Vibe 17 Test conditions: This generally causes no problem because the increase in current is still below the current normally drawn by other amplifiers. There is at least one very popular brand of amplifier that draws as much as ma of current when the amplifier fails. This is enough to damage the remote output switching transistor in the head unit if the fuse is missing or is of the wrong value. A relay in the remote circuit will completely eliminate the possibility of damaging the head unit in this situation. The input circuit sometimes called the ‘front end’ generally employs a noise cancelling circuit which compares the signal on the center conductor the audio signal to the signal on the RCA shield which generally has little or no signal and is only used as a reference and amplifies the difference between the two. The input impedance is the impedance that the signal source ‘sees’ from the center conductor to the shield on an unbalanced input circuit.
I am not a HiFi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer. All the schematic diagrams that I could find seemed to involve lots of hard-to-find components or you had to use it together with a pre-amplifier or some other amplifier stage. It was always something that made me hesitate. But recently I found this awesome little chip called TEA !
You only need a few capacitors to make a decent stereo amplifier out of it.
Sep 28, · 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.
In some ways, thick, high-end wire can present MORE of a problem than the conventional skinnier stuff. More on that later. For the purposes of discussion we will use the term “amp” short for amplifier to refer to any receiver, integrated amp or power amp. This sheet is intended for solid state, transistorized sets. We’ll leave tubes out of this particular discussion. It is absolutely crucial that you use extra care in hooking up any solid state transistorized amp. The first rule is to make sure the amp is turned off before connecting the speakers.
Next make sure your wires are long enough to reach the speakers in one piece – rather than splicing numerous pieces together. When connecting the wire to the amp and speaker, make sure you have the proper “connectors” on the wire to mate with their respective terminals. There are many types of plugs, jacks etc. We can either supply you with these connectors or send you to a place that has them. Often connector plugs are not needed and simply “tinning” the stranded wire with solder is adequate.
My car speakers are making a crackling noise
Both the theory and practical points on how to connect 2 speakers are discussed. Connecting 2 speakers in parallel or series to your amplifier is useful when: If you need to turn each speaker on or off individually or have separate volume controls, you may need a speaker selector switch. Many people get confused when we talk about a stereo amplifier. A stereo amp simply has two amplifiers built into the one box.

Amps serve to increase the power to the car radio and speakers, all while improving the quality of the audio.
Our car-stereo amps are constructed to deliver in every aspect with the folks that enjoy loud and refined sound in mind. Kicker offers five series of car amplifiers: The IQ amplifiers combine power and control to deliver great sound. The KX amps boast a more sleek design, along with potent features to pump out up 2, watts of power.
The CX series benefits from an optimized circuit layout and the highest-grade internal components available to obtain massive power levels. DX amplifiers comes loaded with Fail-Safe Integration Technology circuitry to deliver superior clarity and wiring flexibility, which allows you to wire the amp directly to your factory radio without any converters or special plugs.
The PX amps, with as much as watts, deliver incredible power from a small footprint.
Rated at 1, watts, you can comfortably get consistent watts of RMS power going directly to your subwoofer. With this Pioneer amp, you can adjust the subwoofer accordingly from at little as 40 Hz to as much as Hz. The newer amps including this one have a wired bass control module, allowing you to turn the bass level up or down without having to physically go to the amp itself and do it. The speaker level inputs allow you to connect your OEM headunit without having to buy add-on adapters or anything that does not have RCA-inputs.
Blinking LED lights are popular in nightclubs and with car stereo enthusiasts who want to synchronize a light show with their music. Available in wall-mounted strips or flexible cables, the LEDs connect to your speakers’ positive and negative terminals.
I added a bunch of extra capacitors to reduce the noise, and I added a bass boost control as well to make it sound even better. Download my parts list for the LM amplifier with bass boost circuit to see which components to use for good sound quality. The chip has options for gain control and bass boost, and it can also be turned into an oscillator capable of outputting sine waves or square waves. There are three varieties of the LM , each with different output power ratings: The datasheet has graphs that will tell you.
I used a 9V battery for the power supply and it works great, but you can go down to 4V or up to 12V. Operational amplifiers have a basic task.

Unsubscribe The car amplifier doesn’t provide a signal to the sub I have the most perplexing of issues at hand, and I don’t know where else to turn to but here. My sister’s car — namely, the car’s sub amplifier — is giving me all sorts of sass. I’m trying to diagnose it from a world away she’s in Tennessee, I’m in California and it just does not want to work properly.
May 09, · My other suggestion is a technique that is commonly used in amplifiers, but the amplifier needs to be designed specifically to work that way. I forgot to add that paralleling two amps, even if it did no harm, would not be any louder than a single amp .
I drove to work about month ago and it was hit by a tree and sustained quite a bit of damage. The body shop came and got it a week ago and said they thought it may be totaled which is exactly what I was hoping for. However, when the insurance adjuster called me he said it was not a total loss as the damage was about 14k and will take about 6 weeks to fix.
I was disappointed cause I know this truck will not be worth near as much if I try to trade it in for another or sell it privately. I called the body shop and asked if there could be more damage to raise the cost up like frame damage and they said no frame damage but maybe pillar damage so I asked them if they would do the tear down and he said he would have the shop owner call me. He said Progressive said salvage value for my truck is 4K which I know not to be true. The shop owner offered to sell truck for me which he thought he could get k for it and I could take the insurance money and get another truck but I would be short about 10k but it may not be a bad option.
I can file diminished value against Progressive as Washington state is one of the few states that allows filing against your own carrier. Has anyone ever claimed diminished value?
Information On Installing A Car DVD Player – How To Install A Mobile DVD Player In A Car
Car Audio Black Friday Sales! Now it is time for one of the most critical aspects of the installation: Fine tuning your system tweaking. Tweaking is a very long process, especially if you have many channels of amplification. Take your time to get everything set for optimum performance. Professionals take days, even weeks to set a system up.
A: The amplifier sends an Amplifier Present signal to the radio. The radio sends low-level audio signals to the amp, which in turn amplifies this signal and sends it to the rear speakers. If there is no amplifier, the rear speakers are connected directly to the radio and the radio sends speaker level audio signals.

Importance Correctly setting a sound system’s gain structure is one of the most important contributors to creating an excellent sounding system. Conversely, an improperly set gain structure is one of the leading contributors to bad sounding systems.
The cost of the system is secondary to proper setup. The most expensive system set wrong never performs up to the level of a correctly set inexpensive system. Setting all the various level controls is not difficult; however, it remains a very misunderstood topic. The key to setting level controls lies in the simple understanding of what you are trying to do. A few minutes spent in mastering this concept makes most set-ups intuitive. A little common sense goes a long way in gain setting.
A dozen possible procedures exist for correctly setting the gain structure of any system. What follows is but one of these, and is meant to demonstrate the principles involved.
