HFi Retro Style, Advanced Technologies

The HFi1000D complements any application for your subwoofers. Today’s high output subwoofers require only the finest, dedicated power to run loud and constantly in any vehicle. The HFi Monoblock series of amplifiers meets these expectations and will gladly get your system that extra bass you’re looking for.

Incorporating Class D circuitry to allow for dedicated, efficient power allows for higher bass response, and not sacrificing any sound pressure. Why neglect your subwoofer of the high power output it truly demands? The HFi Class D Monoblocks are affordable, extremely powerful, and designed with a pleasantly small chassis. This allows the high power output amplifiers to take up the least amount of space in any installation.

The included bass knob can allow you to adjust your bass to match any music type, and allows you to replicate your bass to compliment any genre type. Integrating the Pulse Width Modulated MOSFET power supply to allow for efficiency on your car battery allows this amplifier to put out impressive power without drawing too much from your car’s electrical system. Value is truly defined with HFi1000D – get yours today!

I have a Chevy Astro van it's hard to get speakers to thump in that big of an area. But my Hifonics amp with my two 12s, Boss speakers, really do the job. I love the quality sound i get with them. Thanks.

Bought this amp to power a 12' mtx t9500 that my friend gave me i was a bit disappointed in myself my friend told me to buy a 2000 watt amp i bought this it barelly powered my sub cause i ordered the wrong amp. But this amp still banged like crazy in my truck i would recommend this amp to anyone on a budget and wants to get crazy loud bass. I myself returned it for the 1500.1d wich is what i should have bought but didnt listen. My bad. But Sonic Electronix exchanged it for the other one after paying the difference this is my 6th purchase from them never had any regrets. I love Sonic Electronix
