How can we figure out whether the car CD player and the speaker match
Do not count ah, machines and speakers are written on which, do not see you know?
Do not count, car audio specifications are similar, regardless of the European models, the United States, Japan are similar, if you want to change the car CD, the general purchase of the CD will be marked with the power of each audio output, generally in 40 -50W or so, I changed a 45W, slightly higher than my previous CD power, I used to be 40W, but this does not matter, can be used normally in the home audio in addition to different power outside we are common horns 4 ohms And 8 ohms of the points, this situation must not be confused, or else to burn things. So you can rest assured to change it, the general car CD will have 2 sets of audio output, front 1 group + rear 1 group, if you have three in front of the car (6 speakers, high frequency, intermediate frequency and low frequency, Frequency in front of the wind under the two, the front door inside the two IF, rear seat behind the two low-frequency) speakers, then the front two groups in parallel to the front output, followed by a separate set with the rear output
Machine manual on the power ah! Speakers also have ah! Look to know that still count ah! Big brother! It's not a trash!
Ohm is the need to match the horn impedance is less than the design impedance, CD amplifier and speakers are dangerous. Impedance, in addition to the volume (actual power) smaller, will not burn anything.
