Power Specifications - Full Range Channels

RMS Power @ 4 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

550 watts x 1 channels
RMS Power @ 2 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

RMS Power @ 1 ohm

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 1 ohm, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

1600 watts x 1 channels
Bridged RMS Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the RMS power created once an amplifier is bridged.

Peak Power @ 4 ohms
This form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage occurring. Often times this maximum is achieved during a brief musical burst, such as a drum accent, or low bass hit.

Some manufacturers display peak power ratings on the face of their products to increase the appeal to consumers. The RMS power rating is more accurate, and we recommend using it for product comparison. However, some manufacture's do not provide an RMS figure and therefore one cannot be advertised.

Amplifier Specifications

Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
1 - Mono
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

1600 watts
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
1 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Not Bridgeable
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
0.08%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
No
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
1 pair
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

None
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

35 - 250 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
15 - 35 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
95 dB
Bass Boost
The objective of the bass boost is to get more kick out of your subwoofer. It is a circuit that emphasizes the lower frequencies at a given point. The bass boost should always be set first before setting the gain. This feature is known for destroying subwoofers and is commonly used incorrectly, so be cautious.
0 - 18 dB @ 45 Hz
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Yes
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
80A x 2 
Strappable
Some amplifiers can be "strapped" together in order to increase the output of a single audio channel. These amplifiers feature RCA preamp outputs, allowing you to pass the signal directly from one amp to the other to ensure consistency.
Sonic Certified Amplifier
Sonic Certified amplifiers have been tested by the experts at Sonic Electronix to meet or exceed the wattage ratings provided by the manufacturer. If this is marked as Yes, then you can trust the wattage ratings. If marked as No, then we have tested the amplifier and it did not meet the advertised wattage ratings. If marked as Not Tested, then the Sonic Electronix experts have not yet been able to test the amp.
Amp Bluetooth Connectivity
This feature will tell you if the amplifier has the capability to connect to a Bluetooth device.
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

February 17, 2006

First of all let me say what a great deal this amp is . I have two 12 in. kicker L7's I had a kicker 550watt amp which I paid 380 buck,and still was not doing the job, the guy at the audio dealer told me I would have to pay 700 buck for a 1200 mono amp that would get the job done. So I left , a friend told me about Hifonics so I checked it out. I picked up the BX1605D;when they gave me my car back after the install let me say I could not sit in my own car. The sound was nice a clear and still the bass hit hard I never knew it would loud like that. This amp is the best buy ever you get your money worth and a whole lot more. If you want competition sound on a student budget the Hifonics BX1605D is the way to go

Hifonics BX1605D

September 10, 2005

I'm running two 10" Alpine Type R DVC's with this amp. I initially hooked it up for a four ohm load and was disappointed with the results. I rewired the subs for a one ohm load and after some fine tuning I'm more than satisfied with the way they hit. I have my amps on a rack in my spare tire compartment and I noticed the BX1605D was getting hot to the touch. It did not go into protect though. I installed a fan the other day and that seemed to make a difference. For someone on a budget this is a pretty good amplifier. One other note, the controls on this amp suck if it's in a hard to reach position. You have to get a small flathead screwdriver to adjust it and even with that it's difficult.

hifonics bx1605d versus profile ca800

March 16, 2005

I just ordered the hifonics bx 1605d amplifier. I was currently running the profile ca800. I purchased the hifonics because I needed an amp stable to 1 ohm. Current sub is an atlas 15" wired for 4 ohm load.

hifonics rates the 1605d @ 550 rms into a 4 ohm load, profile is 600 rms into the same load. Gains were set properly, everything turned down, no bass boost, no gain. turned the h/u up to 3/4 volume, (just before distortion) then turned up the gain. (just before distortion)

The hifonics sounds NOTHING like my 60 dollar profile amp! All the people who've heard the hifonics cannot believe the difference in diminished output! YES thats right DIMINISHED OUTPUT!!!

I didnt use bass boost on either amp, and all settings are flat. I checked to see if the speakers are in phase, (they are) but still the hifonics is not as loud as the profile. Does 50 watts rms make that much of a difference? I dont think so. The amp was professionally installed. All wiring under the hood is 4 gauge, I have stock alternator with a deep cycle blue top battery under the hood.

I hope when I go to the 1 ohm sub, (avalanch 18") I get better performance, if not I WILL BE SELLING THIS AMP and SOON!

BX1605D

September 27, 2005

I have a friend with one of these hooked up to 2 15" L5's and it has more than enough power to push them... These amplifiers are known to be more efficient now that they are underneath Maxxsonics... These amps are well worth the price of them and then some... I just ordered this amp also to push my PBX 15 and it should fit real nice... plus you got to love the 1 year warranty, just in case, not really gonna need it with this amp tho... and the adjustments are just what you need for sub applications, what else could you ask for??? It is made for a screw driver, but you can just adjust it with you finger if you wanted to... overall... best bang for the buck!!!

Sweet Amp

July 26, 2005

This is an AWESOME amp for the buck. I got a 15" sub and a 5 farad capacitor to go with it. She really pushes the hell out of this single 15" sub which is pusheing out 1100 @ 2 ohms. My friend who has been installing systems for years told me that a 15" sub would sound muddy in my trunk, but when he listened to it he was amazed.
EXCELLENT AMP Highly recomended.
