What are the speaker sizes from and back in a 2003 Toyota Highlander? And a good brand with good bass?

I want to re place the speakers in my 2003 Toyota Highlander Base 2.4L 4 Cylinder. Right now they are stock and blown, and if so, could you tell me a good brand that makes good bass? Please, i really need help! I'm more into engines, not electronics. Please help me!|||http://www.crutchfield.com/app/car/carse鈥?/a>





I like Boston Acoustics.


Think about adding a sub if you want more bass
