Do I have enough space????

[kowboy 10+ year member]

I have a sundown 3500d, and exactly 8 cubes(net) to work with in a trailblazer. Can I get away with two 18's that require a smallish box? Or should I just do two 15's? Single 21" warden maybe? What do you guys think?

you have 8 cubes for total box size, or 8 cubes volume for the sub?

im thinking he got his net and gross bass ackwards

Im thinking, if its 8 cubes total to work with, go with a single 18, but if its 8 cubes airspace for subs, go with 2 15's

guess we will have to wait for him to hit the refresh button to find out

Box is already built, and 8.4 cubes remain after port - before sub displacement... I guess two 15's would be best, but I was just looking at t3 audio t.2000 18's and their website states they only need 4 cubes each. Same with treo ssx 18's - 4 cubes "optimal" ported. Just trying to get the most bang from the space I have to work with. What sub(s) do you guys suggest?

Morning bump.

Cone area is king. if the 18s will fit, do it. (Treo!)

but how did you build and tune the box without driver displacements?

driver displacement will be .23 or something along those lines for 15s...that brings you to a little under 8 cubes so just do 2 15s.... any of the subs you listed would work but arent cheap

I'd do a single 18". There's no way to know net cubic feet until you know what sub your using, so that must be gross.

So you would do a single 18 in 8 cubes as opposed to two 15's? Even though the 15's have more cone area?

What 15's would you do? That perform well in 4 cubes each with 2000 watts...

what do you have? a box with no holes cut in it? or do you have 8cubes of available space in your vehicle?
