Overrated

says it handles 600 watts but dont trust it. half power on my Hifonics HFi1000D and it over heated and died. i would recommend you spend a little more money for a better sub if you truly want 600 watts


**Note From Sonic: When overpowering woofers keep in mind to tune your system to compensate for the additional power. HFi1000D can push a true 700W+ at 2 Ohms which is a little more power than you want to constantly push into this sub, especially with high gains or bass boost.**

Excellent bass for reasonable budget

I have 2 of these in a sealed box with a 1500 watt RMS Hifi amp and they handle it fine even with the bass turned up. Have not had a single problem with this setup. Anyone who says these are not good subs is terribly mislead. obviously there are bigger and louder subs, but if you are on a budget, I highly recommend these subs, Hifonics is an industry leader in several aspects of good sound, and these prove it day after day of use.

amp too strong?

I bought one of these about two weeks ago and its just as loud as two Audiobahns I had before. But I think I need to get two more because my amp has the voice coils burning after a song. I have a Clarion dpx11500 class d mono block. I think the amp may be too strong?

pretty good

These are my second pair. I have them in my 2003 Chevy silverado extended cab in 2 down-firing subwoofer boxes. They sound decent in there considering small amount of airspace. In my 1995 suburban they were ridiculous with a hiphonics brutus2006 which toasted them but while it was working it pounded too much

Pretty Good Sub

Well, I have 1 of these hooked up to a Sony XM-ZZR3301, which is giving it 600w rms. To be honest, when I first hooked it up, I was a little disappointed because it was not getting as loud as I thought it would, but after a few weeks of breaking it in, it did seem to get a bit louder. So overall, I'm pretty pleased. This sub will hit a wide range of notes, I was surprised at some of the low notes it could hit. And if you turn up the volume, it will get loud. I would recommend this sub to anyone, although I would probably recommend getting 2 if you have the space/money, unfortunately I was on a tight budget.

Nice Bass-Great Price

I would definitely recommend this sub to anyone who likes power and clarity. I got this hooked to the hifonics 2000D at 2ohms, great bass cant beat it.

preety good

Right now I have one sub on a weak amp that's only pushing around 300 watts and my cousin can hear me coming from 2 blocks away. So its a really good sub for the price. If u get a good amp and a pro box this sub will hit hard. To be honest if u can afford a square sub u should get it but if not, trust me if u hook this sub up the right way it can out bump alot of subs at the same price. I even wooped two kickers already with this one sub lol so just get the right stuff and go out beatin
