More cone area and more voice coils to handle power and heat better! 4 15!!!

Well what kind of vehicle that can have alot to play with it to but if your choosing between 2 18s or 4 15s then space shouldnt be a problem???

id do the 15s cuz thats what im already doing but the 2500s will be more power than the subs are rated for 2500 divided into 2 is over 1000wrms by far. id just wire all 4 together and get a 3500 or so wrms amp at 1 ohm. would be so much better.

we know those amps arnt just gonna do the 2500wrms

This setup will be going into a 2004 Lincoln Navigator. So there will be plenty of space.

i dont have enuff room to wall it so i have to clamshell. ur gonna wall the 4 L7s that **** will be hair standing nasty. i had 2 of the L7s in a regular box with a zx1500 on them and it was amazing. u do 4 and zomg it will be insane all 4 wired to 1ohm. im doing 5cu/ft each after all the displacements.

Wow this thread is poop. The 15's have an obvious advantage but its all install depended. However, either setup would be excellent off two ZX2500s.......

We do 4 R.E SX 18s in a 04 and that thing would hit some lows also it was tuned to 32 Hz we had it with subs forward ports to the back.

subs forward? pics? thats seems like it would look awsome!

BTW OP i went from 4 15" Kicker L5's in 17 cubes tuned 37hz too 2 18" RE SX's and honestly GOT LOUDER!!!!! maybe it was an flaw in my install but these 2 18s murdered the 4 4L5's by far and by the way i have less power going to the 18's!!!

No ****!! I actually had 2 15" L7's connected to a RF T20001bd and it was loud but heard someone else that hit a little harder than my setup than I found out he had only 2 12" RE Sx Connected to a RF 1000bd. Then again I had a shitty prefab box. But believe or not I actually am going with the FI BTL 18"'s.

Thanks guys,

Go with 4 Ascendant Audio Havocs 4 Fi Qs or better yet 6 FI SSD 15s. All should kill the kickers in SQ and SPL ....but once again install dependant

 

[Kenneth10483 10+ year member]

Box is the main thing make sure its strong as possible any flex will make a difference. Ask Fawd06 about a box he built and once he got all the weakpoints out the box it gained 6 DB

I just noticed that the FI BL 18" Come with Dual 2 options, So would 2 FI BL 18" D2 work for each Kicker kx2500 which is 2500 watts at 2ohms.

Ive heard it mention that the BL's really get moving with about 1500wrms to one. Im sure a kx would do them fine...
