No, decent 6.5" or 6x9" can give plenty of bass for most people. I suggest not going JL Audio for anything. They're good all around, but better can be found all around.
Focal for your speakers. They're better and cheaper. Alpine, however, is a fine deck. I would recommend Nakamichi or Eclipse above Alpine, but unless you go Ebay, those will cost much more for being marginally better.
If you're really set on JL Audio speakers, it won't sound bad, but you will pay a lot more than you need to.
