Orion HCCA Series HCCA2000.5 High Performance 2000W RMS 5-Channel Class AB/D Amplifier - 1 Ohm Stable, Low/High Pass Crossover, Bass Boost Control, MOSFET Power Supply, with Bass Knob, Made in Korea

I must say this is the 2nd Orion Amplifier I have purchased, The first being an OrionXtr2500.1Dz which was a gift from my wife. I decided for once in my life I wanted an amplifier for my mids & highs that could handle the amount of speakers I usually have installed. I usually have anywhere from 4 pairs to 6 (pairs) of 6.5" and 6x9" speakers. All my amps in the past would have a hard time giving the power needed and I would usually end up with a wiring frenzy to keep the amp at a sustainable impedance. This amp. The Orion HCCA 1500.4 has outdone itself, seriously. I have 10 6.5" speakers in my vehicle along with 6 12" subwoofers. Its hard to keep your vocals loud enough to hear with that many Subs. The Orion HCCA1500.4 has my system sooo loud I've had people run from my vehicle. Hand to god. The amplifier has barely gotten even warm to the touch after playing for hours straight. I went ahead and installed 2 12v fans to help keep my subwoofer amps cool and with those 2 little fans added on the other side of the vehicle from where the Orion is, that amp stays Ice cold all day long. And it can be used for subs as well putting out great clean Rms power across all channels. 4ohm- 4 x 250w Rms, 2ohm- 4 x375w Rms, 4ohm bridged- 2 x 750w Rms. That's 375 watts per channel Rms by 4 channels. Or 750 watts Rms per channel for 2 channels. Awesome amp. Hands down.

This things is a beast. Upgraded 2022 Version. I suggest battery bank , XS Power Batteries, Upgraded Mechman Alternator with the Big 3 wire Upgrade. Power her right and she will pound SPL. Sound Pressure Level. Not just herd. People Feel this type of bass

Best amp hands down. 3000rms more like 10000rms orion always under rated. Buy it. You will not be disappointed!!! Need good electrical system tho. I have 2 300amp alt and 2 100 amp hr lipo (battle born) 15.0volts all day no light dim at near full tilt.

This amplifier is huge and heavy. You can tell it is top quality. I might add they really do under rate their amplifiers, this thing pushes way more than rated. GREAT JOB ORION!

I bought this to replace my Taramps Smart 3k. This amplifier is so much more powerful. With 3-0gauge power/ground inputs. I'm running at 3k @ 1 Ohm. It can do twice its power rating at .5 Ohms. Lithium Headway Bank and 300 Amp alternator. This thing uses a lot of power. Can't wait to meter it tomorrow. I was doing a 144.38 on the smart 3k. I will also be adding a second orion hcca 122 soon. I will update.
