I have a 2007 acura tsx with navi and supposed to have PREMIUM SOUND SYSTEM

yeah right. I want to upgrade sub? I am wondering if it has a sub already the one i almost purchased before this advertised a sub but who know. i don't want it to look tacky id love to be able to put the sub descretly and not weigh down the car much. any pointers to beef up the sound would be greatly appreciated thanks. i guess the two main questions does it have a sub and will me adding a sub void the warrant? also could an acura dealer beef up my sound system it cannot seem to handle bass at ALL it drives me crazy. thanks for your help

no this would be a complicated process, my audi had premium sound, which means that to add a subwoofer, your car would need to have to have all the speakers rewired, becuase you car does have a small acura amplifier that must be bypassed
subs dont add too much weight btw.
i am not sure if your model has a sub, but adding one should not void the warranty, id be surprised if there is any warranty on the speakers
