yes it would in 1.25 cuft they only need like 800 watts each. Get something that does 1600 at 2 ohms or 2 amps tha does 800 and 1 ohm.

600-700w each...a lil weak there DB fan.Thats like buying a top fuel dragster and only putting in 87 octane gas.

700 watts is fine for a brahma. They definately don't need 1000 watts to get going. I wouldn't risk breaking a $400 sub.

1.25^3 ft. at 800 watts HAH!...You need 800 watts at like 3.5 ft. for the 15" in a ported box...Even more for sealed

 

[IgnoreMe 5,000+ posts]

well for about 1 cubic foot in a sealed box your gonna need about 900 watts claims adire. so i guess in a reccomeneded ported box you might need about 800 watts like stated earlier in the thread. dont take my word for it though as im not familiar with the brahma

call adire and ask them. Brahmas are not anything like xxx's where you just feed them gobs of power. They are MUCH more efficient and do not need nor mechanically can handle as much. 800 watts will get you FULL output in 1.25 cuft sealed.....I don't think it was specified if the box was sealed or ported but you could go with slightly more ported.
