Stereo suggestions, thoughts, ideas?

Aaron, Have you looked at the Custom Audiosound stuff? http://www.customautosound.com/
They have many stereos that give you many options. The Secret Audio setup I put in mounts under the seat or elsewhere. It has Ipod and MP3 inputs and is AM/FM. I went this way so that I had a better radio while still leaving my dash stock looking with the factory AM radio in place. They also offer powered speakers with small subs that will fit under the seats. I almost went with them instead of my rear speakers.
