Hifonics HFX12D4 12-Inch 1600 Watt HF Series Dual 4 Ohm Car Subwoofers, Pair of 2

Bought a pair 2 years ago and they are still hitting hard. Got them running off a planet audio 1500 mono Amp at a 4ohm load. Could easily add 2 more for a 2ohm load. Key thing is to not to over power them. 175 watts rms per voice coil is substantial enough to power these inexpensive tight bass subwoofers.

Used it for 3 days before they blew on me. Did not sound as strong as well for what it was.

They look good but the quality of performance really not there. They blew a week after I installed them. Didn’t even make it through the break in cycle.

I was going for a medium cost system and bought two pairs of JBL 3 -way 6.5 inch speakers for the used '94 civic I bought. The speakers were great, but when I really turned the volume up, they'd start to distort a little because they couldn't keep up with the bass/I bought a Pyramid PB618 2000 watt 4-watt amp and a pair of these and set my door speakers to all run off channels 1 & 2 on high pass and ran these off channels 3 & 4 on low pass in my trunk.These added the real bass sound that my car needed, I have them in enclosed boxes turned up maybe half-way on my amp with no bass boost, have the bass on my head unit set to -5, and they are still ridiculously powerful. They keep right up as I put the volume up unbearably high. Honestly I think I only needed one of these, but I did want to keep my L/R sound. These are awesome - they get very loud and sound clean, and I have yet to test their limits.

I got these to fill a void in my commute car and paired them with the Hifonics ZXX 500.2 running them as 2 Ohms per channel which is about 90 Watts RMS each and they filled the void. These are not to win any SPL contests but they do flesh out the lower end of my music quite nicely. The only time they don't sound good is if I turn the music up enough to resonate the metal in the trunk, but that is the car's fault not these subs. 3 stars on easy to install because of the spade connectors and their type (one small and one large) luckily I keep these on hand and have a Klein crimping tool.

The speakers look very good and seem to perform well and a real value.

I was skeptical when I saw tons of negative reviews but the dude I get to install my subs said these are really good for the price so I took a gamble and bought these and was pleasantly surprised. Not only are these loud and good for the price but they don't blow after a day like many reviews state. I have these set up on a 4 channel amp and they work completely fine and sound great no complaints so far. Just make sure you get someone to tune your amp for you when installing these because they have worked great so far for me.

2 of these run at 1 ohm on a Rockford fosgate M750.1D. They do not handle the claimed RMS power or max. I weird them per the instructions. In a per spec ported enclosure Easley started smoking at half to three quarters volume. Don't get me wrong they sounded great till they start smoking. Be careful how much power you put to them.
