my buddy just got a pair of the new V3's and they sound so clean and hard, after i heard his subs i decided to get rid of my jl w3's and get the ID's. My jl's sounded great but no way close to how good the ID's sound.
i have 1 10" v3 ported in my trunk car. It gets plenty loud and is very musical and accurate. I would go with the single 12" sealed in your truck actually, but if you can build a nice ported one why not.
edit: I used to have the 15"v2 sealed in my car with the same amp and i am happy with the output of the ten. The v3 are a pretty big step up i think from the v2s.
just ordered a pair of these V3 monsters. cant wait to have them, Hopefully UPS will get them here fast. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif ill have plenty of pics for ya'll.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
