2 gcon 15"s or 1 18" icon?

[trpkkd 0]

I'm still tossing ideas around and was wondering which would work best in the space I have. I have 44"w X 30"d X 18"h to work with could be a little taller but was hoping to keep it close to 18" or less. I was wondering if 2 gcon 15"s would have more output than 1 18" icon. I'm pretty sure I'm going to run a crescendo bc 2000d at 2 ohms. What do you guys think would have more output? It will be in a 03 ford explorer.

The difference in output between those 2 setups may be only like 1dB. I would go with the icon personally as it is cheaper overall to get one of those vs. a pair of gcon's. You can always make the box more efficient for the icon as well

I'd get the 2 15s. More cone area and coil on tap.
