Hifonics ZX12D4 (ZX 12D4)

I really like this sub. I got it in a 1.2 cubic foot sealed box and it hits pretty nicely. I downgraded from 2 12" kicker comps (for more trunk space) but honestly this one 12 is just about as loud. It's powered by a sony 800 watt amp. Still breaking in so i haven't really blasted the volume yet but even on low volumes it hits pretty hard. Very nice sub i would recommend it to anyone who's looking to add some nice bump without breaking the bank.

I just installed 1 dual 4ohm model with the Alpine MRP-500 amp and it pounds! I got it in a ported box around 1.3 of space. It gets pretty loud and hits the lows clean. Used to own 2 10" Sony P5 subs and this one 12" blows them away! I recommend this to anyone wanting a 1 sub only application.

I just bought the dual 2 ohm version of this sub to run on my 1000 watt crunch amp and this is great. it's very clear, haven't really tested the loudness yet because i'm still breaking it in, but i have turned my volume past 40 and no distortion. I have mine in a 1.65ft ported box. very close for being a prefab box. so far it's louder than both of my 10" p1's, and its taking up less space. i'm going to be putting it up against an alpine type r soon to see whats better. then laugh when my $80 sub is better than a $130 sub. i'd even say i like this better than a W3.

I've had this sub installed in my car along with the Hitron HA-1000.1 amp also found on this site for a few months and its working great so far. It runs clean at max volume and has survived several 4 hour road trips. A friend of mine has like $1000 of audio equipment in his car and my $250 setup bangs harder. I would definitely recommend to anyone.
