Boot Build?

[Curt]

At one point I had two 10" subs in my car, i then swapped them out for a set of 350w ministry of sound 6x9's hooked up to a little amp i found in a shipping container. And they sound twice as good as the subs. The quality is so much better. And still just as loud.

I think that says more about the quality of the previous install, than the 6x9s... 6x9s should never be fitted under any cirmcumstances. Ever.

There's no need to have loud speskers in the back of a car, they're just there for fill. As above, IMO you want a nice all round system, decent quality and set up correctly.
