2000 rms ain't that much bro any 18"s only pushing 2k is going to be a waste imho I'd go 15's ported.

Gonna be hard to fit 2 15s ported in that small of a space..

with only 6.5 cu.ft. and 2000w your better off doing 1 beefy 15 in the right box(between 4.5-5.5 cubes), 2 would be pushing it for wattage and cu. ft. at least in my opinion.

2 12s ported

2 12s ported

that to, but was just referring to the choices of 15 and 18, but yea 2 12's would also work.

Yeah 2 12s ported or a beefy 15". whoever said you cant be loud off 2k watts dont know what they are talking about. 2 12s on 2k Is a good daily setup. It doesnt take 100000000 watts and 20 18s to get a nice setup going.

If not I agree with a single 15. And to negolien. There are many lower power 18s. Just because it's 1000 watts or whatever does not mean you have to give them that. Even if you match rms they are still getting way less anyway.

I'm with noloud4u get a nice 15" 3" coil driver and let it rip. That's what I run on the daily. Plenty for me. It's all about your goals really.

What are your absolute maximum dimensions of the box?

Why not low power 18's in IB?

Id do 2-12s, like American Bass XFL 12s, or SQubeds HD3 12s in approx 4-5 cuft @32htz will slamm nicely,and rip that tin can trunk right up.Best deaden all you can in that trunk.My SQ 10s in 4cuft@32htz in the Honda CRV Slamm pretty good.One XFL 12 in 2.6cu ft@34 htz slamms nicely too.4 XFLs in 6cu ft is too small but still serves justice,.Really cant go wrong with a pair of heavy 10s or 12s in my opinion.You can get the box in and tuned with the space you have.Bigger isnt always better.Its how you utilize the space you are willing to give up to the fullest,and getting your electrical right/ect. So much to get the system to perform at its best,and lots to consider along with a budget

I say four 15's. Ported.

2000 isnt alot? or most drivers just have **** poor efficiency?

last setup i had i did a simi vurp box with a pair of 15s and 1800 watts and was into the 150s at 35hz. granted they where pretty peaky but that was the point.

people think these huge RMS powerhanling woofers are better but truth is they are less efficient.

Id say if you have 2k and 6.5 cubes a good low Q pair of 15s would work great. is that before port displacment? im going to assume that its total net volume with port included..

if it's 6.5 cubes after port displacement then 2 DSS Ethos 15s would work lovely in that
