Trying to figure out a way to add some bass to fill in what the stock speakers lack. I am upgrading to the kenwood dnx570hd for my head unit I would like to find a subwoofer that will fit under the back seat and still sound good. I currently was planning in using an older alpine mrp-m200 amp I have laying around. I am struggling to figure what will fit and still look decent. So far I have only found ken reasonable enclosure that's supposed to be custom and it's on eBay. I am confused on what type of sub to add that will work well and not be too pricey.





So I hope someone can help me out and make a suggestion on what will fit or if there is a universal enclosure that will work well too. Thank you for your help from a car audio rookie
