[anyone else in Utah?]

Do any of you guys make it to the several db drag events around salt lake??? Our team went to 4 this year and they were pretty fun!

[Underestimated systems? SPL/DB;s?]

Reminds me of the old Powered4Sound days. They were doing some fairly nice numbers with two 6.5" Audiobahns in there Doubleshot style boxes.

[99' durango opinions]

I have the same durango and I am doing a monster build in it.

Just a FYI, the resonant frequency is @ 49-50 hz

Sound deaden the roof and all doors including the hatch!

I would look into Kinetik or PowerMaster for batteries and either DC or Mechman for an alternator. I can get you a custom built one for your durango as I have a couple of them.

[is it worth it??]

I would never even consider making that trade... The '06 and up RE XXXs were IMO one of the biggest disappointments in CA history. The previous xbl^2 XXXs were some of the best all around woofers ever made and still retain incredible value. I've seen some of them today going for more than they cost brand new in 04 + 05.

Werd!

I have a couple motors and such...... my favorite OVERALL woofer of all time!

Once I get out of the game.... the XXX's i do have will be used in my personal vehicles

[re xxx's?]

The XXX's do get loud. I have two XXX 15's that are not very common. Triple Stiff spiders and larger tensils. somewhere around 2200 rms. One of them is Brand New In Box..never even taken it out.. Im willin to sell it if anybody wants it. Burped a 150.4  @ 45 hz with a T3000BD RF amp in a 5.0 box @ 32 hz!!!

Rare for you maybe, I know where theres 6 just sitting right now

Yes rare for "ME" well when I had RE do it, they said I was one of the first to have triple stiff spiders done to a 15" XXX.... so ssssooooorrrrryyyy
