Alphasonik Mayhem

Great sub and it's very loud but it didn't last very long though and if you played it hard you could smell the voice coil burning all the time. I only had about 1800 watts going to it with about 8v of line drive.

I wouldn't purchase another one being that the frequency response isn't very low and it burned up pretty quick.

I don't know what other reviewer was talking about.

I have 2 of the PSW912 (and I have owned them for over a year now). I think the other reviewer was probably either under powering them or simply abusing them...not to say I don't put them through torture, but these things are insane. I have 2 Alphasonik PMA1200DA, 1 connected to each at 1 ohm each amp and I get compliments all the time. The bass is unbearable at full volume (it's that loud) and if I go to the golf course with it up even at 50% they complain inside the clubhouse about it.

OMG WOW!!!

I have owned this sub for over a year now, in a tuned ported box built to spec. I am powering the sub at 1ohm 3200 watts and it eats it like candy. I will attempt to put more power to it next week. There has been no burning smell of the voice coil and it definitely hits every note. Thank you Sonic Electronix for the awesome investment.

Great Value! BEST SUB I HAVE EVER OWNED BY BRAND!!!

Best sub ever owned I have been bumping this on 1800rms amp @ 1 ohm no voice coil smell unless you clip the subwoofer I have a clip meter on my amp so when it struggles to get drive line that isn't there it shows me so I can turn it down till I upgrade to H/O alternator 200amp to make clean power these do take more than 1800 RMS if you provide a clean signal at 14.4 volts if not amp will distort and clip and voice coils on any sub burn up! I I own two of these subs only need one.

LOUD

I have one in the recommended Cu size sealed enclosure. Running a Power Acoustik lfa1 5500d class mono block with 1/0 gauge wire and a 1.2 farad capacitor. This thing hits so hard for one 12 it will blow your mind. Owned for about 1 week now with no issues so far. it handles every bit of the recommended 2200 rms. I figure I'm pushin just about that at 1 ohm from the amp

alphasonic bangs

For those seeking big bass on a low budget these are the sub compared to big named brand like Kicker Rockford Fosgate, Alpine, and MTX there's no one who will deliver such a bang for the buck great sub all around very powerful when combined with a good amp like the alpine 2000rm
