Hifonics HFX12D4 12" 800w Car Subwoofer + Vented Sub Box +Mono Amplifier+Amp Kit

OK wire if you like red wire

I received this wire because when I bought my Image Dynamics speakers from Sonic the description said it included speaker wire in the box, but when I received them there was none. I called Sonic and they sent this wire to make up for the error. I later called Image Dynamics and found out that they no longer include speaker wire with their speakers so Sonic if you are reading this you can update your description and pictures on the ID speakers to NOT show speaker wire. For the record I bought the Image Dynamics CTX65cs and the CTX4 speaker sets. Great speakers by the way. Thanks Sonic for all your great products and sound advice, no pun intended:)

Quality Product

Works very well with my Rockford Fosgate sub system in my car.

good deal!

Pretty decent value for the price. Worked out great, thanks.

Keeps blowing me away more and more!

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!

Usable

The wiring has done me right so far but the only thing I don't like is the speaker wires. You have to carefully split it so the wire doesn't show. Other than that minor thing everything was great and a great value!

Very powerful, ,,

Was hesitate to buy this,, glad I did hook up to a mofo 12, and re 10, I have 1/0 gauge from battery to cap then 4 gauge to amp,, I love it,, lights still go dim,, need extra battery it love power,, removed my crossfire xp1400d,, this is way better,,,,

Just purchased

I just bought this, and installed it in my 2000 accord. Don't be fooled by the price, this thing kicks. I hooked it up to my Pioneer GM-5500T amp putting out around 400 watts RMS. This sub sounds great so far.

price is right

the price is right for this setup. the ground wire and the power wire are to big for my amp but i made them fit. better to have to much than not enough so if i upgrade to a larger amp it will be fine.

Nice sub

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

Hifonics HFX1204

These subwoofers really hit hard for the price. Probably one of the best I have ever bought. We'll see how long they last.
