What problem are you having that makes you think you need a cabinet in the back? Also have you changed the 6.5" in the footwells?

I can't speak to the results yet, but with high quality 6.5" pair and a corresponding high quality 8" pair in that little car, driven by an amplifier with good, clean power, I expect it to pass muster. Also just remember that every 3db/w improvement in the speakers efficiency is like doubling amplifier power. I expect both replacement woofer sets to be far more efficient ... coupled with more power from the amp, should have reasonable headroom to push without breaking up. Being both small and in a reasonably sealed environment (though not tuned to anything ... lol) it should be pretty tight.

Okay ... I"m being hopeful!
