You can probbaly score some kickpanels from one of the cavalier/sunfire/fire forums for pretty cheap.

Have you thought of that?

 

Those Q logics are crap my buddy got them for his 94 sunbird and didn't fit worth **** and they did look like they where firing up into the dash, he called sounddomain and they sent all his costs back, shippping, duties etc etc... and they where so cheaply made..

 

yeah..... those Q-form are definately good for quick kicks. But they're made out of molded plastic, so they'll resonate at some point. It could be treated to some degree tho.
