did any body with the nav system setup do a audio system upgrade (iE add subs and amp etc ) with out changing the radio???

if so what did you how

how does it sound

do you reccomend

also does anyone worry about voiding the warranty if you upgrade you audio system ???????

 

definitively it shouldn't void the warranty. How does it sound? depends how you integrate your OEM HU into your system. If U use the 3Sixty.1 by RF I assure you great final results
