How do you hook up an amp to home theater receiver

Modifications How to add extra car speakers The standard twin-speaker car stereo system has one obvious drawback. If you mount the speakers on the rear shelf, to hear the sound clearly you often have to turn up the volume to a level that is too loud for the rear seat passengers. Choosing speakers Choosing speakers Whether you are fitting four new speakers, or just adding an extra pair to your existing system, the choice is vast. Below are some old speakers and fader controls from Pioneer. A TS-VX is a surface-mounted wedge-type rear speaker. B TS-R mounts into the rear parcel shelf.

Using a Speaker Selector Switch for Whole Home Audio

That meant that we were looking to limit our energy usage as much as possible, and being able to charge the battery while driving from the alternator as well as when parked for a few days solar. Sprinter-source had a couple of examples for auxiliary battery installations, and we ended up following broken granites guide almost exactly sprinter-source. We bought a DieHard marine battery with amp-hours at Sears tip: The battery, ACR automatic charging relay, Amazon and maxi fuse block Amazon are all installed below the passenger seat, and we used 4-gauge wire from the local auto parts store for all the connections.

Solar charge controller and fuse block Amazon for our appliances are mounted below the drivers seat facing backwards. Not expensive, bright, and most importantly, they run on 12V so you can simply connect them to your car battery.

Look at it this way: if you hook up a bulb with resistance R to a battery with voltage V 1 then the power consumed is P 1 = V 1 2 /R. Hook it up to a different battery with voltage V .

These switches allow you to route a single audio source and sometimes more than one through a switching system that distributes the audio to various speakers or speaker pairs throughout the home. In this way you can choose, or select, which areas of the home you want to have audio. While simplistic, there are things you want to take into account when using these devices so that you use them properly and also maximize the way you distribute audio to various speakers in your particular application.

Typically, a speaker selector switch is placed after an amplifier or AV receiver, so that it can take a source—be it a radio, iPod or other streaming music source—and pass that on to speakers throughout your house. These are typically passive devices intended for use with already-amplified speaker-level signals. Options and Controls Speaker selector switches can range from handling two pairs of speakers all the way up to 8 pairs of speakers or more, but they all work in basically the same way.

Most people ask if I can explain the RV electrical system in simple to understand terms. The electrical system in your RV can seem complex and confusing until you have a basic understanding of how it works. Your RV actually has three separate electrical systems.

In a car or pick-up your wiring and cigarette hook up is usually only rated at around 6 amps. For over 50w you should run power directly to the battery HOT & GROUND post. Always put an in-line fuse on the wire at the HOT battery post.

These are generally heat producing devices such as light bulbs, toasters and coffee makers. Starting can be as simple as flipping a switch as in a hair dryer or power drill. Listen closely to your refrigerator and you will hear it cycle on periodically as its fan, compressor or defrost cycle starts. To continuously run the unit, you need approximately watts.

However when the compressor kicks in, it requires a the additional surge watts. As it settles into its running watt requirement of , the difference of watts can then be used to power something else. If you have a low to mid watt generator up to running watts you may opt to run your refrigerator most of the time and and rely on it keeping itself cold with the doors closed, then unplug and switch the power to other needs.

How do I hook up a subwoofer and amp in my car

The only big difference between them normally is the ohm. Car speakers are normally 4ohm. Home speakers are normally 8ohm. But there are many home speakers that are 4ohm and many car speakers that are 8ohm or 2ohm and even 1ohm. Jl audio makes 3ohm speakers. There are many home drivers that would sound great in a car and many car drivers that would work in your house.

To connect your iPhone, iPad or iPod to your home stereo you just need a mm to RCA cable like this cable above. The two RCA connectors plug into the back of your stereo and the mm plugs into the headphone jack of your iPhone.

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. I also have 2 sub woofers output in the back of my home receiver. But you can just use a y splitter like you did. My subs that go to my car audio amp are dual voice coil 4 ohms basically ran down to 1 ohm with my amp being 1 ohm stable. I hear people saying that you cannot get a car audio system to sound good in a house but I beg the differ.

Electric car charging: the basics you need to know (updated)

This is normally the distance from the speaker to the last row of seats in the room. Type in feet or metres the metres is calculated from the feet — if feet is used. This is how loud you want the sound to be at the distance specified. Some general levels are: This is not an indicator of how sensitive the main human speaker is, but rather a measurement of the sensitivity of the loudspeaker.

If you have a stock or aftermarket system and plan to add a subwoofer and amplifier, you’ll have lots of options for small subwoofer systems that don’t take up much cargo space.

You can use an inverter to supply power to devices such as televisions, microwaves, computers or power tools. They provide power in areas where you normally would not have access to standard Volts AC from the power grid ex: You simply connect the inverter to a 12 volt battery and plug your device into the inverter. This is a great solution for having an easy to use, portable power supply.

There are many kinds of inverters and many different sources from which they convert power. Some smaller 12 volt inverters convert power from your car battery through the cigarette lighter port on the dashboard. With other kinds of inverters it is important to match them with batteries of the proper type and size. It is important to be discriminating in the purchasing process.

If you are using a small inverter with an automotive battery this will work sufficiently. Most car batteries will supply enough power for 30 to 60 minutes before they need to be recharged.

How to hook up speakers correctly for proper impedance

The tech world has finally coalesced around a charging standard, after years of proprietary adapters and ugly wall-wart power supplies. Ten to 15 years ago, you always had to make sure you had the correct power supply for each of your gadgets. Not all USB chargers, connectors, and cables are born equal. Sometimes, one USB socket on a laptop is seemingly more powerful than the other. In almost every case, your PC is the host, and your smartphone, tablet, or camera is the device.

Okay, now the numbers.

Amp Gauge Wiring 1) Always disconnect the ground lead from the vehicle battery before wiring any gauge. The Amp gauge was designed to be wired in SERIES with the vehicles electrical system. In order to damage to other electrical components, or damage to your car. 2. 1 / 8 ” Amp Gauge. O G L S I. Dash Light Power Dash Light Ground.

How do you hook up a 1 farad capacitor to your amp? Answer 1 You first have to determine which side of the cap is positive andwhich side is negative. You run a wire from the negative side tothe chassis and …for the positive side you run a cable from thebattery to the terminal and from the terminal to the amp. Be careful not to mix up positive and negative on the capbecause it could explode and cause damage. Answer 2 Because the capacitor is used to filter changes in supply voltageto the amp, the capacitor should be as close to the amp aspossible, and connected with heavy wiring.

The capacitor also actsas a huge reservoir to supply lots of current as the amp signalhits high levels. By providing plenty of current when it is needed,distortion in the sound is minimized. The key is lots of capacitance, as close to the amp as possible,and thick cables capable of carrying lots of current. Answer 3 Be very careful with that thing. The current output of a capacitoris the product of capacitance, in this case 1, and the change involtage with time.
