1 15" or 2 12"

[Gustav Gutta Persson]

Like the title says so wonder I what I should chose, 1 DC XL 15" or 2 Level 4 12" (the amp will be a 5.0k)
I wonder what sound loudest and what will do most pressure

[Souldrop]

It will really depend on the install. There's no good way to tell which will sound better due to so many variables. The only thing I can say definitely is that the 2 12"s will have slightly more cone area,but again how they sound will depend on install...box, tuning, placement in car....I haven't used DC audio, but 5k seems to be a bit high to send to either of those setups?

[Gustav Gutta Persson]

ok, so for the pressure will it be 2 12", and for the rest depends on box, car and tuning? if i got it right

[Souldrop]

To be perfectly honest you could pick either setup. There's no way to tell which will be louder in your car without trying both setups in several different box designs/placements. Maybe the 15 with less cone area will work better in the space? Maybe the 2 12"s will be louder? Who knows? Pick whichever setup you prefer. There is no good way to tell which would be louder. Your best bet would be to pick one, ask questions from people who have run them, and experiment.

but for the pressure (not loudest now) so is 2 12" better than a 1 15"? beaus it have more cone area.

[Noel989]

Absolutely no way to know unless you try them both

And a 5k is way to much power for either sub choice. A 3.5k would be a better choice for your sub choice. If you a 5k get a level 5 or 6.

[Gustav Gutta Persson]

is it a big different on a XL and a level 5?

[Miguels]

too much amp for subs... it will be a fail

[Gustav Gutta Persson]

ok I will only get a 3,5K amp instead
but is there a big differences between a XL and Level 5?

When given the choice of power or cone area, I recommend going for cone area first if you have the space for the larger box.

If 2 12s con handle more power by a comfortable margin than a single 15 then you have both the advantage of increased cone area and increased power handling, this can generally speaking works on your favor but a definitive statement can't be made between two particular products unless the differences are ridiculously large.

From there it's all in the setup, plan your whole system before buying anything, strong electrical, clean signal, box design etc. will determine if you will get the most of your sub or subs. NEVER try to fit subs in improper airspace or incorrect aiming, like the guys trying to fit a 18" in a regular trunk car.
