Hey guys,

What size speakers can I fit in the stock front and rear locations on my s4? Eye balling it, it appears like 5" fronts and 6.5" rears? Can anyone confirm this? I am guessing mounting would be customize?

Also I'm thinking of running Polk Audio DB651 coaxial rears and DB501 for the fronts. If not the coaxial, than the component versions DB6501 and DB5251. This will be paired with a JL 10W7 and a JL 500/1 amp. I am more than likely going to pick up a Clarion CZ501 Head Unit.

Input before the end of Black Friday would be awsome, haha.
