How to Wire a Dual 4 Ohm Subwoofer in Parallel for a 2 Ohm Load

The amplifier within a car stereo system plays an important role as it boosts the signal from the radio, CD player, or other inputs, and powers the vehicle’s speakers. While the quality of factory-installed amplifiers has improved, there are many cases in which installing an external car amplifier , or power amp, is necessary or desirable. Head space in dashboards is limited, so the amplifier that comes with a car stereo is small, usually offering around 10 watts per channel. Drivers who upgrade their sound system by adding a subwoofer or upgrading speakers often need to install an external amp to power these improvements. An aftermarket amp can also improve sound quality by providing a clean power source. Choosing, buying, and installing a car amplifier is not always easy. Amps come in many configurations, from mono-channel amps good for a single-speaker or sub, to five-channel amps designed to power a complex sound system.

Amplifiers that are 2 ohms stable produce more power resulting in more volume. This amp can comfortably power speakers or subwoofers with all channel s being used at a load of 2 ohms. We have developed a specific linear circuitry that further reduces distortion while increasing both sound quality and power output. High and Low Level Inputs An amplifier with both high-level and low-level inputs provides flexibility by allowing you to build an audio system using virtually any standard factory or aftermarket source unit.

High-level speaker level inputs accept the signal from the speakers, while low-level RCA inputs accept the signal from the pre-amp outputs of the source unit. Protection If the amplifier gets too hot, the thermal protection circuit turns the amp off and allows the amp to cool down before turning it back on.

Common Car Stereo Problems, Symptoms and Solutions: Aftermarket Stereos

Or do i need that tacotunes equalizer thing? In my head its like I also thought of I never use my Aux cable. I wouldnt need the car to play if the bed is playing too.. Sounds a bit complicated and I’m not sure it’s worth it.

This feature eliminates the need for a remote wire that connects to the back of an aftermarket deck to turn the amp on when the headunit turns on taco-tunes sells a harness for this as well but if you can find an amp with auto-on, that would be the best way to go.

Whether it’s an installation that might not have gone as planned, or a random problem that comes out of nowhere. Here is a list of your common car stereo problems, symptoms and solutions to help get your stereo up and running! Many Jeeps and Chevrolet systems have a data signal wire that carries a very low voltage signal that tells the OEM Head Unit when to turn on, however; it is not compatible with aftermarket units. If you have a voltage meter or a test light, test the ground black , constant 12v yellow , and accessory 12v red wires to make see if you have the correct voltage in the correct wires, as well as a good ground.

Constant will always be 12v, whether or not your car is on. Make sure to use your ground, as well as another ground like the frame or body of the car while testing your constant and accessory to test that you have a good ground. If you find that one of your power wires or ground wires are not correct, check your vehicle wire diagram and make sure you have the correct corresponding power and ground wires.

Cars use thicker cable due to the high amount of current being drawn from the battery lower voltage appliances tend to draw more current then higher voltage ones, it also helps reduce voltdrop. Someone has said that CCA is what you want to look for on a car battery this is incorrect as Cold Cranking Amps are for when the car is cold and you try to start the engine its designed for a very short duration while keeping a voltage of 12V, the actual battery usage you need to look at is measure in Ah these are usually much smaller then the CCA and are the rating you can safety continuously draw from a car battery.

Note for the writer its a great article but i wouldn’t recommend soldering then crimping, solder is very soft and will become loose after a while your better off crimping stright on the copper. I have recently hooked up my Amplifier to a PCU. But I only used one black and one yellow wire of the PCU to power it.

Two of my other associates agreed with my assessment of his system compared to the system in my store with the Vivas and Super Eclipse.

I feel this information will be important to the owners of these superb amplifiers. There’s very little editing: I want to call attention to both you and owners of the Canary CA , a moderately inexpensive vis a vis very expensive premium B tubes way to kick up the performance of these amps. Having just brought another pair of them into my showroom, I decided to leave the stock Electro Harmonix B as is. For less money than a pair of KR B’s these amps take 2 pair each keep in mind , the changes were breathtaking.

Transients, soundstage, and articulation were noticeably improved. I thought your readers might be interested to know that, although these amps benefits from premium B tubes, these changes are a great cost effective compromise. Its power rating appears “modest” 22 watts, 90 watts peak , and it does not break any new sonic grounds, but the “good news” is that this amplifier can virtually equal most amplifiers we know of in most areas of music reproduction.

This means that it has much of the pure, natural, immediate and liquid qualities of the finest of the ultra low-power under 10 watt single-ended amplifiers, while still sounding as “gutsy”, dynamic, and controlled as many more powerfully rated amps.

I had the pleasure of meeting him the first time about five years ago when I toured the Focal factory, with my friend John Bevier. After business hours, he was. Every time I saw him at a hifi show, no matter how busy, he always took the time to come over my way and give me a big hug. Even though I am a relative newcomer to this industry, he always inquired to how I was doing. September 18, Cleaning the closets a bit today, I ran across the first issue of The Absolute Sound.

It is an opportunity for us to reflect on the language and ideas that represented each year. So, take a stroll down memory lane to remember all of our past Word of the Year selections. Change It wasn’t trendy , funny, nor was it coined on Twitter , but we thought change told a real story about how our users defined Unlike in , change was no longer a campaign slogan. But, the term still held a lot of weight.

Here’s an excerpt from our Word of the Year announcement in The national debate can arguably be summarized by the question: In the past two years, has there been enough change? Has there been too much?

A History: ’s Word of the Year

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.

Next, I connected them to the main speakers, where it competed with the Golden Tube B mono amplifiers above , which are highly modified.

I want to hook up one DVC sub 2x4ohms to a mono mtx thunder d amp and I want to run a 2ohm load. Amp’s manual says nothing about bridging http: Will I need to add another set of speaker terminals on my sub enclosure to do that? Will I need to add another set of speaker terminals on my sub enclosure to do that? Is there an easier way? BUT, the amp has 2 sets of speaker outs. Don’t I need to do anything with them as in connect the positive of one channel to the negative on the other channel and use the un-connected set of positive and negative to the box?

Does it matter which channel on the amp I use to connect to the box? How do I bridge a Class D mono amplifier? It isn’t possible to bridge any mono-block Class D It isn’t possible to bridge any mono-block Class D amplifiers. All of these models are Mono amplifiers, meaning they only have one channel. Then why does a single channel amp have two terminals L and R?

Austin, Speakers and subwoofers for home use are not made to withstand the rigors of constant vibration, high input volume, large temperature changes, moisture, and dirt that speakers designed for mobile use are.

Only time will tell if the latest wave of change Americans voted for in the midterm elections will result in a negative or positive outcome.

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.
