I was shocked how you went out of your way to make sure I got everything I needed and how you helped my girl place the order. She told me you were very helpful and that you walked her through step by step and answered every question she had. I give you 10 out 10 thank you Kyle at Sonic!

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 bought this to power 2 of my kicker 15's and you wont be disapointed. Fully pushed the kickers without flaw. Never overheated amp once and amp never went into protection mode. I've been using it for 2 years now. Great amp for the price and quality.

Have this powering 2 Rockford T1 15s and does an amazing job. The blue HF logo shines nice at night and is a nice addition to my blue lit component theme.

I have this amp hooked up to 2 CVR kicker 15's at 500 watt RMS a piece wired down to 1 ohm. This thing powers them like nothin and it barely even warms up, even after playin it for 30 minutes. The bass knob that comes with it is very nice and easy to install. Great Amp For The Price!!!! would definatley recommend to anybody
