What is the most compact way to get some bass in my 91 hatch? I do not want to put a big box in like the PO had. My 79 had a tube woofer I could plug and bungee cord in the back or put on the back seat floor with the back seat down. Now, I will be using the back seat and do not want to use too much hatch space. Are there any big bass 3 way speakers that for in the stock spot or a small, custom fit box for a corner?
