Most car owner always loves to change their original audio system in their car. Some of them still keep the original CD/FM system, but they replace the speakers and add with new subwoofer. There are a number of factory audio systems that have good sound but didn't quite make the grade to be considered among the best. These include a few sports cars with great audio gear. However, their cabins tend to be significantly noisier than the best luxury cars. This resulted in a downgrade of their total system. In addition, there are the myriad of Bose systems offered in many cars. As good as they are, we find that the Bose systems we've heard impart a sonic signature that seems to emphasize the bass and a bit of the treble - not unlike a loudness contour. Attempts to mitigate the signature with tone controls were not entirely successful for us.
If there's a weakness in mobile audio systems, it's in the spectral balance. Many car audio systems tend to overemphasize the bass and treble, because manufacturer thinks that's what impresses most consumers. In the long run, however, the 'boom-hiss' sound is tiring. The best sound systems present a neutral tonal balance (so long as you resist the temptation to crank up the bass and treble controls). Do you prefer more bass or treble? Before you replace or upgrade your car audio system, you should know what kind of car that you have. The most important about this matter is that you must understand what kind of music that you always love to hear when you drive your car on the busy roads. There are a lot of brand in the market such as: Pioneer, Blaupunk, Bose, Sony, Kenwood, Clarion, etc. You can combine your audio system with different brand and type. It’s a good idea if you discus your idea with your friend who really understand about car and audio before you decide to buy a new system. Have fun.
