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.

62.5 watts x 4 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.

125 watts x 4 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.
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

AB
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.
5
Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.

1000 watts
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.

750 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
4 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
4 ohms
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.
< 0.05%
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.
No
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-Pass (LP)
High-Pass (HP)
Full (AP)
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.

60 - 12,000 Hz
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.

30 - 250 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.
>90 dB
Channel Separation
Also referred to as crosstalk. The amount of interference on one stereo channel caused by the leaking of the other stereo channel. The higher the rating in decibels (dB), the better the Channel Separation.
>80 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 - 12 dB
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.
70A x 1 
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.
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

No
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.

I'm impressed

March 18, 2011

Owned this amp for two weeks. I was worried about buying an amp that cost so little. but I am very happy so far. I have a Pioneer DEH-P6200BT head unit. 2 jl audio c2 component in front doors. 2 jl audio speakers in rear deck, and a Sonic Sub Box: 1H12-0.7 with a
Rockford Fosgate R2D4-12. the sub was out of control until I removed it and add a little sound dampening material inside box now it is well worth the money I spent.

Crunch amp rocks!!!

February 6, 2012

I purchased this 5 channel crunch amp to replace an aging system in my ski boat. It was easy to install with 2 speakers in front, 2 speakers in the rear and a 12" subwoofer. All wiring and adjustments for sound were very easy. I was pleasantly surprised at the sound quality and levels of adjustment. The remote sub adjustment knob is a great plus. This system sounds so good that I often listen to the stereo as the boat sits in my garage. For the price, it can't be beat. I'm thinking about adding a similar set-up in my personal truck. The service from Sonic Electronics was great too.

Great amp for the $.

September 20, 2011

I bought this to save space in my Jeep since i didnt want many amps laying around. I'm a long time car audio kind of guy. MANY subs. MANY speakers. I know whats good, and whats bad.

Pros:
Good power output.
Clean Signal

Cons:
-Kind of bulky, but thats to be expected with a low priced 5 channel amp pushing this kind of power.

-Had this powering 4 kicker 75rms speakers 4 ohms. and (1) 10" 150rms 4 ohm rockford fosgate sub. I sold this system so i could get more bass when i have top and doors off on jeep. If you get this amp, i recommend good speakers (dont cheap out on them and only get 4ohm speakers) and a 2ohm sub to get that much more bass out of it. When the jeep had top and doors on, i was VERY happy with this. i just wanted more bass in the end.

Could have this amp blaring for hours on end and NEVER had an overheat problem. Even when i had it mounted in a tight, poor air circulated spot. HIGHLY recommend if you want to save space and still sound good.

Great value!

December 4, 2010

This inexpensive amp puts out excellent sounding audio for the price. I have this unit connected to four 6.5" Rockford Fosgate T1658 door speakers and a single sealed 12" Kicker CVR. Believe it or not, it is completely compatible with Kicker bass adjustment knobs, I didn't have to replace the knob that I have previously installed.

The sound quality is amazing for the price. And the wattage partitioned to sub bass is more than sufficient to shake your vehicle. My single sealed CVR wired at 2 ohms is getting more than enough juice to get it moving. Overall, I am very satisfied.

Pure Junk.

October 21, 2012

Amplifier worked fine for about 11 months, then it started conking out randomly even when not being stressed. The sound coming out of it was pretty garbage too, I forgot how much better music sounded with better quality electronics. I replaced this unit with two separate JBL amps, a 4 channel and a class D, INSTANTLY the sound was better, clearer. As if there were 15 new instruments being played in the music suddenly. Do yourself a favor, do NOT waste money on this unit, save the extra few bucks and buy a decent brand.

January 19, 2012

Great value for the price. BUT, disappointed in the sub power output. If you have a closed trunk you'll never hear/feel it. Semi-acceptable for hatchback/station wagon. Moral of the story, if you really want THUMP buy a dedicated mono amp. One downside. It is a little large.

Real good amp for the price :)

September 27, 2011

I bought this amp for my 95 Pontiac Firebird. I wanted more bass at my doors and more highs in the rear 4" speakers, also the bass channel helped alot for the Earthquake 6.5 subwoofers I have there. I will admit I didn't get the bass I wanted from my doors like my 2 channel sony amp gave me but it does power every single speaker in my car and if you count tweeters as speakers I have 8 speakers in my car. 2 twts 2 mid woofers in the doors, 6.5" subwoofers, and 4" coxial in the rear.

Perfect amplifier for a great deal.

April 11, 2011

I use this amplifier to power all of my MB Quart speakers in my 2000 Audi S4. It works like a charm. The main reason I wanted the 5-channels was to plug a subwoofer (two 1000 Watt 12" MTX Magnums) into it because of the bass gain control, but it didn't seem to produce enough power for all of my speakers and the subwoofer.
I just hooked up a second amplifier to the subs. The amplifier works great for the speakers in my car though!

Great amp at a great price

September 17, 2011

Wow, running my whole system thru this amp (5 1/4 conponents, 6x9's, and two 8" subs. The amp isn't turned up half way and it's already too much for me. Listen to music for hours at a time and she has barely gotten warm. Lots of adjustments for fine tuning your sub output. Be warned the footprint is much bigger than I had thought it would be so don't go thinking it will hide under a bucket seat. Otherwise a perfect amp for the money....

This is an awesome amp!! What I love about this amp is that you power up the whole car. It's clear & sounds great. I have 4 vehicles & they all have the Crunch P1-5000.5. You won't be disappointed!!

This amplifier exceeded my expectations by far. Its perfect for that extra thump with clear sound quality. Its perfect for a family car or someone that wants that little more sound but has a small budget. Can't beat that price!

Great amp

December 23, 2010

Installed amp 6 months ago with 2 pioneer 10's, 2 pairs of Infinity seperates + two more tweeters in an 08 F150 Super Crew, using reccomended power supply cables. No problems. Amp keeps up nicely. Friends comment on the accuracy and clairity of the sound and how LOUD it can get. I like the amp for those exact reasons also. For the price/performance/parent company, the amp is a great value. Built well.

Great Buy

February 3, 2012

I installed in a '97 Chevy Cavalier. I have 4 6-1/2" Polk and 1 12" Blaupunkt Sub and this amp hits hard. Clean power. No issues. Best buy for your buck. Owned since June 2011 and no issues. Clean, super clean power. My speakers sound like they are suppose to. Thought my Polks were bad. They are now alive. Sweet!!!

Great product, Great price

PROS; This amp is a great value for what you get. Well built. All the needed controls for various speaker setups. Fed with 1/0 gauge power and ground, with 10 gauge speaker connects will keep damping factor of the amp in very good control of rears and sub. I saddled mine with Infinity Kappa 62.9i front, 692.9i rear and Infinity Reference 860 sub in properly tuned ported enclosure in the trunk which gives superb sound all the way down to a very solid 28Hz bottom end. Properly adjusted and installed, this is the best bargain one can find in a class AB² SEPP amp. Obviously the amp has a large footprint, but realize 5 channels have to be adequately cooled, since the class of amp it is, and the heat generated by it. I would buy this amp again if I had to once again choose, and would recommend this highly to anyone looking for a very solid built, well designed AB class amplifier.

CONS; There are very few for what you pay for and get in this amp. The only thing I would have done at the design level, which would obviously raise it's price in doing so, I would have used the LM6172 (audiophile quality 3000V/µs slew rate) op-amp rather than the noisy and dirty and very slow JRC 4558D (1V/µs slew rate) in the front end of the amp. Obviously we are talking about raising this amps performance level to audiophile quality by replacing them, and I may do this when summer gets here and repost the results.

good little amp

December 29, 2011

I put this amp into a boom box for my daughters softball team. It is pushing 4 6-1/2" RF speakers and a 10" RF sub all in sealed boxes inside a large cabinet. Even at the parks in open air it carries a good kick.

Great Amp, but lacks some bass

October 19, 2010

Have a Polk MM6501 in the front, and Polk db501 in the back, and they sound really great. the problem is bass, you have to turn the bass pretty much up to get serious bass, but it then sounds like the amp is missing some watt to "control" the sub. so i have desided to get a monoblock to power my sub. the sub is a 12" Polk GNX12DVC 175W RMS 400W Peak. so i guess smaller and less power hungry sub will do fine on this amp.

Probally best amp value on the market

June 16, 2011

I can't believe how good this amp is at the price. You get all that power in 4 channels and then almost 500 peak watts in the sub. Should be enough power for the whole vehicle when powering 1 maybe 2 10" subs (You may need a separate more powerful mono amp if you really want to rock those subs). This is also Class A/B so it will sound much more warmer than traditional amps. Crunch even throws in a free Bass remote line adjuster! I heard this at the store and thought it sounded better than my alpine and its was less than half the price.
