15VmaxXL Posted April 27, 2009 Report Share Posted April 27, 2009 (edited) So my future build is going to be 3 18" lvl 4s with 5 voice coils. Going to be powering them with 3 bxi1600s. But i have a few questions... Im pretty sure this will slam, but i always want a 2nd and 3rd oppion. This is going in an envoy xl.. I have 18 cubs without displacement of subs or port to work with. Could go way bigger but i like seeing out the back window. Im doing a single chamber box, ive never seen 3 18s in the same box, will there be an issue with them fighting each other? Im doing subs up and port back, ive heard thats loudest in SUVs I want to run just 2 HC 2400s, will this be enough? and should i get another Alt? I have a 150 amp right now. Wire is all knu kon Any info is great, i always get great feed back from here. So bring it on Edited April 27, 2009 by 15VmaxXL Quote sold everything Link to comment Share on other sites More sharing options...
loganuf Posted April 27, 2009 Report Share Posted April 27, 2009 with that much power a new alt is a must, prbly in the 250 amp range. the 2400's in the back should b good as long as you have a beefy battery up front. you shouldnt have any issue with space in the XL, and you should b able to fit the 3 18's on the top. Your going to need a box thats at least 15 cu. ft, and maybe bigger. if i were you i would wall it Quote 2000 Eddie Bauer Expedition: Alpine CDA 9883 2x 18" DC lvl 4 D2 10.7 cu ft box 33hz knu 1/0 wire amp: Kicker ZX2500.1 Kinetik Link to comment Share on other sites More sharing options...

15VmaxXL Posted April 28, 2009 Author Report Share Posted April 28, 2009 the 2400's in the back should b good as long as you have a beefy battery up front. What would be a good battery, i dont wanna spend 250 on another 2400 if a 800 will be ok. Quote sold everything Link to comment Share on other sites More sharing options...
