What car subwoofer brand are the best these days?

My 2 12 inch JL audios finally blew after 3 years of flawless use. Sad day. So it looks like I'll need to replace them. I got those cause they were the cream of the crop back then. My question is what are everyone's opinions on the cleanest sounded subwoofers on the market these days? I'm looking for

My 2 12 inch JL audios finally blew after 3 years of flawless use. Sad day. So it looks like I'll need to replace them. I got those cause they were the cream of the crop back then. My question is what are everyone's opinions on the cleanest sounded subwoofers on the market these days? I'm looking for the same 2 12 inch subwoofers for my mustang. Any amp recommendations would be nice too.

JL still has some very good subs – usually leading the way in R & D, great support, all that. You pay for it, of course.
Sundown Audio has come on the scene in the last few years and has quickly become one of the more respected subwoofer brands.
There's Soundqubed for the not-so-expensive options, but still good quality.
RF, Alpine, Kicker, all produce plenty of good options.
Ascendant Audio, Fi car audio, Sound Solutions — and a few other "off the beaten path" brands are worth checking out as well.

NVX, HiFonics, Alpine Bassline, they are all good and it's a very subjective subject, the "best" subwoofer is the one that sounds the best to the person that is intended to listen to it..
I wouldn't buy JL's overpriced drivers, they make good stuff but so do lot's of others, for half the price or less.
I just bought a pair of HiFonics HFX12D4 (12", Dual 4ohm Voice Coils) subwoofers for $54/pair and you might think it must be junk for that price but they are perfect enough for me and most likely perfect enough for you as well.. Two of them in a sealed enclosure wired for 2-ohm and hit with 500 watts RMS, they pound the ground and make my insides move around..
Don't worry about the best, what I do is goto Sonicelectronix.com and look foir the subwoofers with the most reviews, if 127 other people said it sounds great then i take their word for it 🙂

Kicker but your gonna have to spend some money and get a good amp or else your wasting kickers potential.

Kicker or Alpine

Can't go wrong with JL again – they make good products.
