Car Audio Subwoofers

(UPDATE. These subs have been sold. I sold them to a friend and ordered 2 18" Fi BTL's and am build a wall in my F-150. Keep and eye out for updated vids.) I just had these installed the other week and finally made a video. Im working on a cover for the amps on top of the box. 4 12inch Memphis CM's on 2 Soundstream 3000D's. Stinger 0awg wire. Optima Redtop dry cell. 800.4 Soundstream for the mids and highs
