The 10" sub in my 02 Monte is ported into my cabin. Permanently removed the back seat, built a firewall and now am in the process of finishing the audio install. Both of the amps are mounted inside my car's cabin on the rear firewall and the 10 is poking into the cabin from it's trunk mounted box. Will let you know when the install is finished in a week or so and tuned as to how things are sounding. Will post some pictures too. Hopefully it works out pretty trick.

I have a 15" mounted to the rear view mirror. Lots of flexing in that sucker.
