Advice 1: How to connect speakers to the amplifier

To connect the speakers to the amplifier, it is necessary to replace the standard factory wiring acoustic more powerful. For this purpose, use a speaker cable section 2x1,5mm with a stripe along one conductor as a regular acoustic wiring is made of wires of smaller cross-section and has a resistance, which lost 30% of the power strip need to determine the polarity of the connection.
You will need
  • To buy a suitable amplifier of appropriate power, dynamics and a set of power and speaker cables. Power cable with a diameter of 8mm are ideal for power amplifier 4x50w and 15mm for amplifier 4х100Вт. Speaker cables should be at least 2x1,5mm, in addition, you will need a fuse rated for currents up to 60A and the holder for it should also have a linear wire and a control wire.
Instruction
1
Standard wiring can not be removed, it does not interfere, it is necessary to cancel the card it will come in handy for other purposes, for example, to connect stop lamp, additional turn signals. Disabling regular acoustic wiring, proceed to pull the new speaker wire. To tighten in the door, use thin steel wire. The wire preferably tighten inside the regular corrugations. So it won't be noticeable that the machine was doing something, and on the other hand, the manufacturer took care of the path layout of the wire harness. Tightened the door wire need to be fixed the same way as was secured regular wire, then it will last a very long time. Inside the cabin of the car, acoustic wire is preferably laid in a single wiring General wiring. Finished one door, you can put a speaker on the prepared place and plug in the appropriate polarity.

Remove the front seat, placed under a Mat, a sheet of plywood 10mm thick. It will be attached to the amplifier using the screws. Putting an amplifier on his future place, put the seat back and try to when moving the seat, it did not touch the amplifier.
4
If all goes well, proceed to the output power of the power wire to the amplifier in the engine compartment. For this purpose in the front wall of the body of the drill 16 mm hole and insert the rubber ring with the hole for the wire. Threading wire and pull it to the positive battery terminal.
5
Attach along the entire length to the wiring harness or using clips for attaching wire to the body and connected to the positive battery terminal. Near the terminals, it is necessary to install the power fuse that will save the machine in case of short circuit at the other end of the wire.
6
Output positive power wire to the power block of the amplifier and plug it in. Next, connect the power negative. In contrast to power plus, it is not necessary to pull so far. It is sufficient to connect the vehicle body with the bolt M6 at the nearest convenient place and do not forget to clean off the contact paint, and that it is a good insulator.
7
When the wire is attached to the body, the head of the bolt from the street must be covered with a layer of sealant.
Now, plug the speaker wires according to the diagram, drawn on the acoustic block and plug-in Manager and line wires. Connecting them to the unit, check the how it works custom amplifier and put the seat in place.

Advice 2: How to connect speakers to the amplifier

Amplifiers audio frequency made in the form of separate blocks, the design so as to allow connection of any suitable parameters of speakers from other manufacturers. They are equipped with special terminals, allowing connection of cables without using plugs.
Instruction
1
Use to connect the speakers to the amplifier cable of sufficient cross-section. First measure the resistance of the speaker system in the usual ohmmeter, not touching the terminals and probes in order to avoid influence of the voltage of self-induction. Learn from the instructions to the amplifier or of the rear wall, how much power he develops under load with the same resistance. If you have specified that the impedance of your speakers to the amplifier too low, enjoy other.
2
Calculate the current that will pass through the cable. To do this, use the following equations:U=IR; U=P/I, hence P/I=IR, P=(I^2)R, I^2=P/R therefore:I=sqrt (P/R), where I is the current in the cable, And the P - amplifier output power, W, and R is the resistance of the speakersin Ohms.
3
Cable be sure to use copper and stranded. Practice shows that special expensive speaker cables improve sound slightly, so if you are not an audiophile, use the normal cable available for sale at the store of electrical products. It section select in accordance with the table: http://www.eti.su/articles/kabel-i-provod/kabel-i-provod_32.html. Pre-measure the distance from amplifier to each speaker. In the store ask them to cut the cable with some slack.
4
With each of the parties will clean up both the cable conductor for a length of about 8 mm, and then saladita to the conductors better held in the clamps of terminals. The isolation of lived mark with a red marker on both sides (to search for the opposite end of the wires, use the ohmmeter). If the colored wire insulation, wire marking is not necessary.
5
Unplug the amplifier. To insert the core into the terminal block, pull the plastic lever to the side opposite the hole for the conductor, insert the conductor, and then return the lever into place. Guided by the labels or colors of insulation, depending on the type of cable, connect the red and black terminal of the amplifier to the terminals of the columns having the same color. If the polarity is confused, the column will not deteriorate, but may significantly deteriorate the stereo image, or to drop the volume.
6
Connecting both speakers, turn on the amplifier and the desired component stereocomplex, then check the operation of acoustic systems.
Note
Obestochivaete equipment before any operations with the cables.
