Jl audio rates their subs to be matched to their slash amps which have RIPS technology its 600w because a jl amp puts out the power 1-4ohms and 12-14.4v voltage drop and impedance rise have virtually no Effect on them. Unlike ither amps it might be a 1200w amp but after all factors put im your only seeing like 400w or something. The w6 can easily take a 1200w rms amp
Great sounding sub with a full low end that can take some power and have strong output ported.
You most likely had it in a JL prefab which is junk for low end extension. Its all in the enclosure. You have have the most expensive sub in the world perform like mediocre bargain subs in an inadequate enclosure while you can have flea market subs sound amazing in a proper custom ported enclosure. Enclosure specs is your first concern you need to address. Measure out in Length X Width x Height of what you have to work with trunk space wise.
space makes bass man. If you dont have the space, you wont have the lows. You'll have to go down to a 10" sub with an aeroport for fiberglass trunk corners. Sealed wont get you impressive lows, it'll just be apparent and sound okay. You'll need at least 1.25 to 1.5 cubic feet of NET airspace after port and subwoofer displacement for any real results. Which is what i think happened with the 13W7 which i know plays down to 25hz with authority when in a 3.25 cubic foot box tuned to 32hz, sounds smooth, clean and tight too.
Ya i'm always on the lookout for used, but I haven't seen any quality subs on CL for a while. I picked up that 13W7 for $300 haha. Picked up a 1000/1v2 for $300, had to pay $180 to repair it though... still have that one, great amp, the leads on it need resoldering though. Anyone want it for $300 + shipping?
I built a really solid box out of (I think either 3/4" or 1") MDF, to spec for it, but it was sealed.

I'm guessing you and the shop only know how to do it based on looks and not actual sound performance hence the dissatisfaction. 1 cubic feet for a single 10 ported is still on the small side. I'd highly recommend you taking it to a shop that actually knows how to get you loud and good sounding rather than a place thats just flashy. Ported trunk corner can work but you'll need to give up more room. Space makes bass, Nothing will change that. Enclosure design is everything. Port tuning, port area, how they all work along with the sub's electro mechanical parameters, subwoofer loading etc... all are factors in getting you proper sound. Its not just buy a nice sub and stick it in a sealed box or a poorly designed ported and get amazing lows. Sh*t doesnt work out like that.
