3 18 Lvl 4s W/ 5 Vc

[15VmaxXL]

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

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

hmmm so lets have a vote...

wall or box with subs up ports back..

Well news is i have all 3 amps now, next is going to be alt and batteries.

Then for the subs

[sri3850341]

im almost sure you could double the power to each sub....

i say wall

[Zade08]

Ya just go with the xl. It was made to replace the lvl4 w/ lvl5 coils if Im right. I would just take the plunge and wall it off. lol. 3 18s is alot od speaker area. lol. Wall it.

Ive been told tho, that the xls dont get too loud till around 2k rms.

im about 600 less that a sub.

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.

Ha i know they would take it all day but i already have the amps so i wanna do 1600 rms each.

Maybe down the road 2 1600s on each sub... who knows lol.
