t continuous, it spikes and dips according to the music you play, and the volume. You need to overrate the PSU substantially, to allow for these spikes – not doing so will cause the power supply to burn out with extended use, or may constantly trip its overload protection mechanisms. Do NOT exceed As rexter said, the actual battery voltage is higher than 12V.
Some of the cheaper switchmode power supplies give out really dirty voltage – this comes through the speakers as hissing, pops, high pitched squealing, clicks etc. Hope thats clear enough Aug 21, ,
Feb 06, · You are best off using two amps, one for the speakers and one for the sub(s). You can do this for under dollars if you are smart about what you buy. Use a distribution block to split the power wire coming off the battery, run a remote wire to the first amp then off that same terminal on the first amp, bridge another wire to the next amp.
One thing I learned pretty early in life is that speakers are not meant to be wired together in a haphazard manner. In fact, whenever you plan to connect more than two speakers to a two-channel amplifier — or more than four speakers to a four-channel amp — there are a few things to consider, not the least of which is the amps ability to handle low-impedance loads. Ignoring the basics is like playing Russian roulette with your amplifier: If youre lucky, itll drive the speakers without incident; if youre not, the amp will fry.
The great thing about a multiple-speaker hookup is that once you master only two basic wiring procedures — “series” and “parallel” — the world is yours to conquer. When you know how many speakers youre going to use and the impedance driving capability of your amplifier, youll be able to select a wiring scheme that will deliver the best sonic and electrical results.
Do you need an amp if you hook up subwoofers in your car?
How to find your Total Score? Add up the points from each column of the above table to find your Total Score. A Detailed Look at your Conditions Determining questions on adding an amp:
Jan 23, · You’d have to extend the positive battery cable if you want to mount it inside the car. You just cut the wire in half and put connectors on both ends and hook each end up to the studs on the switch. here’s somewhat of a diagram.
When jumpstarting a car you essentially give the dead battery just enough boost to start the engine and then rely on the alternator to charge the battery the rest of the way. When using a battery charger, you allow the battery to charge all the way before it will be used again. This should answer important questions such as what the voltage requirements are for charging your battery and whether or not you should remove it from the vehicle before charging.
There will be a manual with your battery charger that provides details for the appropriate use of the charger. Working in a well-ventilated area will help dissipate the hydrogen gas that batteries generate from the sulfuric acid within their cells. Also, make sure to keep any other volatile substances, such as gasoline, flammable materials, or ignition sources flames, cigarettes, matches, lighters away from the battery at all times.
Glasses, gloves, and other protective gear is a good precaution. Hydrogen released within the battery quickly converts to a gas and expands, this can cause the battery to explode if venting mechanisms fail. These accessories draw power from the battery and should be turned off before removing or charging the battery.
Most batteries will be found either under the hood of the vehicle or in the trunk. It is also possible that your battery may be under the rear seat, and sometimes the battery can only be accessed from underneath the side of the car. There are a few ways to tell which is which: Compare the diameters of the battery posts. For most batteries, the positive post is thicker than the negative post.
One-Wire Alternators: Are They Better Or Just Easier To Hook up?
But if you insist on using an amp meter, here’s the information. The most important feature of the amp meter is that it is a low resistance high current device. It must be installed in series with an electrical load to limit current flow. If you were to wire the amp meter directly across the battery as you would with a volt meter the amp meter would immediately pass so much current as to fry the meter, almost instantly.
Com to hook up with no rca to the amp, by alex porter. A power and car body. In one to amps don’t have the remote wire it is watts. Calling all positive wires together we will want to reach a watt 2-channel amplifier and.
Marine stereos are designed to be used on Boats so they run off of 12 volt battery power. But what if you want to use a marine stereo in your hot tub, on your patio or by your pool and you need to be able to plug it into a wall socket? You will need a 12 volt power supply like this one that can adapt the power from your home to the type of power that your stereo can use.
Not just any 12 volt adapter will do. These little power supplies that you commonly see, I call them wall warts are not going to do the job because they don’t provide enough amperage. Most of these are less than 1 amp and that is just not enough. A typical stereo head unit will need about 5 amps of power. If you want to crank up the volume for parties and plan on using a powerful amplifier, then 5 amps likely won’t be enough either.
We do have power supplies available that offer up to 30 amps. Some people will use computer power supplies and they work great. This 5 amp power supply that we sell works well, particularly because it has a rubber gasket that seals the case closed so water can’t get in. That makes it good for use outdoors.

The Prius in ready mode will keep the traction battery and 12 volt battery fully charged automatically as long as you have gas in the tank. In the ready mode you will be running your equipment and the 12 volt equipment in the car off the power provided by the dc-dc converter. As was stated before you will have to make sure the amplifier is really off and not drawing any current when you turn off the car and leave the ready mode. Additionally you cannot run the car in accessory or ign on mode for very long if your amplifier is on as the Prius dc dc converter doesn’t operate in these modes.

Is your amp bridgeable and how many channels does it have? I have a watt 4 channel crunch amp. The good thing about 4 channel is you can have a pair of sub-woofers bridged to channels 1 and 2 and control your bass. Then mids and highs bridged off of channels 3 and 4. So yes you can get more power out of certain amps by bridging. I have a nice Rockford fosgate system hooked up in my house.
Just my Rockford amp is watt peak power and RMS.
How do you wire speakers and tweeters off of a 2 channel amp?
Here’s how to test the capacity of a 12 volt battery with an inverter, a lightbulb, and an electric clock. This can be pretty important to know. Will your battery last long enough to show a feature film at your guerrilla drive-in theater? Will your marker light stay on all night on your boat? Internally, the plates just aren’t the right shape to get long life from deep cycles and still put out enough current to start a car.
Sep 07, · get a high amperage AC to DC converter, splice the wires, and wire it up to a car amp, then hook speaker up to the amp #4 Joemonkey, Sep 7, shuan24 Platinum Member.
Trim panel removal tool Step 1: Installing the 12v Power Wire In your amplifier wiring kit, generally a red in color wire is the longest one, which is the 12v power wire. You need to pass the wire through the firewall. Start from the battery and pass on to the amplifier. However, do not connect the wire to the amplifier or battery yet. Removing the Stock Stereo Remove the stock car radio from the dashboard of your car.
Make sure that you carefully remove the screws that hold the stereo in place ensuring that no wires are cut. Installing the Remote Wire Once you remove the stock stereo, you will see a blue and white wire, which is basically your remote wire. This wire is located at the back of the stereo deck. Get the remote wire in your wiring kit. Once you splice it, solder this wire to the remote wire of your stock stereo. After this is done, run the remote wire through the dashboard and the door jam.
Once this is done, you can now run the wires back into the amplifier. Connecting the Subwoofer to the Amplifier With the speaker wires, connect the subwoofer system wiring to the amplifier.

Improve your stereo’s sound quality and increase its volume by installing an amplifier. Here’s how to do it. If you’ve ever cranked up your car’s factory stereo, you’ve likely heard some distortion. This is common when your main unit is powering your speakers. Adding an amplifier lets you increase the signal sent to your speakers, which in turn limits or outright eliminates sound distortion when you turn up the volume.

Plan the Location of the Car Stereo Equalizer First of all you need to think about where you want the car stereo equalizer to be installed in the car. Where does it look the best, is there enough room where you think it looks the best, or do you need to consider installing it in a different area of the car. Run the Main Electrical Wiring Wiring a car stereo equalizer can be a rewarding experience when done the right way. After you have the car stereo equalizer mounted, you need to run the main power wire, usually a 16 gauge red wire to the main power, or switched power wire in the fuse panel, you will need a test light for this.
If you want the car stereo equalizer to come on only when the key is in the on position, you need to locate a power post that only has power when the key is on. Hook up your main power wire from the equalizer to that post. Run the Main Ground Wire After you have run the main power wire, you will need to find a place to mount the ground wire. A plastic mounted ground wire will never make a good ground. Things to remember when wiring a car stereo to an equalizer Make sure that you have enough room to mount the unit where you want it Try doing a fit up before you drill any holes Run the main power wire from the equalizer to a power output in the fuse panel Mount the ground wire correctly, make sure that the ground wire is mounted to metal Now the equalizer should be installed where you want it, with the power, and ground wires hooked up Step 4:
