I have 2 kenwood kfc x133 excelon 5 25 speakers in the door two hertz dieci dcx1003 4 speakers in the dash and two hertz dieci 6×9 dcx6903 speakers running in the rear. They show a typical single channel wiring scheme.
Two 4 ohm speakers 2 ohm load two 8 ohm speakers 4 ohm load two 16 ohm speakers 8 ohm load.
8 speakers 4 channel amp wiring diagram. 4 ohm mono is equivalent to 2 ohm stereo. This can also include any crossovers and circuits connected to the speakers. This is the resistance impedance presented by the speakers that is seen by the amplifier.
If you re wanting to install a 4 channel amp for 4 speakers and a subwoofer but only have 2 stereo channels available that s ok. However increasing the resistance to more than 4 ohms of speaker resistance by adding speakers in series will split the amplified audio output from the amplifier across all the speakers in the circuit. The recommended speaker impedance ratings are usually listed above the speaker wire posts.
This is my first audio install by myself and i m looking for a little advice. This is because the speaker pairs together will be 8 ohms and will require to be at least 1 4 the power for each speaker of each channel on the amp. So if the amp is 100 watts rms 4 ohms per channel then each speaker must be at least 25 watts rms 4 ohms since the amp will push 50 watts rms 8 ohms.
For more power 200 watts rms per. Then access the wiring harness behind the radio. A home stereo for example may often list 6 16 ohms as being ok for use.
Two 8 ohm speakers in parallel is equal to 4 ohms total that the amp will see. Single voice coil wiring options. If you are using a factory radio in your system start by getting an amp with speaker level inputs.
Also attempting to wire two 8 ohm speakers in parallel to an 8 ohm stereo would have the same effect. Check the amplifier s owners manual for minimum impedance the amplifier will handle before hooking up the speakers. Diy audio speaker amplifier wiring guide faq what is a 8 ohm load 4 ohm load.
Hunter this diagram shows how a 4 channel amp and speakers get connected to an aftermarket stereo. The following diagrams are the most popular wiring configurations. When the load decreases the amplifier s output increases.
As shown in my diagram you can connect 2 channels to a 4 channel amp using either the speaker level inputs wired in parallel or by using rca y adapter cables. I m currently trying to wire up 6 speakers to a four channel amp on my suv. 4 ohm speakers unlike speakers at 8 ohms of resistance keep the overall resistance on the amplifier at or near 4 ohms.
Wiring configuration for 2 speakers in parallel.
