This is the remain of the system i had in one of my last cars. I took this off and left the replacement speakers in the car.

I was wondering do yall think that i should put this in My LS and if so do you think i should replace the stock speakers throughout and I also have a Pioneer AVIC N1 that is not pictured that i would like to install as well as soon as i find a way to install it.

If the pictures arent up here is the link to my cardomain

wow that looks serious id do it just make sure u do it right and use that tar mat i think people used to say the trunk gets messed up real easy

i would install those subs for sure along with the head unit even if you don't replace the factory speakers (unless one is blown). honestly the factory speakers sound good enough for me and my preference.
if you have too much money and don't know where to spend it go ahead and buy door speakers and put some sort of sound deadener in the trunk
