me and my other 2 friends which have gs thought, that standart GS audio system is pretty OK,but when we saw the difference between the original sound and what i'v got now, i couldn't believe how sh... it was as a standart. If u don't believe me come and compare mine with standart. Pioneer dvd unit, 2* 10'' subs and at this point i am still runingt the standart door speakers, and the difference is UNBELIEVABLE!
