HFi Retro Style, Advanced Technologies

The HFi2500D 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 HFi2500D – get yours today!

Power

I have one of these amps hooked up to a rockford fosgate t2 and it bumps. it pushed out clean bass and will set off car alarms a distance away. The amp never gets hot and is vary hungry for power so I used 0 gauge wire. Haven't hade any problems with it yet. you will not be disappointed. Good amp.

okay

I just got it in today and its okay but if u buy be ready to spend $300+ in accesories. I needed a battery to get enough power to run it plus the 0 gauge amp kit 200 dollars. This takes a lot of power but other than that no problems for right now only had for a day so dont take me too serious

good amp

I'm pushing 1 fi btl 18 in 5.5 cubic box tuned to 20 Hz and this amp doesn't even flinch. If your going to run this amp to its full power. You need two batteries 0 gauge wire and a alternator capable of putting out 250 to 300 amps and you want 14.5 to15 volts. Very power Hungry amp.

Ok amps

I just bought 2 of these amps and have each running 12 inch Solo X in a ported box. I'm not to impressed with these amps or the Solo X's . I had to L7s on a Hifonics 1000 and it hit almost as hard as the two Hifonics on the solos. Maybe the subs just need more breaking in ? O and by the way the solos have a barn yard smell ?. Not sure what that is.

This amp is awsome

I bought this amp from Sonic about 5 months ago and it's the best amp I have ever owned. I havent had any heat issues and i have been using it in 90 to 100 degree weather...this amp will do rated power @ 14.4...i have it on 3 alpine type r 1222d's @ 1.34 ohms....this amp is a Beast and it is power hungry..proper electrical system is a must to make this amp really shine...Bottom line...You wont be disappointed!!!

this amp rocks!

I bought this amp a few months ago and im using it on 2 12" L7's (dvc 4 ohm) ran in parallel @ 1 ohm with the gain all the way down (as it should be) and the bass boost at about half way in my truck and you wouldn't believe how hard my subs pound!! the hifonics have always had great amps, they run cool, they can be bought at a great price, and give an insane amount of power. they are even used and recommended by the pros, can't go wrong with that, so i recommend this amp to anyone looking for raw power for their system BUT be sure to make upgrades or you'll kill your alternator like i did lol.
