I had a 12w3. I would hear the HCCA in a proper box and judge for yourself.
I would choose the HCCA over anything JL if it was a situation where I would get them for free and could not sell either of them to buy something else.
Although I do not have any experience with the HCCA, I've had 5 different 12"s in the JL custom box built to spec and they all sounded much much better than the JL.
What amp are you running now?
The HCCA is rated at 2k, and I have a 2k 12" that sounded good on about 1200w rms, but it could definitely take much much more, and didn't sound any louder than a 900w-1200w rms 12" I had...so there is that.
If you don't have a few batteries or HO alt to power the HCCA, it's not going to really shine and you will probably think it's not that loud compared to the 12w3's.
Keep in mind, everyone likes different things. I prefer my $55 RD-12 over a JL 12w3...enclosure and your vehicle have a LOT to do with your interpretation of a sub.
