[kickerfanatic]

o.k i got a killer deal on 3 18'' re audio sx18 subs.. so now im confused..

i want to get the loudest out of my 1995 pontiac bonneville.. i dont know what system to go with..

here is what i have.. can everybody and i mean everybody give me their expertise advice and opinions.. thanks

both systems would be walled off in my bonneville..

system # 1- 4 15'' kicker L7 subs on 2 kicker zx2500.1 amps.. 1 amp to each pair of subs..

or

system # 2- 3 18'' re audio sx18 subs on 3 kicker zx2500.1 amps.. 1 amp to each single 18'' sub..

i am very very confused.. i cant afford to do this wrong meaning.. i dont want to choose the wrong system.. i want to go to local comps and im not sure what will be best and help me win..

please i want everybody to jump in on this one.. even you meade.. if you can..

I would think that the 4 15s L7 might be louder, because of more cone area. But you could get the 18s moving like crazy off one 2500 a piece.

thats the same i was guessing.. i want whats going to hit the best on the termlab..

and i was also told by people over on caraudioclassifieds.com that the sx18's wont take 2500 rms daily..

and i thought 3 18's would cover more cone area..?

[Brandon15zzz]

The 18's would have more cone area look at the chart derrick824 did, thats pinned in the subwoofer section

also i would just think they would be louder cause of the power difference. should beat though start a build log when you begin. good luck

Well take 4 X 15 and you get 60 and take 3 X 18 and you get 54 i know thats not the right way to figure it out but im bored lollz xD

But aren't your 15's square? Square cones have more area than round ones.

[crazyfrazz09]

yeah i thought the square subs have the cone area of the next size up in round.... example a square 10= a round 12. and so on.....

yeah.. from what i was told by kicker and by all over the internet.. the cone space of a 15'' square kicker l7 is that the same of a round 18'' sub...

so my 4 15's should have the same cone area of 4 18's.. so my 4 15's should be more then 3 18's..

i never used 18'' subs before let alone re audio brand subs.. so i would not no anything about them or what to expect from 3 of them compared to 4 15'' kicker l7's..

[crazyfrazz09]

im not sure but i think the kickers will take that kind of power daily better than the 18's you have.

I would say go with the 4 kicker L7s with that power they would absolutely pound.
