Well you have given us the right info as far as knowing what you want (an spl system). If you are wanting to keep the factory deck, a product like the JL Cleansweep might be your first thought. As far as obtaining high spl, there are many, many woofers capable of this, the factor that will make or brake this will depend on the woofer enclosure. Keep in mind that it isn't always necessary to have the most "powerful" gear, this can save you money in the long run. Are you considering to pay for the install or are you a d.i.y?
