What are the options for upgrading? I have a decent panasonic head unit, and 4 6x8's so far. Is there a way to make the 6x8's run high also? i know now they are just there for bass. What have others done to upgrade there system? I have done other stereo work on my last few cars but im confused with how they have it all set up!
Thanks!

be a little more specific, you replaced your mach460 woofers with aftermarket 6 x 8's?

Sure there is a way but how much do you want to spend?
