Newb here- can I hit 140+ with this setup?

[coryo]

(1) AQ 1200d

(1) AQ HDC318 - D2

Running at 1ohm.

Going in a Chevy Avalanche and building a big azz ported mid-gate box.

Let me know what you guys think? More power or just the right enclosure/port/tuning?

[Hotdog]

yes if you have a properly built box

[coryo]

Thx man. Any advice on box design? size, port, tuning?

Appreciate any advice.

for only a 1200d i would make it a big. at least 6 cubes and tuning will vary. 30-32 for the lows or 34-36 daily beating and potentially more spl

3.84929 ft³ after bracing and displacement is what AQ recommends.

That it what AQ's web site recommends of an 18"

109 liters and that = 3.849ft3

seams small for a 18. in there tech questions area they say 5-6 cubes

[Hotdog]

it probably would be 5 or 6 cubes after speaker,Port, bracing displacement.
