Rear Subwoofer Deck??

[machsv103]

I have always just put subs in the trunk in a large box but I was wondering if there are any good subs that I could put in the stock location. Do they even make decent 6x9 subs that are better than the stock THX ones?

I would suggest going with a common sub size, and either unplugging those rear decks or using them as midbass drivers to compliment the full size subs.
