see now thats why i was having this problem was because i know the 15s will have more cone area, but on the other hand the BTLs will take a lot more power.
i just didnt want to buy the BTLs when the MTXs would be just as loud.
acutally im going to have three 2400 kinetics in the back with a 300 amp alt.
and no im not, im running the MAs at 14v not 16 were they make the most power but it still pushes the 9500s with a conservative gain
