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.

75 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.

100 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.

200 watts x 2 channels

Power Specifications - Full Range Channels

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.

D
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.
4
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.

800 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.

400 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.
0.06%
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.
Yes
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
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)
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.

40 - 500 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.

40 - 500 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/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.
No
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.
40A 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.

Yes
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.

Bought the GM-D9500F

February 25, 2012

This amplifier met my expectations. Although my previous amps where very good brands and AB type, this D type unit performs very good and offers more power than AB´s in a smaller package. The D type amp supposed increased distortion has not been noticeable in my installation. I definitely recommend this product and recommend Sonic Electronix.

An excellent out of the box, plug-n-play kind of amp. Very compact, stealthy. It's sturdy, durable and you can easily swear on its build quality. Above all, looks good too. Performance? Well, I used a couple of amps and this one didn't need any kinda tweaking, as if it just understands what speakers it has to drive.

Great Amp

November 16, 2010

I have this amp installed with a Pioneer double din 4200. I have two sets of the Infinity Kappa Components. The sound is incredible. I had each wired to one channel, but the amp is REALLY under rated. I already blew two sets. Luckily there were replace by Infinity. Now I have a set wired to one channel so I am only using two channels and they still sound great at only half the gain.

Good value amplifier!

February 19, 2010

This amp has a great sound, small footprint, and low energy consumption (class D "digital" amp). It is a no frills amplifier that puts all its power into sound (not flashy lights and other bells and whistles). This amp is a great value for the money. The highs could be a little more clear, but for the price I don't think there's a better digital 4-channel amp on the market. Pioneer did a great job with this one.

Since it's a new amp, I can only guess on its durability based on Pioneer's track record.

The only downside I can see is that the amp has the "old style" connections for power, ground and speakers, not the newer, more convenient allen wrench connections. Presumably this was done by Pioneer to save money, passing the savings on to the consumer. That, with some lack of definition in the high end, is the only reason I ranked it "4" instead of "5". In actuality, I'd rank it "4.5" if this were an option.

The amp they sold me really packs a punch its small compact size fits perfectly in my car. Another place tried to sell me a amp i didnt need even my instaler i brought it to tried to tell me what they sold me was no good, but the installer who was doing my car told me not to let them talk me into sending it back. That the stuff i bought from sonic would destroy what they had to offer. I will deff recommend sonic to everyone i know

Big performance, small package

February 20, 2012

If you have space or power requirement considerations, this amp is the solution. It draws less current than comparable output amps, and is small enough to fit in tight spaces. Very clean sound, adequate power to drive 4, 2 ohm speakers, nicely overcomes road and exhaust noise in my Corvette convertible at highway speeds with the top down. Great value.

Great Amp in a Small Package

December 7, 2011

This amp replaced a much older, larger, and less powerful Pioneer 4-channel model I had been using. I continue to use 2 channels to power my front (component) speakers, and bridge the other two channels for a trunk mounted sub in my 09 Civic Si.

Another advantage is how much cooler it runs. This isn't really a requirement for me due to where I've mounted it, but for those that are considering mounting in a confined space like behind or under a seat, it could avoid a melt down (had that problem with a Sony amp).

It took a while to "balance out" the gain and high/low pass filters for optimal sound and performance, but I'm really pleased with the results.

Love. Pioneer. Amps.

August 12, 2011

Currently running four 3-ohm components on the front channels and two 2-ohm 6x9s on the rear, so I'm drawing every last watt out of this amp. Amp pushes them all flawlessly without any distortion, and it's in a Suburban so I often use every last watt ;) Would only trade this amp for a more powerful Pioneer, but I don't think I'll ever have to (even in my Suburban!).

Great Amp!

June 24, 2011

Its small footprint and powerful output made this a no brainer for me in my MR2 as space is kinda like New York and at a premium. I built a small MDF shelf for this to mount to behind my drivers seat and ran all cables through the firewall and poked them out behind the amp for a clean install. It powers my 6" components and a 10" sub to perfection and still keeps its cool. I have a Rockford Fosgate 8 GA. amp kit feeding it and so far its been great.

Highly recommended!

Only one "negative" thing...

February 7, 2011

The only negative comment I have was that when I went to pull back off my Monster cable 4-ch RCA low-level input cable... one of them didn't want to let go of the female connector on the amp... and it ended-up pulling the outer sheath of the female RCA connector off from the amp itself! I carefully re-inserted this female connectors two prongs back into the holes they came out of and it seams to work ok. I'm kinda stunned that this piece wasn't better fastened into the unit itself. However, later-on in talking with tech support some other day calling about something else I mentioned this happened and they told me that with the Monster Cable RCA's you have to twist them while pulling them back off. Because of the way they are designed.

Jeep TJ Amp

December 27, 2010

Perfect for powering your 4 front speakers in a Jeep TJ (Dash + Sound Bar). You need to replace your factory speakers to something with 60-75 W RMS power. The highs and mids will be crystal clear. You can't get much bass out of the front 4 speakers even with this amp. The Jeep's 4 speaker locations are not condusive to making much bass. You need to add a bazooka bass tube for great bass if you want it in a small space package. There are other options for more bass but none with bazooka ease and clean sound for the buck. Installation on this amp was easy. I have never installed an amp and was able to do it with prep work and about 5 hours. It will be faster next time.

Works Great at 2 OHMS!!

September 20, 2010

I purchased this amp to run my Alpine 6.5 separates. I have 4 pair so the amp is running at 2 ohms. This amp has great SQ. (I couldn't tell the difference between the Alpine it replaced) The Alpine was just too underpowered. This amp gets very loud even at 2 ohms and its never turned off on me. But I have it wired properly. 4ga. Anyway this amp is a very good deal for the power and SQ you get.

Great power, great price!

October 24, 2012

Powers a JL 150w 6 1/2" Sub, and Infinity Perfect 6.1 components.

For the price I paid, this amp is by far the clear winner, unless you want to pay an additional $200 for a newer set of connectors and possibly a slightly higher output.

I personally think this amp has been under rated as it has no trouble supplying the power to the speakers and sub.

Profile of the amp is small, not quite small enough to fit under my MR2 Rev. 2 seats without trimming the carpet, but would easily fit under a station wagon seat or Corolla.

Well worth the investment if you're not sponsored or have $1,000,000.

great little amp

November 29, 2011

I’m using this amp to power a set of pioneer 5-1/4 component speakers in the front and a set of pioneer 6 x 8 three way speakers in the rear door of an 02 Ford Escape. Overall, I am pretty happy with its performance alongside a powered 10" sub. I don’t know how it would sound without the sub or if you powered a sub off it too. It is a great fit, out of the way in the cargo area of my SUV. Seems pretty durable too. I was moving a large metal chair that had shifted and hit the amp pretty hard. It put a little gouge in it but no other noticable damage.

One issue I have had is when I connect my ipod to my pioneer head unit, there is a very low but noticeable white noise. Like the sound when you (use to) start a cassette tape. I can’t think of any other explanation. It may be the cable, head unit or my crappy older ipod but I didn’t notice the noise until I had the amp in. I have had a little trouble tunning amp to my speakers but only because I mostly don't know how. I am a diy'er and don't like paying people. I think I got it pretty close to its best sound. Again, that's according to my ears. All in all, this was a great upgrade to my sound system that sounds great to me. Very clear and balance sound.

November 11, 2011

I purchased this amp because my kicker amp got shorted out while working on the truck. So i didnt want to spend a fortune again for another kicker. Figured for the price i would give it a try. Well i cant believe im saying this, but it blows my kicker out of the water. (and all i run is kicker) This pushes my kicker 6x9's outstandingly. And it stays ice cold. No hiss or distortion what so ever. So after this great experience i gave my kicker sub amp to my son and purchased the pioneer D mono block amp. And it is just as fantastic. My other amps cost double or triple the price of these pioneer digital amps and i have to say the pioneers are much better. Anyways what a great product ( VALUE-SQ ) Buy these new digital series amps and you wont be disapointed. WELL DONE PIONEER

August 21, 2011

This is the third attempt at putting an amp in my KIA Sedona sight un-seen system. First one was a US Amps XT800. I guess the cycle their amp models every few months, a odd little company. customer service was not very helpfull. Second amp was a BAMF 1200/4 failed in about 24 hours, Now dealing with a crappy return policy with manufacturer.

Third is the Pioneer GM-D9500F. the only issue with this amp is the old school terminals for the power connections. Crimping 4awg is not the easiest thing in the world for most DIY'ers. But, it is a good amp. compact, low temps, Good power. I hope it lasts...

I've had this product installed in my truck for 6 months now and it has been just great. I have one 10 inch alpine on two channels bridged together and two alpine 6x8 speakers on the other two channels. This amp has done everything i wanted it to do and more!

If you are looking to get some nice door speakers and need more power than your head unit can provide, this amp should do the trick.

My best advice is to pair this amp with the best speakers that Sonic's advisers feel will work the best. They have not failed me yet.

SQ Amp, Cheap price!!!

May 11, 2011

First of all, I'm not a kid that like Boomin' system, I'm a car audio installer that love sound quality over sound quantity (althought I like to crank it up if the systeme allows it)...

That being said, I,m a former owner of an Alpine MRP-F300 and switched to the Pioneer GM-D9500F pretty much 'cauz I like to try stuff just for fun... OMFG! I immediatly heard a big difference in sound quality AND quantity! Never gets hot, never clipped, small footprint, and power to spare! Extremelly satified for a year now! Better amp you can get for that kind of price (or even double the price for that matter...)

You'll never go wrong whit Pioneer product, you always get what you paidfor and more!!!

Good Value Amp

October 4, 2010

Have this amp hooked up to two pairs of Alpine SPS-600C speakers. It does a good job of pushing the speakers. Doesn't take up a lot of room so it can be mounted almost anywhere. It does get a little warm, but nothing to worry about. As always great shopping experience with Sonic.

Not as advertised!

August 10, 2010

I purchased this amp in the expectation of it being able to drive 2 ohm speakers and it could not! It may very well be able to drive 4 ohm speakers but I was going by the info published by the manufacturer and I was very disappointed. I could get nothing but low volume out of it no matter where I set the gains. It would cut out via the protection circuitry at even a moderate listening level. Great size and small footprint for tight applications but don't expect to drive 2 ohm loads with this amp!

What a great amp! Took a chance with it cause I wanted the class D and I couldn't be happier. Great sound (best of all) but also little heat and small size fits under the passenger seat. This thing really rocks my Z28, even with the t-tops off. Can't imagine too much better for the price. Really makes my Polks sing!!!

I purched this amp for the size and it being a D class amp. I am happy with the sound and the power.

The only down side is the old style power/GND/SPKR connecters. Although it is really not that big of a deal, it detracts from the looks of the amp.

I installed this amp on my 25 foot fishing boat to power 8 coaxial 8" spaekers, and it sounds great. It is loud when out at the sandbar, and sounds great when you are going 40 mph on the water.

Audio System Revived

June 25, 2012

My stock 2003 Ford Ranger Edge system was not doing it for me anymore so I opted to get a single DIN Pioneer Stereo, this Pioneer amp, 6x8 Pioneer Speakers, and Kicker wiring. I am so pleased with the performance of this amp that I will be looking for pioneer parts when adding a small sub setup to the truck. In 4 channel mode this amp lets the truck be extremely loud and sound very crisp for tailgate parties and everything.

Using this to drive 4 Infinity Kappa 63.9i off the factory head. I've had several audiophile and musicians in my car and they want the me to do the same setup for them. The amp is small and packs a lot of power.

Very amazed

March 1, 2012

Originally I purchased this amp to power the four polk 5x7's in my wife's Mazda 5. There's really no were to place an amp so I ended up putting it in a storage compartment under one of the center row seats. I was pretty worried about it overheating in such a small space (only enough room for the amp) but every time I checked it was never warmer than ambient. It performed very well providing great sound at all volume levels. I never experienced any issues.

We ended up selling the 5 and bought a Town & Country. Turns out there is even less space to place an amp in a larger vehicle so the amp is nestled under the drivers seat. This time it's powering four Infiinity 6x9's. We'd been running these speakers off the head unit for about 3 months and weren't very impressed. They sounded better than stock but didn't have the rich full sound we wanted. After installing this amp I'm reconsidering putting subs in the van. The highs are amazing and there's is more than enough bass to rattle everything in the van. This was probably the best money I have spent for my stereo.

Very Happy with install and sound

September 12, 2011

I bought this Amp to fit into a Mini Cooper. Compactness was important, full marks there. It runs cool in the boot mounted on the side. Easy to hook up to power and to the Head Unit with either Speaker outs or preamp and it figures it out for you. Automatic turn on.

I drives 4 Pioneer speaker sets which respond to an honest 30 hz with no sub woofer. The bass is deep and strong enough to make the car shake and rattle.

I like good sound, my home stereo is audiophile grade (vinyl rules) and this does not disappoint. I would need a better Head unit to really see the limits here, so maybe later.

July 20, 2011

This amp is perfect! I have it mounted behind the rear seat in my truck and it fits perfectly... I use this amp to power a pair of Alpine SPS-619 and a pair of SPS-609 all at 4 Ohms.

The sound output is over the top amazing and very clear. The connector's on the side of the amp being the "screw type" are no issue what so ever. Go out and buy some "fork" style crimp connectors and problem solved.

The fact that this amp is 2 Ohm stable means I can upgrade my speakers later and not have to upgrade the amp. I've had my system playing at full power for a 2.5 hour drive and not a single issue with the amps (both Pioneer; GM-D9500F and the GM-D8500M).

This is a very well designed amp and it has a very classy look to it. If I had to buy another 4-channel amp in the future with these specs I will buy another Pioneer.

March 29, 2011

This is a great amp. Its small for the power it puts out. And it puts out a solid 75 RMS watts per channel. I have it powering 4 sets of Alpine Type R 6.5 components and it sounds great. Every bit as good as the Alpine amp that it replaced. The amp barely gets warm to the touch also. Overall, I would recomend this amp to anyone. Even an audiophile like myself that is all about SQ.

This amp had exactly the features I wanted at a great price. The best thing about it is that it keeps cool enough and is small enough that I was able to install it behind a plastic panel for a completely stealth install. The power this amp puts out is clean and crystal clear, though some of the midrange has a tiny bit of a "grittiness" to it, but this is to be expected from a full range class D amp.

All about the sound

July 19, 2012

Every amp I put under my seat got hot enough to fry an egg when I pushed it. Even low volume the others (class A/B) would get hot.

This is my first class D for my mids & highs. This amp gets warm normal playing and I managed to get it hot when pushed to extreme. There was a difference of less heat, but for class D I was hoping for cooler.

Now for the sound:
I had four other amps for my front in the past and they all had slightly different sound signature. This one is no different. I would say the low level resolution is slightly exaggerated, while also somewhat of a boost or extension past the upper highs. This creates a sound that, to me is best described as very "high polished" and "shiny." The only drawback is the depth of field is not as deep as I have heard elsewhere, but the sense of "shiny, polished" clarity is impressive nonetheless.

Also, it does not have either the sweet "MOSFET" sound, nor does it have the dry "bipolar transistor" sound. Its sound is unique and of its own, and never harsh when driven hard, just a lil' "glassy" at max volumes. This lil amp blew FOUR OF MY INFINITY SPEAKERS! Both tweeters first, then woofers, as they were all 2-way 5x7 speakers, and they were only pushing the kids/highs. The amp would shut volume down into protection just "after" it burned them!

I was going to upgrade to the "Kappa Four" amp to see if I liked the sound, as I prefer a sweeter "MOSFET" sound than this, but I found a better speaker match than the Infinity, which are too brittle sounding in details and blew out. With my new speakers, the sound is more natural in upper mids to highs, and just right without blowing out like the Infinitys and almost half the price! They are the "Precision Power PPI PC.572" 5x7 2-ways at 3 ohms. Also with external crossovers just like my Infinity Kappa I blew! So, I will keep this setup until something dies!

I have this amplifier and just recently noticed that it's rated at 800x1 max power. I've been running a set of mbquart components on the front channels, and bridging the rear channels for the sub, but 200 watts rms is not enough for this sub(polk mm1040). How can I wire the sub so it receives the full 800 watts(400 watts rms, I'm assuming) Please help??
William T on Jan 1, 2015
Best Answer: Hello William,

Unfortunately, there is no such thing as wiring an subwoofer/amp in a specific way so it can provide more power. You are obligated to the restriction/parameters of the setup. Assuming it is currently wired properly, you have reached the full potential of your setup. The 800w you are referring to is the MAX power, so its not an obtainable figure. We suggest getting into a Monoblock, for just the subwoofer, to get the ~350/400w RMS that the MM1040 is asking for.
