i am buying vince's subs from him and i have a crown vic, i was wanting to mount the subs inverted, will this method sound the same? also ill be building a box and i never built one before, ill be posting a pic of my trunk so ideas or plans will be greatly appreciated. i need a blueprint for a box. that will fit in my trunk. if i have to ill mount them iso barriec. i was thinking of building an amp rack into the box, and adding neon later down the road. i know nothing about fiberglassing, so wood is what ill be building it out of.
