Great Price for the performance

I purchased this amplifier because I have heard a lot of positive reviews of hifonics amps saying they never let you down, so I decided to give them a shot. From the get go as soon as I got the box the whole image was very intimidating with the box saying "power from the gods" and I was very pleased with the overall design and appearance of the amp itself. The bass knob has a light-up ring which is eye candy at night, and if it goes into shut off mode the ring turns red. I am using it for my 15" Kicker l7 in a 5 cubic feet box and it pushes it HARD. I am using it in my 1999 v6 mustang and I finally got it to flex the windshield a bit and it hits lows like a champ. The only downside I have for this amp is that it does not like the heat and will overheat if there is no proper ventilation.

Excellent product

I was looking for a good amp at a reasonable price to power my Rockford Fosgate T1, and came across this amp. Very easy to adjust and works excellent. I have it ran at 1800w on 1 ohm and it sounds amazing, crystal clear with no issues. Would recommend to anyone and would buy again.

Great price

My husband is completely satisfied. He was so excited when he received his order. He was so happy that he was like a child in a candy store. He couldn't ripped the box faster. He said it was easy to install and overall love the performance that he wanted. I literally could hear him from the next block. He said he likes it loud and obnoxious.

Love this amp

I loved this amp. hands down my fave amp that I have got in sometime.. The heat syc is super good. I drove 5hrs straight with the music to the max with the bass bosst/gain all the way up and the amp did not go off at all. I also had it the full 1800watts!! To bad someone broke in my car and took it. Will be getting 2 this time around!

Good bang for the buck

Hifonics is power hungry, put this on 2 alpine 12" on a 2015 cummins and it still dimmed the light towards the top end. ended up getting a cap to take some stress off. i would suggest getting a few hundred watts over your total RMS, last hifonics i had would go into protect mode with it hit the low notes on 2 15"

great product

I am really happy with my purchase because I'm from the old school and when I was younger I only used Hifonics amps in my cars and its nice to see they still give you the type of quality power you need to get the right boom from your speakers and at a reasonable price..
