JL Audio 12W1v2-4 12-inch Car Subwoofer Driver (One piece only)

all right this is what I have here in my 1993 Buick Regal you may ask why the hell would you put a system in a 1993 Buick Regal because I wanted to so I did this is my Pioneer head unit uh uh heads it has two preamps got USB here and it's got the auxiliary cable capability what I like about this is that it has what we call an HP F filter also known as a high performance filter what that does is you can change the amount the higher the Hertz is the less amount of lows that your speakers try to handle that pretty much takes the lows out of your speakers and puts them off your subwoofers now you can have that which is really handy because it will prolong your speaker life so I would really recommend getting a head unit with a high performance filter that way you get the best quality out of your speakers sub for two settings if you know how to what to do with all that stuff you can use that
