How to hook up a car sub in a home theater


Crap somewhere else, we have heard your opinion. This thread is about what people have found to be true. If you think wire matters, but disagree with another poster’s preference or findings, politely say that your experience was different, and state what YOU found to be true. This thread has no right or wrong. That goes two ways. I’m gathering data on some upcoming modification projects, many of which involve upgrading the internal wire of some of my components and speakers. What I am noticing is that there are a lot of very exotic offerings out there, but not very many reviews by users who have actually given these products a shot. In particular, I am interested in any feedback on what wire people have tried, and what their results were. There are lots of testimonies about Cardas and Vampire.

How to wire amp with dash speakers?

If you are new to the concept of multi-way DSP loudspeakers, please read the overview app note Digital Crossovers Basics first. Check out this app note for more details. All of the above options can also be used to generate a subwoofer output signal summed from the left and right input signals, for a two-way-plus-sub or 3-way-plus-sub configuration.

The crossover adjustment screen in an Onkyo A/V receiver. Your crossover should be set no lower than the lowest manufacturers’ rated speaker response at +/- 3dB. You can find this in your users’ manual or on the manufacturers’ website.

I have not selected the amp yet, but was leaning towards: My dash and front door speakers are not a component set. Is it possible to make them a set if I get an active crossover? So I guess my choices are: Questions for option 2. If dash and fronts are one 2 channels, and say amp does 50w, does that mean the 50w gets split between the 4 speakers 2 dash and 2 front doors?

If this is the case, it seems I would not be getting the most out of my front doors if they are good up to say w rms But if the dash speakers were left just to the HU, all 50w would go to front doors? It has built-in support for high-level input which I am using currently.

How To Properly Hook Up Speakers to Amps

If not, click the link to take a peek, or visit our YouTube channel to find it and other great videos. These days, most people will utilize an auto-calibration of some sort, i. However, some entry level and older equipment will require manual setup. Audyssey’s standard auto-setup microphone. For best results, the microphone should be placed on a tripod in the main seating location, away from any surfaces, and you should step out of the room while the system is running.

There are SPL meter applications that you can download for a smartphone, and these will work, but they will likely be much less accurate than consumer-level SPL meter, like the Galaxy Audio CM , especially with subwoofers.

So you’ve taken the leap and opted for separates, and now you’re wondering how to set up the power amp properly with you’re A/V preamp/processor. Relax, it’s not difficult at all. There are two types of connections on any power amp inputs that accept line-level signals from the preamp/processor and outputs that send the amplified signal to the speakers.

I have a much better understanding of ohm cooking. I have two combo amps. One is a Fender Superchamp X2. The one speaker out jack that the internal speaker is connected to says Minimum 8 ohms. The other amp is a Vox AC10 with a speaker out jack of 16 ohm. I found the Bugera TS On the back it has a 4ohm mono jack and a 16ohm mono jack. I know the Vox will work best through the 16 ohm mono jack. I think the Fender would work fine going to one of the jacks with the stereo switch engaged knowing that the output would only come through one of the speakers.

I think… Could I reasonably connect the Minimum 8 ohm out from the Fender to one of the mono 4 or 16 ohm jacks. The article intimated that it would be ok. Which would be better and why? Also, you mentioned several times in comments that folks should be careful or to take it easy when trying mismatched options.

How to Connect a Crossover to 2 Amplifiers

The effect that room reflections have for different crossovers. The parameters provided by speaker manufacturers are not all that reliable. Good test equipment is not cheap, but it is a good use of your speaker-building budget.

you got a amplifier, 5 channels powered and a subwoofer signal(no amp) i bet you got a crossover in the sobwoofer signal path, just fiddle around in the menus of your amp and look.

Class AB amps combine the good points of class A and B amps. They have the improved efficiency of class B amps and distortion performance that is a lot closer to that of a class A amp. With such amplifiers, distortion is worst when the signal is low, and generally lowest when the signal is just reaching the point of clipping.

Class AB amps like class B use pairs of transistors, both of them being biased slightly ON so that the crossover distortion associated with Class B amps is largely eliminated. Class C amps are never used for audio circuits. They are commonly used in RF circuits. Class C amplifiers operate the output transistor in a state that results in tremendous distortion it would be totally unsuitable for audio reproduction.

Integrated amplifier and subwoofer

They filter the audio signal by frequency and direct it to the best amp and speaker in the system for maximum audio clarity. While passive crossovers are installed between the speaker and amp, and may lead to volume loss and be hard to adjust, active crossovers filter the line signal from the stereo, allowing for a better-quality sound and ease of adjustment. A typical application for a three-way active crossover is in a car audio system, but they can also be found in professional public announcement rigs and home theater systems.

If you do not plan to adjust it much after initial install, keeping the crossover behind the dash panels is a good option. If you wish to have easier access to the crossover’s controls, install the unit near your amplifiers under a seat or in your trunk.

Now the way to hook it up is the power wire coming from the front of your car goes to the + side of the c ap then another wire will go on the + side of the cap and go to the amp. The ground of.

In reality, a lot of these variables are mutually exclusive: If you want maximum power output, be prepared to pay more for the drivers and sacrifice some frequency response. Keep these things in mind as you read over the next sections. A Note on Speaker Selection Don’t skimp too much on the speakers: However you can have all of the above qualities without spending a fortune. A word to the wise: However, like most older things in the music industry, they have a “magic” premium attached to them, and hence you must pay more to get them.

Try and stay away from speakers with cloth accordion or treated paper surrounds for any designs other than open backed. The surround on these speakers can be a large source of air leaks in sealed enclosures, which results in lowered efficiency. Remember, each 3-dB increase in efficiency results in twice the apparent sound level at a given power input. Most speakers for instrument use are very high in the high 90’s, and some are over for the wattage they accept.

Open Back or infinite baffle Open back guitar cabinets are extremely easy to design, and typically require the least amount of construction material to manufacture. They have a very bright and full tone, and make great recording and live cabinets due to the fact that they have wonderful “room filling” properties.

DIY Hi-Fi: Class a Hybrid Headphone Amp

The term passive subwoofer correctly implies that there are no internal amplifiers and therefore external ones would need to be connected. Subwoofers are used primarily for low-frequency sounds and improving the bass quality of your speakers. The power ratings and the ohm load are a few of the things that you would need to consider in choosing an appropriate amplifier for your subwoofer.

Mar 24,  · Best Answer: Well I mounted a second amp just last week. to do that you need to connect the subs to the amp speakers output. Yes, you need a electronic crossover (3 way output recomended) to use the 2 outputs front and rear and 1lowpass output. This output is directly connected to your rear channel sub’s : Resolved.

Posted on July 26, by JoeDania83 We had a power surge that damaged the memory card or system and rendered the entire phone system useless. Luckily, we had the OfficeSafe backup system running. Allworx shipped a new unit to replace the damaged unit and rather than attempt to restore the older one which was booting to safe mode I just unwrapped and used the new one.

The frustrating part of this process is that when in safe mode, the Allworx units will only use the The issue there is, that if your OfficeSafe system resides on any other subnet, other than You cannot edit the network settings and you cannot enter alternative router information.

Subwoofer Crossover

Do I need crossover control? What is a crossover? A crossover is a very handy device that helps you take charge of the frequencies that are going to your various speakers. For example, it lets you send low frequencies through to your subwoofer or bass shaker amp, and it lets you send high frequencies to your other speakers. You probably don’t need a crossover if you have a subwoofer with built-in crossover control, like this one Crossovers can be purchased as separate devices, but be aware that often come built-in to your amps and receivers.

For sound boffins after more in-depth information, try the sites below:

Crossovers – Your amplifier may utilize an internal crossover. More than likely only subwoofers will be connected to the amp when used in Mono (Bridged) Mode. More than likely only subwoofers will be connected to the amp when used in Mono (Bridged) Mode.

How to Install a Car Amp Installing car audio amplifiers is one of the trickiest things a newbie car audio installer can attempt. Car amp installation requires that all sorts of panels be removed and that various wires be run all over the car. Installing car audio amplifiers is a step by step process which I have outlined here. If you have any questions please contact me by clicking here.

Please do not attempt a car amp installation if you are not comfortable with the process. Leave it to a professional. Now here are the steps on how to install a car amp. There is also a wiring diagram below. These directions assume you have already physically mounted your amplifier to a solid, non-conductive surface non-metal. If you have not purchased your power wiring be sure to read this article on choosing wire gauge for amplifiers.

How to connect my second amp up to my highs and do I need a crossover?

If you speakers have biwire terminals and you remove the jumpers then you can safely hook up an amp to each pair of terminals. This is called vertical amping bi-amping has an electric crossover feeding the amps. You will need a level control on at least on amp to adjust the amps to put out the same amount of power for the same input THX power amps are set this way with needing controls. Can’t hurt to try it. The improvement will not usually be power related but in some cases you will reduce the im distortion generated by the speakers feeding back emf into each other through the crossover.

That is why biwiring sometimes improves the sound.

Since i only have a two channel amp and these speakers arent sold as a component set with a pair of crossovers included im not sure how to go about wiring the speakers up. After research, ive gathered that wiring them in series or parallel off of the amplifier isnt a great idea.

This project was born out of a couple things. One was a need for an amp to drive some higher impedance headphones I had just bought. The Grado SR i headphone is great, by the way. Also, since I have began my freshman year at Boston University, and could not resist using the Singh Imagineering Lab- a workshop only for College of Engineering students that allows you to work on pretty much anything.

They also provide basic materials and components, as well as lathes, NC mills, soldering stations an electrical equipment, and a 3D printer. This is is just the tip of the ice burg though. Another reason for the project was an assignment from another class where I had to build something for my own enjoyment and benefit, but just had t keep a running journal on how the project went. This Instructable serves as my journal. Because of this, you will notice it is written as such, with running updates on aspects of the build and a more personal touch to the process than a simple step-by-step Instructable.

I chose a vacuum tube amplifier as opposed to sold state. The reasons to choose tubes are as follows:

Connecting subwoofer to a stereo-amplifier without pre-out for sub? (total beginner)

Can the repo men hook up your car with you in it? No, it’s illegal to ride in a towed vehicle. However, if you’regetting into the vehicle to prohibit the car from being towed, youcould find yourself in trouble with the law. Once the car is on arepo list, it’s no longer technically yours due to default onpayments.

Mar 10,  · Crossover and Speaker Settings in Relation to Bass Management Most, if not all AV amps and receivers now incorporate some form of bass management. In many instances this management allows a user to determine the point at which lower frequencies are sent to the speakers and subwoofer via crossover settings.

Relax, it’s not difficult at all. Let’s start with the inputs. A balanced connection typically uses XLR connectors, which are relatively large round connectors with three pins male or three holes female in a triangular formation as shown above. This same type of cable used with professional microphones. A balanced connection reduces the risk of induced noise from power cords, radio-frequency interference RFI , and electromagnetic interference EMI.

By the way, if you are going to the expense of a balanced system, make sure it is balanced throughout the amp and not just at the inputs. In a nutshell, here is how a balanced connection works. As I mentioned above, the two signal conductors carry the same signal, but one is out of phase with the other.

Any induced noise that is picked up along the cable will be at the same phase in both conductors. At the amp’s input, a differential amplifier recognizes and rejects any signal that is in phase in both conductors, leaving only the intended audio signal. Using balanced connections can help reduce the risk of ground loops, but only if each device’s ground is properly implemented. However, this is generally not recommended, because you lose any noise rejection and ground-loop isolation.
