W123 and more bass

Ok, I want more bass. I'm already installing a some MB Quarts all the way around. Stock sizes though. FYI,I've got an 84 300D turbo. My deck is a Pioneer Premier series I don't quite remember the number though. I'm in the market for some subwoofers. What are your preferences when it comes to subs. I like the Infinity unit. What about some Bazookas? I would prefer a powered sub because I don't what to take up too much room in my trunk. What are your recomendations.

I personally have 2 soundstream SPL-170's 15 inch subs. Which are great and I wouldnt have anything else, except maybe JL audio subs. The great thing about JL audio is the make different models to fit every budget, they make pre-fabricated enclosures so you dont have to jack with it, and every single sub is very musical and sounds good with a wide variety of music. So I think that you really cant go wrong with JL.
