Car audio conversion is now on the market has been gradually formed a trend, indicating that now people taste the requirements of life are increasingly high, but when we have what modifications need to pay attention? First, try not to change the original car lines “to”, because most mid-range car wiring are quite reasonable, under normal circumstances do not need to re-change. Second, do not tear the waterproof membrane. Remove the door trim general, you can see a layer of waterproof membrane attached to the metal frame, a lot of construction workers troublesome, the waterproof membrane tear while doing easily lead to short-circuit and cabin water. Third, to avoid replacing the original harness. Because mid-range cars electrical equipment more, all using a larger load harness, so do not worry because the load is too large and replace the harness. Fourth, do not arbitrarily increase the amplifier. Many owners say the sound loud enough, quick to add amplifiers. In fact, the audio conversion, speaker is the most fundamental, blindly increase the amplifier will not make better, but will result in degraded sound.
