I second noble100's comment. If you are near a metro area, you should be able to get some listening time at a few dealers and get an idea of what you like.
Your subs aren't the worst, but not the best for high fidelity reproduction.
Once you have settled upon a speaker, you should consider an upgrade in the future.
Your amp is no slouch and should be able to power most speakers. In fact, I would consider it a keeper.
