济南汽车音响改装http://www.sdcarmusic.com/介绍声压就是由声音的音波接连的散播，对空气产生推挤动作而形成压力，下面济南汽车音响改装的有关专家就给大家详细介绍一下增大声压的措施。

1、济南汽车音响改装介绍车内如果有很多空隙通到外面，音压无法累积增加，所以测试音压的时候，必须隔绝空气外漏，如冷气出风口、排挡杆、门缝、排水孔等。
Jinan introduce modified car stereo through the car if there are a lot of gaps to the outside, the sound pressure can not be cumulative increase, so the sound pressure of the test, you must cut off the air leakage, such as air-conditioning vents, shift lever, door, drainage holes and so on.

2、济南汽车音响改装介绍提高超低音喇叭的承受功率，增加扩大机的输出功率，喇叭串并联之后的阻抗最好等於低音扩大机的最低承受阻抗，如此可以让扩大机完全发挥。
Jinan modified car stereo subwoofer introduced to improve the affordability of power, increasing the output power amplifier, speaker series and parallel impedance equal after the best bass amplifier impedance bear minimum, so you can make full advantage of the expansion of the machine.

3、济南汽车音响改装http://www.sdcarmusic.com/谈到同样的喇叭单体放在不同的音箱上以同样的扩大机输出功率去推动，音压会有所差异，然而，反射式的体积比较大，承受功率也比密闭式的低，如果扩大机的输出功率不大，选择反射式的会比较有利。
Jinan modified car stereo speakers talked about the same monomers on different speakers in the same amplifier output power to promote, sound pressure will vary, however, reflective of the relatively large size, power handling than the closed-type low, if the amplifier's output power is not selected would be more favorable reflective.

4、低音箱以高密度密集板为佳，合板中空气太并不适合，另外透明压克力音箱，如果压克力部分面积太大会降价音压，音箱的结构必须坚固，木板之间的接缝必须以白胶填入，不能有漏气的现象，另外出线端最好加上橡皮垫以增加密合度。
Low speaker intensive high density board better, plywood in the air too is not suitable, another seam transparent acrylic speaker, acrylic part of the area if the price is too Assembly sound pressure, speaker structure must be strong, between the planks must fill with white glue, can not have leakage phenomenon, while the outlet end of the best plus rubber mat to increase adaptation.
