2- Kicker Solo X 12" (2500w rms & 5000w Peak 2ohm DVC)
or
2- Kicker L7 15" (1000w rms & 2000w Peak 2ohm DVC)
with 1- Kicker KX2500.1 (2500w mono output)
Each sub will recieve 1250 max wattage from the wiring sequence
The question is for the maximum boom with the amount of power at hand which sub will perform better?
(Enclosure depends on the outcome of my research)
if they're getting 1250 watts, and the 15" only handles 1000 RMS, when you really crank it you'll get some distortion and will probably damage the sub. if you want more "boom", smaller subs tend to have a tighter, punchier bass. bigger subs tend to be able to handle lower frequencies and the bass carries better, but my vote would go for the 12"s
u could build a bandpass box for the 12s to get it boomy. gotta guess a bandpass for a 15 will be huge. thats alot of power. r u sure u really need all that? or do u just want to be able to tell people that your system is 4million watts. is your front stage getting lots of power too? that might be way out of balance if the front is getting very little power.
How about this.... pick the speakers that sound the best to you.
If these two choices have met all your other criteria (price, power handling, enclosure size, etc) then go listen to them and pick the one that sounds better. Unfortunately, I nor anyone else can tell you what sounds good to you.
get the 12's...one they will save more space, and once u amp them, they should hit harder!
you know what, go with 2 10 inch subs. I find my 2 12 inch subs are way more overkill than i need for the car. Just my two cents, If I ever buy new subs agaun I will be going that route.
as in too much bass, ive only ever had the 2 12;s so dont have anything to compare it against. But my car rattles like crazy, i geuss if i nailed everything down it might sound better, but im going deaf now as it is.
