Every car audio installer, indeed, every automotive professional, will always recommend this first step: You want to do this in order to avoid any possibility of a short circuit. Remember that on many late-model vehicles, you will need a “radio code” in order to reactivate the radio. Amplifier Location Presuming that your car or truck has an existing stereo sound system and that you are interested in installing one or two amplifiers as an upgrade, the next step will be to decide the mounting location for the amp. Mount an amplifier less than three feet from the car’s radio or bolt it directly to the vehicle’s metal chassis, and you’ll hear a lot of annoying static, buzzing, and humming over your music. While mounting an amplifier in trunk or hatchback areas is usually a good idea, securing it in an upside-down position as seen here is not. To make sure heat can rise out of the amp and escape, make sure ventilated slats are facing up or to the side — not down. Amplifiers have slotted cooling fins on their surface to release internal heat that builds up. Power amps can get quite hot to the touch. When you select a location, make sure the cooling fins have plenty of space around them to dissipate heat which will radiate upward.
Sources Why you should trust me I wrote my first review of a subwoofer in ; since then, I have, to the best of my knowledge, reviewed more home audio subwoofers than anyone in the world. In my work for the above publications, I have conducted at least seven multiple-listener subwoofer comparison tests, so I have not only my own impressions to guide me, but also the impressions of other listeners, too.
This page on my website provides a more extensive list of my audio credentials. I play occasional gigs and attend workshops and weekly jam sessions, and I have heard many drummers and other bass players at close range, so I have a solid familiarity with what bass is supposed to sound like in music. A subwoofer is a speaker specifically designed to reproduce bass the deep sounds like the low notes on a pipe organ. You add it to an existing set of usually small speakers to give your system more bass and, potentially, a higher maximum volume.
Jan 26, · Now I have an old subwoofer lying around I also want to connect, but im not sure which would be the best method to connect it. I tried connecting it through the paradigm, using the paradigms output, but then my spare sub just didnt kick out as much bass as it would if it was connected directly to the amp.
How to Wire an Amp to a Sub and Head Unit A sub woofer or two in a vehicle can make the world of difference in listening to music. It is very important to match the RMS of your subs to your amp. You want an amp more powerful than your sub, because you don’t want your sub to clip. Clipping is the number one reason of bass distortion. Steps 1 Gather your equipment Amp, Subs, Stereo, and wiring.
If you’re using an after market head unit, go to an electronics store’s stereo department and ask for a wiring harness from your car to the after market head unit. If you have a Chevy and a Sony stereo go to them and tell them you need a Chevy to Sony wiring harness, they will ask you the year of the vehicle and then go pick it off the shelf, these are usually by the install department behind the counter. Figure out where you’re going to place the amp, put the beginning of your power red wire there and give it about a foot of wire extra, then begin to hide and run the power wire to under the hood.
Run the power wire through the firewall. If you need to drill a hole in the fire wall, be careful not to hit anything on the other side and be sure the drilled hole will not cut through your power line.
The Best TV
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.
Oct 06, · Up for one amp, down for the other amp. one A/V, and I would like to hook up both to one set of speakers. Do I need to use a Y-splitter or can I simply insert the bare wires from each receiver into the speaker terminals?. (its a whole house 16 channel amp), he put a power resistor across one side of the relay. That way the first amp.
June 20, Without being facetious, why? Do you use different amps for different purposes depending on the input? Do you have a different set of speakers connected to each amp, or do you use the same speakers, connecting and reconnecting them as required? Or, can you connect the same speakers to different amps simultaneously? Sometimes people switch amplifiers because there are trade offs in the sound of each so they use one with certain music another with other music.
Primarily though multiple amplifiers would be used in biamplifed or triamplified system. In a biamp system there is no passive crossover so the division of sound is done before the amplifiers with an electronic crossover this is the same as using a powered subwoofer with a surround system. The amp is connected directly to the individual speaker.
Why is connecting multiple speakers to one output bad?
An avid camper and erstwhile Boy Scout, I was amazed at how many things I could do with this well-made, pocket-size wonder. I used its tweezers to remove splinters and ticks, its scissors to cut thread, its can opener to prize open tins of baked beans, and its knife blade to whittle, occasionally cut myself, and generally wreak teenage mayhem.
As I grew older, I discovered that using specialized tools for a given job was generally easier, faster, and more pleasurable than using my Swiss Army knife’s utilities. Though I could cut a tent’s ground cloth with my knife’s scissors, a plain-Jane pair of Fiskars worked much better, an OXO can opener got me into those baked beans much faster than my Victorinox could, and even my Swiss Army knife blade didn’t stay as sharp or fit in my hand as well as a simple Buck knife.
Still, there was no doubt that my Swiss Army knife was a great tool and a good value, even if it was never the best tool for a specific task. To put it another way:
The wiring harness adapter creates a universal platform for connecting the aftermarket amplifier wiring that will connect to the powered subwoofer. 5 Plug the patch cables from the amp wiring kit into the free leads of the wiring harness adapter.
What is an ohm? How does a 2 ohm load effect an amp? How does a 1 ohm load effect an amp? Or 4 ohm load? The ohm load effects power output in amplifiers as well as sound quality. Subwoofers can measure 2 ohm, 4 ohm or 1 ohm. All speakers have a measurement of resistance, called impedance which is measured in ohms. Car stereo speakers are typically 4 ohm.
You will find car stereo subwoofers in a variety of configurations like single voice coil 2 ohm, dual voice coil 2 ohm, single voice coil 4 ohm, and dual voice coil 4 ohm. Dual voice coil means the subwoofer has two positives and two negatives, which give you the flexibility of wiring the subwoofer two different ways giving you two options for final impedance. These variations do not make one speaker more powerful than another despite what many consumers may think.
February 3, I have the AMP and am currently using it to power my 2 front speakers in my 7. Would the AMP be able to power the subwoofer in addition to my 2 front speakers? Also, which subwoofer do you recommend of the two noted?
Two 8 ohm speakers wired in parallel will have a net impedance of (8 divided by 2) 4 ohms. If you have three speakers, each at 8ohms, divide 8 by three to get a total impedance of ohms. If the speakers do not have a common impedance, you can use formula 1 for two speakers or formula 2 for more than two .
Next Audiophiles know that a stereo is not complete until you’ve added a subwoofer to your system. The subwoofer is a speaker specifically designed to give precise sound to low frequency audio, such as the bass [source: Whether in your car or your home theatre, a subwoofer is a must for a true and complete audio experience. Read the steps listed below and learn about how to connect a subwoofer to an amplifier. Turn the amplifier and the subwoofer so the backs are facing you.
You will be able to clearly and accurately see the labels on top of the outputs and plugs. This is the terminal used to connect the subwoofer to the amplifier. Connect the cable that was included with the subwoofer to the amplifier’s terminal. Alternatively, you can connect an RCA cable that can be purchased at any electronics store [source: Connect the other end of the cable to the terminal on the back of the subwoofer marked Line In [source: Insert an audio disc that has deep bass sounds and press play.
Human ears are the best devices for gauging whether your subwoofer is set up properly. Set the phase control on the amplifier to zero and the output to minimum.

Can I not adjust the phase on the soon to arrive FV15HP or my current sub or my minidsp to correct the issue you noted? I’m reading and learning but I don’t really really “get it” yet. My current sub is an ancient velodyne VA which is a 12″ front firing woofer facing forward and a 15″ down firing passive radiator; my graphs are showing -3db around 28 Hz from 75 db REW test sweep.
Is the passive radiator design considered sealed? I prolly should have got the F15HP if I had realized that.
Speaker Loads and Wiring An amp works best when driving a load with the same impedance as the amplifier’s “output impedance”. If they don’t match, there could be consequences: There are two ways you can connect two speakers. One way is called “series wiring” and the other is called “parallel wiring”.
How to Install a Subwoofer With Built in Amp by Jule Pamplin To create a truly powerful car audio system you need to have a wide ranging speaker set-up and the proper power to drive those speakers. Most vehicles are equipped with a series of door panel and rear deck speakers. Optional stereo systems often come with subwoofers and amplifiers. If your vehicle is not equipped with an upgraded audio system, you can install amps and subwoofers yourself. To save time and space a popular solution is a powered subwoofer.
A powered subwoofer is a sub that comes with a built-in amplifier. Powered subwoofers are easier to install and saves space in your trunk or rear cargo area. Disconnect the grounding cable and attach the ring terminal from the amplifier wiring kit. Loosen the bolt that holds the grounding cable to your vehicle’s negative battery lead with pliers or an adjustable wrench.
Move the cable away from the lead. Remove the bolt from the positive lead and connect the ring terminal. Replace the bolt and remove the fuse from the fuse holder of the ring terminal.
I’ve had friends run Kove 12″s, 4 doors and 2 tweeters off a 5 channel amp before. I doubt it got the sub to it’s RMS rating, but it sounded pretty good and got the job done, I just wouldn’t recommend it like that. I want to amp my tweeters and 6X9’s and my sub, different amps for the subs and speakers I don’t understand how you do it because the speakers have to be hooked up to the head unit right?? The power lead connects from the amp positive terminal to your battery – you will have to route the leads under your carpet.
The earth goes from your amp to a suitable earth i.

It also has a 5V output, which a few of you might be interested in. This is a perfect supply for the kit. Connecting a 90 ohm power resistor in series with a. Because this unit is external, no AC enters your chassis. This means less potential for humm. Also, because the supply is outside, there are fewer size constraints on selecting your chassis. Finally, the fact that it’s prebuilt gets you up-and running in a shorter amount of time. A link discussing the KIT supply also in stock.
An example of a balanced input schematic is shown on Luc Henderieckx’s page: Power Supply and Balanced Input jpg. There are no custom printed circuit boards. They are not necessary to make typical applications of the kit work. The board I’m referring to looks like a solderless breadboard, to make the transfer easier.
