A bit of background I have 4 sealed 12″ subs, 3 of the 4 are DIY “car subs” and one is a paradigm sub I started with the Paradigm, then had an old beater car sub sitting around from about 20 years ago wired it in with a cheeseball HTIB plate amp and was immediately impressed with the better room response but not with the output.

How do I connect a set of four ohm speakers safely to an eight ohm system? There are many variables to consider when connecting 4 ohm speakers to your system. Please consider the following: Define your system Are you using a Receiver or separate power amp to drive your speakers? Most midfi Receivers may have problems adequately driving a 4 ohm load.
The Car Audio Help DVD catalog includes five different videos covering many areas of car audio installation and custom fabrication. Topics range from basic system installation (head units, amplifiers, speakers, etc.) and mobile security (car alarms and remote start) .
These mistakes can range from simple problematic issues to things that could quickly lead to premature device failure. Let me quickly explain why. Every cable has inherent resistance. The thinner the cable, the more resistance the cable will have. There are other factors as well, but this is the big one. The more resistance a cable has, the more it will affect the frequency response which is possible at the end of the cable run. The reason this is related is because the load the amplifier has to deal with when driving a pair of speakers, changes with frequency.
So if you add more resistance with cables that are too thin, you can actually change the sound—particularly at higher frequencies.
How many speakers can I add to my receiver/amp?
Speakers Clint DeBoer Speaker Impedance Rating Explained That speaker impedance rating on your towers and bookshelf speakers is held up as a mystery—something strange and mystic, yet dangerous. The bottom line is that people are confused about speaker impedance. Speaker Impedance Defined I think the easiest way to define speaker impedance is to say that it is the resistance any speaker gives to the current and voltage being applied to it.
The only reason for the ability to connect large wire to say a w amp from what I can see is convenience. You don’t want to have to run multiple wires to connect to more than one amp. A watt amp that only runs at 25a should only require 12g wire.
Share on Facebook There are two ways to wire four speakers to a two channel amplifier: Which one to choose depends on both the speakers and the amplifier, specifically their impedance levels and limits. Wiring speakers in series raises the impedance delivered to the amplifier, while wiring them in parallel lowers it. Amplifiers have both a minimum and a maximum level of impedance and it is important to stay within these limits. As many speakers as your amplifier can handle can be wired together.
Determining Which Method to Use Step Determine the minimum and maximum impedance levels of the amplifier—measured in ohms—by referring to its manual. Step Determine the impedance of the speakers by reading the label on the speaker itself or by checking their manual.
Connecting 4-ohm Speakers to an 8-ohm Receiver
The most basic way to wire marine speakers to an amplifier is to connect one speaker to each of the available channels. But there are other options to consider. Most external amplifiers can power more than one speaker per channel. For example, a 4 channel amplifier may be able to power up to 8 speakers. In fact, if you wire it correctly, you will be able to pull up to twice as much power out of the amp.
First, you need to make sure your amplifier can be safely set up this way.
May 08, · The inuke amps don’t accept RCA inputs, you will need to get a RCA to XLR cable and an Speakon connector coming OUT from the amp to hook up to your sub. lemonslush is offline Quote.
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.
Share on Facebook You’ve just purchased watt speakers capable of a gust-busting 91 decibels, backed by a watt four-channel amplifier. The only problem here is that you’re a bit lacking in the wiring department and want to make sure you’ve correctly put together these monster noise machines all for the sake of blowing your neighbors out of their lounge chairs.
Hooking up speakers to an amp is simple. Speaker wire comes in various gauges, lengths, resistance and capacities. Step Measure the distance from the amplifier to the speakers.
Depending on the type of connectors used for the amp’s outputs and the speakers’ inputs, the speaker cables can be terminated with banana plugs, spade lugs, or simply bare wire. If the cables have spade lugs, make sure they fit on the amp’s binding posts—some spade .
Installing Multiple Amplifiers There seems to be some confusion when it comes to installing more than one amplifier. Should you use one power wire or multiple wires? Do you ground everything to the same point? How do you split the low level signal? Let me share my thoughts on the topic of installing multiple amplifiers. Power Wire With more amplifiers you’re going to need either more wire or larger wire.
Personally, I prefer to run one new wire that is large enough for all of the amplifiers and any planned upgrades. The price difference between two wire gauges i. I would run one wire for several other reasons as well. First, it’s usually cheaper than two wires in terms of material and labor costs. Since there is only one wire you only need one ring terminal at the battery post and only one fuse holder for the audio system.
When using one large wire for multiple amplifiers you’ll need a way to split the power wire into smaller wires for each component. I prefer to use a regular distribution block, not the fused type. They’re less expensive and there’s no need for the extra fuses when there is already a fuse holder near the battery that protects the main power wire you’ll have to install this fuse holder.

When you hook up more than one speaker to an amp, there are two ways they can be arranged: in series, or in parallel. Series means chaining the cabinets together one to the next. Parallel means sending one output of the bass amp head to one cabinet and a .
One thing I learned pretty early in life is that speakers are not meant to be wired together in a haphazard manner. In fact, whenever you plan to connect more than two speakers to a two-channel amplifier — or more than four speakers to a four-channel amp — there are a few things to consider, not the least of which is the amps ability to handle low-impedance loads.
Ignoring the basics is like playing Russian roulette with your amplifier: If youre lucky, itll drive the speakers without incident; if youre not, the amp will fry. The great thing about a multiple-speaker hookup is that once you master only two basic wiring procedures — “series” and “parallel” — the world is yours to conquer. When you know how many speakers youre going to use and the impedance driving capability of your amplifier, youll be able to select a wiring scheme that will deliver the best sonic and electrical results.
In some cases, it may not be one procedure or the other but a combination of the two that works best.
Do you recommend hooking up 4 speakers in a two channel stereo?
How to install an Amplifier: Disconnect the battery terminals: Run the power cable from the battery to the location of the amp or distribution block. To read more about running wires, click here If you run it through any sort of sheet metal, be sure to protect the power cable with a rubber grommet, or some other protective device.
Be sure you have plenty of slack at both ends of the cable.
Connect each speaker’s woofer and tweeter (+/-) terminals to the corresponding OUTPUT terminals on the crossover. Now connect the amp’s output terminals to the INPUT on each of the crossovers.
I know that by mixing series and parallel you can keep the total load within an amp’s happy range; that’s what they do in some multi-driver cabs. Say your amp wants an 8 ohm load. You have 8 4 ohm cabs. If you run two groups of four in series 16 ohms each and put them in parallel, the total load would be 8 ohms. Your amp is happy. I don’t know, I’m asking you guys if it’s dangerous.
IIRC, most amps run constant voltage and vary the current to keep the output voltage the same. Even if the load is 8 ohms total, I think it would try to put out a massive amount of current to keep the voltage across all those speakers the same. Or it would just divide the current put out between all the cabs? This is all just hypothetical, something that popped in my mind one day. BogeyBass Sep 14, you can run as many speakers you want as long as the total impedance does not go below the minimum rating of the amp.
Now a 4×10 at 4ohms has much more sensitivity so you might only need 45 watts to reach the same SPL level of dB. But not mad about it.
Tech Tip: Wattage, Speaker Efficiency, and Amplifier “Loudness”
How do you hook up an amp? Make sure that the power wire and aux cable are on opposite sides of the vehicle for less distortion and interference. MORE What is the difference between a 2 channel and 4 channel amp?
On the back of the mixer, connect the aux 1 send connector to the graphic equalizer (if any) used for the monitor speakers, and connect the graphic equalizer output to the monitor power amp input. If you’re not using a graphic EQ with the monitor loudspeakers, connect the aux 1 send to the monitor power amp .
Installing a 70 Volt Sound Distribution System: Here is how you connect a 70 volt sound distribution system. For a more detailed drawing click here 1 Connect your speaker wiring to the common and 70 volt output terminals on the distribution amplifier. All of the speakers need to connect in parallel. They can be either “home run” individually back to the amplifier, or “daisy chained” from one to another.
You can of course use a combination of both. The important thing is that the inputs to the volume controls or primary of each transformer if you are not using volume controls are in parallel with each other. Selecting the Right Components: Selecting the right Transformer taps: For a ceiling or wall mount speaker such as the ones described above, you shouldn’t require more than 10 watts to produce more than enough sound.
If you are not using an attenuator, you can feed sound to the speaker and experiment using different 70 volt wires 10w, 5w, 2. It is better of course to use an attenuator volume control and adjust the volume with that. If you do, you should connect the system as shown above, turn the attenuator to full volume, and choose the transformer tap which gives you the most volume you could want.

How Many Speakers can I put on an 8 ohm amp? April 14th, by Roemtech The question arises: How many speakers can be put on an 8 ohm amp? The answer is, as many as you want, theoretically speaking. You purchase eight of the finest ceiling speakers you can find otherwise known as the SP N.
Apr 16, · C: Attach the speaker wires to the terminals You have many options for this, google how to connect your wires and the amplifier or read the manual that is provided. You will wire differently based on amount of speakers and whether you want to do series of parallel. Wiring can also change the amount of Ohms that you are drawing.
How to Connect a Car Stereo Line Out Converter by Travis Corkery Remember the days when we hooked stereo systems up with stripped-bare and twisted wires stuck into little spring-loaded clamps? At least in the aftermarket and consumer audio world, that method has long since been replaced by coupling with plug-in RCA jacks.
Though RCA jacks are great for foolproof installation of audio components like amplifiers, almost all cars still use old-school single wires leading from the stereo head unit to the speakers. Not to worry, though; a simple line-out converter will get your system banging away pretty quickly, provided you’re willing to strip a few wires first.
Installing a Line Output Converter 1 Locate the wires running from the head-unit or factory amplifier to the speakers. In most cases you’ll access these wires behind the head unit. Attach the left channel of the L. Plug in some RCA cables to the L.
