    I'm interested in replacing the speakers in my optima because the stock system is horrendous. I'd like to do it right and go with good speakers and a good 4 channel amp to power them, but what size speakers are in the doors? And it also looks as if there are speakers mounted atop the dash...

  8. Wheels, Tires and Suspension

They are 20X8.5 and I'm looking at the Nitto 555s in 235 35 20s or 245 35 20s but I'm really not sure which to go with. I plan on putting springs on it as well just don't know which ones yet.
