Hifonics HFX12D4

I've been a car system fan for many years and had alot of setups. These Hifonics Subs are more than you can ever expect from a low priced subwoofer like this one. If you are looking for a setup of two or more speakers these are the best. Great looking, powerful, CHEAP(money wise) and built to last. I have 3 of them and let me tell you they hit so hard my ears ring. Oh yea one more thing Sonic Electronix - a super glue should come with these subs cuz my rear view mirror fell right off. :)) That should tell you (buyers) that these product is worth of money. Thanks for reading this hope I helped.

Sounds looks and is a great sub. Best for the money.

This sub just keeps hitting harder and lower! I'm amazed and blown away! I was underwhelmed for a while there because I realized that I actually killed my previous sub by sending a very strong and very clipped signal to it by having the gain set too high for my head unit's preamp voltage. To reach the ~250W RMS the amp is rated for with my head unit, I need the gain knob LESS than half way up. Any more than that and it starts distorting, and this is not because of the sub but because I'M SENDING A CLIPPED SIGNAL FROM MY AMP. I feel like I've officially made that step from n00b to experienced installer. I had read all the instructions and guides before and never understood what they meant by matching the head unit's preamp voltage. Now I do and I know how not to kill a sub (and/or amp, for that matter).



Anyway, I had never broken in a sub and this sub is STILL blowing me away! It's hitting harder and it does better throughout the entire range. The lower notes (centered in the mid to high 30Hz range) I could barely feel at the start are now making the car have a slow, deep vibration when they hit (remember it's a sealed box). Being a 400W sub I feel like playing it full-blast at 250W RMS is good enough as 'breaking it in' and it is just finally beginning to impress me. It's hitting almost as hard as the Memphis sub that was getting a clipped signal with a few extra watts to compensate for my bass-trap trunk (thick leather seats, kills any bass trying to come from right behind you). Right now I'm keeping my rear seat's backrest down so I can feel the full effect of the sub.



I just can't wait to give it 400W. OMG. What a great sub. If 'you get what you pay for' is true 99% of the time, the HFX12D4 is the 1%, by far!

Great subwoofers for the cost cant beat it. sounds good, hits hard just all around good quality.

For the price they are the best on the market I think there around $** now. These sub have and amazing sound and clarity for what it is but it can only handle about 500watts as a pair as I had them.but if your on a budget get them
