k my sister just got a 2003 mustang V6 vert with a mach stereo.... is there ANY reason to upgrade the sound system if the car is like brand new? i think its a waste

 

the factory system should not break out into a big fire if that is what you mean.......

 

is pretty good for a stock stereo, but like any other it lacks of bass so if she listen to rap and that at full blast the speakers will get damaged eventually, i never had problems with the speakers, but my cd unit wasn't ejecting the cd but after like 5 minutes so i upgraded my stereo put a pair of 12 in the trunk and kept the stock speakers...[sm=icon_rock.gif]
