Sorry buddy here you go... Im new to fi so im not so sure how much louder the BL is than the BTL....this will be in my daily so i just want something nice and loud. Im use to always buying JL products but im not putting jl in my daily. Im looking to spend no more than 700 for the sub and amp, i already have 1/0 wire in the explorer. My friend has a 12" RE SE in his jeep with a zapco amp im not sure which model and that bumps loud as hell. Im pretty much just trying to be louder than him. THe music i usually play is rap and old reggae with lots of low bass. So all in all im just trying to be a good bit louder than my buddy with the 12" RE SE's. I know i sound like a noob but i just want to buy the right thing for the right price. thanks in advance =) its a ford explorer 07 and i also have all hertz components powered by zapco 360.4
