Well after my Acura TL was stolen, I decided to get a new 2006 Honda Accord V6 EXL with Navigation.
It is a nice car, but the stock system in it pales in comparison to the one I had in the TL.
Now, I realize that just changing speakers in the car might actually sound worse than stock, I want to do something to improve the stock sound.
Touching the headunit/Navigation system is out of the question, but adding amplification and new speakers would be what I had in mind.
Now, I am pretty sure that the stock stereo puts out an equalized signal that is going to be hard to mess with. Would a JL Cleansweep be the best solution?
Does anyone know if the stock system has RCA outs?
What is the best way to proceed?

 

Chances of the stock system having rca outputs is slim to none. I would use the Audio Control LC6i + bass remote if the factory headunit has a equalized output. From there you can do whatever you like for amps and speakers.
