well right now im running a single 15inch Kicker CVX and i love it its loud but i want to go louder i just dont no what to do....im thinkin about running another 15 or swapping out the amp and sub and gettin a new amp and a single 18...what u think is gonna be a louder setup a single 18 or 2 15s?
It depends on how much power you give each. If you give 2 15s 1k or 1 18 1kw the 15s will have a cone area advantage. Now if you can give the single 18 more that's a different story.
