Sealed midbass pods are awesome if you can fit them. I don't nessecarily see the need for an 8" midbass, but then again I'm running a very large substage and the Anarchys can pound on their own.I will definitely run 3-ways, that much I know. PS Sound put a pair of 8's in the Kicks 9f a TT about 3 years ago that crushed the SQ competitions. Fully enclosed not IB. This I would consider. But that would depend on the car and choice of Sub. None of this is happening in my current vehicle. I lost the car I wanted to put a system in due to an accident. What I ended up getting was just something to hold over while I work to start a new business and wait for the auto industry prices to land back on earth.
