I looked up the info on the model ES and while it is one of the economy models it appears to have on board cpu since it can perform weekly battery tests and has a serial port to use with software to shutdown a computer when power fails. Overheating is definitely possible with these ES models as they don’t have any cooling fan and I don’t think they even have any vents. The electronics and battery are all in one plastic box, and they have small batteries so are designed with the expectation the inverter will run for a short time. All APC ‘smart’ UPS devices need to be calibrated to the batteries once or twice a year as the battery ages, so the processor can calculate and report the remaining runtime correctly via software or the front panel for those models that have one. As you have seen, the battery voltage under load is not the only determining factor for UPS shutdown in the ‘smart’ devices. It will shutdown sooner than expected if the battery voltage goes below a set threshold, otherwise the programming sets the shutdown parameters. One way to confirm the reason for shutdown is to connect a computer and use the software to monitor what the UPS is doing.
In-Car Speakers & Amplifiers
Speaker Connections for proper impedance match A note about amplifiers: You should always use the recommended load for your amplifier. However, if you must use a load other than the recommended load, here is a short guide. Most solid-state amplifiers would rather look at an open circuit no speaker at all than a load. Therefore, you can usually use a load that is higher than the recommended load.
Do not use a lower impedance load, as this could cause serious damage to your SS amp.

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:
How to hook up a subwoofer to a stereo system Hint: You don’t necessarily need a receiver with subwoofer output jacks. Subs can provide a foundation to the sound that few speakers can muster on their own. So adding a sub is not just about adding more and deeper bass; rather, a properly integrated subwoofer can improve the overall sound of the system. AV receivers feature bass management to direct the low bass frequencies to the sub and the midrange and treble frequencies to the speakers.
The subwoofer is hooked up to the receiver with a single interconnect cable.

Generators with high output are often used on construction sites and for arc welding in the field. Generators with moderate output are used for power tools, battery chargers, electric cookware and outdoor lights. Hooking up a portable generator is not difficult. In a short time, you’ll have electrical power at your convenience.
If the generator is installed on the bed of a truck, park the truck on flat ground. Remove the dipstick and note the oil level. If necessary, refer to the owner’s manual for the recommended weight of motor oil and add oil in small amounts until the oil level is at the “Full” mark on the stick. Tighten the cap on the gas tank. Alternatively, locate the button for the electric starter on the control panel and press the button until the engine starts.
Allow the engine to warm up for one minute. Typically, larger power tools require 12 or 15 amps. Power drills, jigsaws, battery chargers and lights require less amperage and in most cases, can be operated at the same time as larger tools. Depending on the generator, this may be a dial with numbers and a needle showing the current output, or a digital display.

Molex Connector Cut the molex Cable so that you have a black and yellow wire sticking out, for those who don’t know. Yellow wire is the 12v cable and the black one is ground. It is ideal you have something similar to what the picture below shows. Cutting Extension Cable Cut both ends of the Extension Cable so that you have three cables sticking out on both ends.
You will only be using two of the three cables. In my situation I had a Black, White, Green cable. I used green as my positive cable Yellow on molex and the white as my ground Black on molex. The third cable is not being used. I cut the sleeving on the Green and White cables so that the wire was showing. Paring Cables Take the yellow cable coming from the molex cable and connect it to the positive cable you choose in the last step Mine was Green , put them together and tie a wire nut on it.
Take the black cable coming from the molex connector and put it with the ground cable you choose in the last step Mine is white tie them together with a wire nut.
Understand how much power the current system can handle in terms of its electrical capability capacity. First, how loud do you want your stereo to be? However, having a lot of power available is good for “headroom”, which is the ability to deliver a burst of sound when the music asks for one. For example, an amp with 50 watts RMS per channel or smaller can overcome road noises and add clarity. Speakers or component sets rated with at least 75 watts RMS each can handle amps of this power.
I have a question about the power source to my car. i currently have an lc7 hooked up to my factory bose amp to connect my amplifier. (lanzar watt peak.) the Lc7 came with a knob to turn the bass up .
Just what is tone? What is a good tone and how do you achieve it? Which amps you should choose for your setup and how to get the tones you want. Check out part 1 and part 2. Amps People tend to prioritize guitars and a bunch of pedals and forget the importance of a good sounding amp. Choosing the right amp for your setup is crucial for getting the tones you want from your guitar and pedals. I strongly suggest that you buy a guitar and amp before you spend all your savings on pedals.
This will ensure the best fundament for your tones and playing. A tube amp consist of a pre-amp section that takes the small signal from your guitar and amplifies it enough to drive the power amp section. Most amps allow you to manipulate the pre-amp signal with a number of gain and EQ controls. The signal is then fed into the power amp, which gives the power to drive the speakers.
The amp could either be a head with one or more speaker cabinets or a combo, with the amp section and speaker cab combined. My best tip is that you spend some time checking out different models. How will you be using the amp?
How Many Outlets Can Be Placed on a 20 Amp Household Circuit?
It might be a generator, wind turbine or solar panels. There are plenty of ways to provide yourself with a reliable source of post-disaster electricity. There are all sorts of reasons why your power supply might not work. What if a stronger than expected EMP damaged your generator? With a few extra components, and a handful of basic tools, you can easily convert a standard vehicle battery into a power pack that will let you get some essentials running again.
Again try to keep this hook up as short as possible, and flatten it to the ground to avoid any trip ups! Set up the rest of your stuff. Make it feel like home, put out your plants, chairs, BBQ and all the objects of your RVing heart’s desire.

Car Audio Black Friday Sales! Even though speakers are active loads resistance changes with frequency , it is accepted to treat speakers as resistors with a fixed resistance value usually 4 ohms. By combining speakers in different ways, maximum amplifier output can be obtained. For example if a 2-channel amplifier is rated to deliver a maximum output of watts at 2 ohms mono bridged , then by hooking up two 4 ohm subwoofers in parallel, a total load of 2 ohms is “seen” by the amplifier, obtaining optimum power.
Parallel Resistance People commonly hook up two or more speakers to the same channel out of an amplifier in parallel. This is achieved by hooking up the negative wire from the amp to all the negative connections of the speakers, and the positive to all the positive connections of the speakers. By doing this, the load seen by the amplifier is lower.
For example, if two 4-ohm speakers are wired-up in parallel, then their total resistance will be half, or 2 ohms. If three speakers are wired up in parallel, and they all have the same resistance value, then the total load would be a third of the value of each speaker’s resistance. Here’s a formula to calculate parallel total resistance for two speakers: For more than two speakers, use the following formula:
