2 Orion Xtr 124's powered by Coustic600se spl in the back of a lancer??

[MrFree]

I need to build a new box for my girlfriends 03 Lancer Oz .If anybody could tell me what I am doing I would appreciate it so much.I have built a box before but by the time I had homedepot cut it,it was 45Hz.So this box I would like to do it right.Could some one point me to some tutorials or pdf's so I can Find what I am looking for(SPL box building for dummies) I personally would like to try an areo port on this box? If you dont know of any reading material could you give me the basics.Thanks and I appreciae any and all advise..I ask alot of questions on this forum ,and I hope it doesnt bother anybody.I just want to know what I am talking about so I dont end up on that pretentious asshole forum about wild claims..I have 2 sets of 12's,I have Orion Xtr 124's and Hifonics HFX 12d4's.Now the hifonics claims 1 db higher than the Orion. And the Hifonics is rms 400/800,Orion is 250/500 music..Which speaker should I use for best spl numbers.I mainly listen to the lowest and hard hitting rap song's a couple dubstep and bass song's also..Could someone help me please..Thanks

that 1db is sensitivity, which is a pretty useless number. "spl" LOL. no one can tell you which will get louder. its fucking impossible. chances are the higher powered woofers are going to be louder.

either woofer wont really work well because they're dual 4. that amp can only do bridged at 4 ohms. dont run stereo, cause its pointless imo unless the bass in the music is 50/50 on the left and right channels, which rarely ever happens.

if you DO wire it in stereo, you probably wont even notice a difference between either woofer since its like 300w per channel

Thank you sir...I think I am going with the Orions.The Specs from the owner guide says — Box Parameters —

Vb = 1.5 cu.ft

V(total) = 1.705 cu.ft

Fb = 40 Hz

QL = 6.288

F3 = 33.47 Hz

Fill = none

— Vents —

No. of Vents = 1

Vent shape = round

Vent ends = one flush

Dv = 4 in. (102 mm)

Lv = 11.26 in. (286 mm)

Now all I have to do is double that I am quessing, for 2 12's...Question? the specs say 40Hz if I tuned to 32Hz would I be louder?? or just Lower?? Or should I just tune to factory specs(Excuse my ignorance) AND Is there better specs for an spl box in a 03 Lancer Oz..Thanks and excuse my ignorance
