Can anyone help design an enclosure for my subs (Precision Power A12 specs on site). I have 2 and they are being powered by a Soundstream Picasso P1.1500D. The subs are 2 Ohm DVC, each sub is wired up showing 4 Ohm load and amp is therefore producing 1000W at 2 Ohms. The fixed height and width I have to work with is 14.5 x 40". At the moment they are in a prefab enclosure each sub in own sealed 1ft3 section but not really giving enough output. I listen to a wide variety of music but would like something that pumps out bass. Any further info please post.
