I dont think im going with the 2 15s more or less 2 12s and im sure i do get the at cost. www.hifisoundconnection.com is where i get my stuff for only 300 bucks i can get a 800w max amp 2 12s in a box and a amp kit sounds like cost to me, Also i agree with the dyno mat although i dont have the ***** to drop my headliner out so ill be putting it in every panal i can get my hand on.
