Advice 1: How to connect a subwoofer with no output on the radio

On the road, many drivers and their passengers love to listen to music. For quality sound you need to install not only the radio and speakers, but the subwoofer is connected via the amplifier. However, very often the problem arises to connect, as not every radio has the connectors to connect the amplifier and subwoofer.
How to connect a subwoofer with no output on the radio
You will need
  • - soldering iron;
  • - instructions to receiver;
  • - wire pads;
  • - mount housings.
Instruction
1
Carefully read the instructions that came with your radio. If you lost it, go to the official website of the manufacturer of your head unit, find the model and download the manual for it.
2
Look on the manufacturer's website or in the instruction diagram and the Pinout of your radio. Then visit the forum dedicated to your model of radio. Probably someone before you tried to connect to this head unit, subwoofer or amplifier and shared the experience with their friends.
3
Remember that all intervention in the structure of the radio automatically deprive you of factory and shop warranty.
4
If you don't want to spend a lot of time and effort, it is possible the signal from radio apply directly to the speakers and the amplifier. However, there is one point. With regular connectors of the receiver is already amplified signal, so you need to install a special adapter.
5
Look on the forum the model of the adapter or ask the seller-adviser in shop of car audio. This adapter should provide a balancing force signal from the radio, with the power of the signal which passes through amplifier and subwoofer.
6
Remember that without connecting this adapter you risk burning out the line outputs of the radio.
7
Give your radio to feed separate outputs for a subwoofer and amplifier if you want to achieve maximum sound quality. It is not recommended to perform this procedure yourself as you can due to the lack of experience to ruin the scheme of a radio.
8
Connect to the connectors on the radio wire from the subwoofer and amplifier. Check out the care connection.
9
Route the leads so that they not only will not interfere with use of the car, but did not periklis any items or doors.
10
Carefully fasten the housings of the amplifier and the subwoofer. Make the first switch of the audio system and check that no parts are vibrated and did not produce any sounds.

Advice 2: How to connect speakers to receiver

To connect the speakers to the new receiver, no need to go to the car wash and spend a rather big amount of money. If you know anything about electrics,you can do it yourself.
How to connect speakers to receiver
You will need
  • To connect front speakers to the radio you will need 6 feet of flexible speaker cable 2x0,75 mm 2 rubber corrugations are 14mm in diameter with a rotation of the outputs by 90 degrees. Without turns, but then it will be necessary to carefully wrap the wires with insulation tape so they do not fray about the edges of the holes that you drill in the front doors, as the manufacturer is not provided in the doors, no wiring.
  • To connect the rear speakers, you will need 11 metres of speaker wire 2x0,75mm. Here can be applied not very flexible cable, suitable even for the ordinary, for home electrics brand of PVA. These wires will lie still during the entire period of operation, so they were not in danger.
Instruction
1
In the front door directly under the top hinge closer to the outer skin, make a hole with a diameter of 13mm. The second hole should be drilled at 100mm below when you open the door the wire was turned, not bent over. Then it will last a long time. Try how to house the wire in the door and mark with a marker the area of the wire passing through the corrugation, with a small margin.
2
At the point of exit from the body and the entrance of the door numatyta 5 layers of adhesive tape.
3
Wear corrugation and with the help of thin steel wire, tighten the wire in the door. Attention! In order not to damage the insulation necessary uglenite wire to make it easier went. Part of the wire that goes inside the body, cannot be laid under carpets – where the wire can easily be damaged, it must be tied with tape to the total transaction.
4
Output wire to the location where it will be installed radio. Leave a margin of 30...40 cm, for easy connection (if you need to remove the radio and put the other) and do the same work with the second front door.
5
The wiring for the rear speakers need to make one Board machine, for example, on the left, driver side. You should always strive to gather the wires in a harness.
6
Fold the wire in half penalty. One of the ends pull the meter and as such smithite the wires with insulation tape. Place bend cut pliers.
7
Now I have to put the resulting bundle of wires in the car. To lay better along the sill. For greater reliability, the section of harness that passes across the floor, can be tightened in plastic corrugation for electrical cables. Part of the harness that passes directly over the rear parcel shelf can be mounted with plastic clips.
8
The section of the harness at the front of the car also lift off the floor and attach with tape to the main wiring, and then output to the same place already plumbed for front speakers. Then to not look for where a wire is, the better their mark immediately. For example, "front right" or abbreviated English FR. The rest: front left FL, rear right RR, rear left - RL. Repeat with the rest of the acoustic wires the same. After that, if wires are the same color with or without stripes along the veins, and not in each pair to distinguish between conventional plus and minus, it is necessary to mark the negative lead.
9
When the wires are labeled, check the tester for short circuit between cores and in the absence thereof, they can be plugged in to the connector to put the radio in place.
10
Then check the speakers on compliance of the nominal resistance. Modern stereos to fit speakers with a coil resistance of 4 Ohms. If the device shows a resistance of 3.2-3.6 Ohm, can set up speakers in the prepared location and connect them to the speaker wiring. The main thing - not to reverse the polarity, otherwise the bass will not be enough. Please note that the speaker terminal is not in contact with metal parts of the machine.
11
When everything is connected, test the system.

Advice 3: How to connect the radio without line-out

The receiver is not equipped with line level outputs. It's a bit complicated to connect to amplifiers without high-amplitude input. Some firms-manufacturers of accessories for connecting amplifiers produce a special matching device adapters line. The use of this device considerably facilitates the connection of the amplifier to a radio without line-level outputs.
How to connect the radio without line-out
You will need
  • screwdriver, pliers, electrical tape, adapter line input.
Instruction
1
Getting started connecting the amplifier to a radio without line-level outputs, buy adapter line input for the amp. With it, you will be able to coordinate the output signal with a desired value input of the amplifier. These values from different manufacturers are very different. For example, the input voltage of the amplifiers SONY is 8V, and the same parameter amplifier Kenwood is 0.8 V.
2
Remove the radio and plug the adapter line input to the radio. To do this, connect the input wire adapter with wires acoustic receiver according to the connection diagram.
3
Set the value of the output voltage signal in accordance with the desired value for the amplifier. Try not to exceed this parameter, otherwise the volume control is stepped, with a sharp increase in the sound power for each increment of volume. In addition, the amplifier would be premature to go into full power mode, and when trying to add volume is to reboot and make a distorted wheezing sound. It is very harmful to speakers.
4
Attach the adapter to the line input to the cable harness with electrical tape. Make sure it fits behind the console. To reduce the likely bounce adapter body about the internal parts of the console, wrap it in 1 layer foam with a thickness of 10 mm. Foam, you can fix it with duct tape.
5
Plug the line cable into the outputs of the adapter with the marking line outputs.
6
Connect to amplifier power wires, a control wire turning the amplifier on and speaker wiring.
7
Connect to the amplifier linear wires in accordance with their marking.
8
Make a test on and check the correctness of the supplied signals. The sound of each speaker should correspond to its location. For example, with a knob Fader/balance move the sound to the right side. In this case, must sound only the right speaker, then turn the sound on front speaker. Now will only sound front right speaker. If all sounds where necessary, connections are made correctly.
9
Test the amplifier on the subject of the norm of the input signal. To do this, set the radio volume to 70% of maximum. Using the volume control on the amplifier, minimize the volume. If no distortion, then the input signal is correct.
10
Install the radio in place.
11
Adjust the maximum volume level of the amplifier using its built-in regulators. The volume knob on the radio needs to be set to 70% of the maximum value.

Advice 4: How to connect a subwoofer without the linear outputs

If you want to have in your car the music sounded not only loud, but also high quality, you will need an active subwoofer. He will immediately expand the range of sounds, add bass, and, of course, volume. If you decide to mount it yourself, be prepared to Tinker.
How to connect a subwoofer without the linear outputs
Instruction
1
Remove your radio. Immediately view, does it have line outputs. If there is, consider yourself lucky. You will have the opportunity to tune the pairing of the subwoofer with the speakers. If no line-level outputs, then connect it will be more difficult to configure have from the trunk, which is not very convenient. Typically active subwoofers installed in the trunk of the car. This is due to the size of the device. Place it in the cabin without the loss of usable area you will fail, so immediately focus on the trunk. Spend there a control wire from the radio, plus power and minus power make.
2
Take multi-strand power cable of suitable length. You will need to make a negative lead, respectively, to connect a subwoofer without the linear outputs. The cable section must be at least 6 square millimetres. You can buy it at any market. Locate the bolt that is bolted to the body.
3
Clean it from the paint that was good contact between the metals. Wrap around this bolt is a coil of power cable. Then tighten the bolt so that the cable is securely pressed. This is a very simple design and will be a power disadvantage, which will be used to connect a subwoofer.
4
Take another power wire at least 6 square millimetres. He will need to do the power plus. Route it through the interior to the trunk of a car. In the partition between the engine compartment and the cabin should be a small hole. If not, take a drill and drill.
5
Insert the cable into the hole, wearing it on the rubber grommet. It is needed in order to protect the cable insulation from abrasion. Connect it to the positive battery terminal. Take the plastic clips. With their help secure the wire along the entire length of contact. Embed the holder with the fuse in the power cable near the positive battery terminal.
6
In the absence of line-level outputs use high-amplitude inputs built-in amplifier. Connect the control cable to the subwoofer. Connector high-amplitude inputs connect to the speaker system. Do not forget to observe polarity. Move into the trunk signal and the trigger wire in the trunk connect to pads built-in amplifier.
7
Review the wiring diagram. In accordance with her perform all the switching. Then configure the sound. After the setup is finished, return the radio to its original place and secure the subwoofer.

Advice 5: How to connect subwoofer to receiver without amplifier

A subwoofer is a speaker system that reproduces sound in the frequency range from 20 to 120 Hz. To connect car subwoofer to receiver, does not need to go into an auto service center to do it by yourself.
How to connect subwoofer to receiver without amplifier
You will need
  • - linear wire;
  • - two power wires;
  • - capacitor;
  • - the fuse.
Instruction
1
To connect to receiver active subwoofer, look on the back of the car two inputs and using linear wire connect the inlet of the head unit to the input of the subwoofer. Now connect the power: to do this pull the power wire from the positive terminal of the battery to the subwoofer. "Negative" wire should connect the battery and the subwoofer.
2
Connecting an active subwoofer to a car stereo involves the installation of additional components – fuse. To install it should be near the battery.
3
When playing low-frequency sounds considerably increases the consumption of subwoofer power, resulting in increased load on the elements that nourish the automobile onboard network. Therefore, to power a subwoofer install additional capacitor. Note: capacitor to be connected to the supply circuit of the subwoofer, given its polarity.
4
Correctly connecting the subwoofer to a car stereo, go to the speaker setup system. The whole setup is reduced to limit the upper limit of the low-frequency dynamics and to choose the right phase of the oscillation dynamics.
5
Remember: the main problem faced by the motorist-facing subwoofer system - bad convergence of the amplitude-frequency characteristics of the subwoofer and midrange speakers. At the intersection of the frequency response can be either overestimation or failure, therefore, on some subwoofers, there is an option that gives the possibility to adjust the level of the boundary frequencies. If your subwoofer has this feature, be sure to configure it.
Note
Follow safety precautions when connecting the subwoofer to the radio. Do not operate with the engine!
Useful advice
Do not confuse active subwoofer with passive. Connecting the passive devices requires the installation of the amplifier.
