bro it's little bit long, not that much, as it is slim so u can also place it horizontally.............i suggest u to buy vtrek mono, very gud amp, as for some ppl said use alpine, they both aregonna bang this sub same ,but will have little diffference in clearity........and i have a box design for the type r , that's gonna bang ur sub very hard, u will definitely feel a boost up of perfomance....
