Win the battle for great sound in your ride. Sound Ordnance amplifiers feature tough construction, rugged looks, and a 3-year warranty, so you can enjoy the full power of your music for the long haul. Even better, you can add Sound Ordnance to your arsenal at a surprisingly affordable price.

The Sound Ordnance M-1500 mono amplifier packs a 500-watt wallop that'll give your subwoofers some serious firepower. An adjustable low-pass filter and a variable bass boost allow you to control your bass barrage at will.

The M-1500 amplifier uses sophisticated power supply and output technologies to ensure clean amplification from the inputs all the way to your speakers. Special circuits protect the amp from overheating and short circuits, and a turn-on delay virtually eliminates that annoying thump when you turn your system on.

  • warranty: 3 years
  • Our 60-day money-back guarantee

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Excellent amp

Written By Anonymous, Pennsylvania on Wednesday, August 12, 2015

Crutchfield Customer Review (What's this?)

Only con is its a bit large.

Pros: Good quality for being made in China

Cons: Larger size

hot to the touch

Written By ryan, Texas on Tuesday, August 04, 2015

Crutchfield Customer Review (What's this?)

It pushes the subs and does everything i need it to; the only downside in the week of use i've gotten out of it so far is that it does tend heat up rather quickly. I haven't had it turn off on me yet but it does get warmer than i'd like it to.

Pros: cost and effeciency

Cons: how hot it gets from little use

Great deal

Crutchfield Customer Review (What's this?)

This Sound Ordnance M1500 500w amp is replacing a 12 year old Pioneer 300w that was still kickin strong. However, needed more power to my 12" as 300w is insufficient especially driving on the freeway. Size wise, its rather large but it punches my 12" a lot harder. For the money, there is no better deal right now, period.

Pros: Very affordable. Good performing. Remote bass control option. Light weight for its large size. Low pass & high pass tuning.

Cons: large size

This amp is well designed and is great addition to any set up. The low cost with the high quality makes it a great buy.

Pros: Bass knob, low cost, sturdy structure

Cons: Wire mounts are a bit small

Awesome Sound

Written By FireCracker1960, California on Wednesday, May 27, 2015

after researching woofer and amp combos I deceided that this M-1500 would be enough to push my pair of 12inch boxes and they get pushed without a doubt and then some, for your money the house brand from Crutchfield is simply Awesome, thank you Crutchfield for your quality service and selection of products, you have a customer to stay,,,

Pros: ease of connections, and of adjusting sounds to match your needs.

Cons: if there were some I never found them !

Crutchfield Customer Review (What's this?)

It has been many years since I have had a system in my vehicle. I really didn't want to break the bank and I did a lot reading. I finally pulled the trigger and ordered this amp with a Sound ordinance 12 in sub. I really just wanted this to work. I was prepared to go with another brand if it did not sound decent. So off I went with this amp and sub to my local car audio install shop for install. When I returned to pick up my car I could hear this sub filling the install bay. It was incredible. The amp did exactly what is was supposed to powered the sub with clean power! Now I can't wait for someone to ask...what kind if amp is that??....bottom different...step of the path and give these a try...your gonna feel like you unlocked a secret! Sound ordinance is the real deal!

Pros: Not like everyone else

Cons: None

Strong amp

Written By NotLarryT, South Carolina on Tuesday, April 28, 2015

Crutchfield Customer Review (What's this?)

For how inexpensive it is, it may seem sketchy but, I hooked it up to 2 MTX 12" Road Thunders. Powerful. And, the connections don't slip like the ones on my Kicker amp always does.

Pros: Inexpensive. Easy to install. Sounds great.

Cons: Scratches easily. Not personally a fan of the pancakey, flat, long, wide shape.

Works well--good value.

Crutchfield Customer Review (What's this?)

This thing really puts out the power. I have it connected to a pair of Sound Ordinance 12s and it drives them really well. I really like all of the adjustments on this unit. The one negative is that the case doesn't seem that durable. I cracked part of the plastic while mounting it.

Pros: Value, sound.

Cons: Somewhat cheap case.

Bumps to the max.

Let me start by saying that I was skeptical buying a brand I never heard of before. But my lord was I off base. This thing powers my 2x 12" subs easily.

Pros: Cheap. Powerful. Easy install.

Crutchfield Customer Review (What's this?)

Bought this to run 2 - 10" JL Audio W0 Subs (200W each) and it runs them perfectly! Pushes them nice and hard to get that great kick drum sound. And it was a third the price of just about any other 500W RMS monoblock amp.

Pros: Easy install and drives my subs perfectly! Remote bass boost dial is an added plus for when you need to tweak the sound! Great performance at a great price!

Cons: Size

Sounds Awesome!

Crutchfield Customer Review (What's this?)

Great sound and power, easy to install and adjust. Was happy to see bass boost was adjustable through a dial and not just a switch, so i could accurately adjust how much I wanted the bass boost to be

Pros: sufficient power

Cons: a little big, but still mounted fine

not bad

Written By stiggy, San Antonio on Sunday, January 11, 2015

Crutchfield Customer Review (What's this?)

Difficult to set up. Couldn't get it to thump with the filter on. Hooked it up to a Kenwood deck using the sub outputs. Need to adjust it fully so the filter doesn't counteract the deck.

Pros: Price so far. Doesn't thump as hard as my mtx sub amp that i replaced.

Cons: Directions for hooking it up. Wasn't clear how to set the amp up. The adjustable volume doesn't seem to change at all. Bought the amp for price and from the other reviews.

The M-1500 is a great amp for the price!

Paired this amp with a B-17 subwoofer, it works and sound awesome. Setting it up and installing it was fairly easy. With all the adjustments/tuning available on this amp it made it easy to run the B-17 with my factory stock system (non JBL) in my Tundra Crew Max.

Exceptional Bargain

Written By John S., State College, PA on Tuesday, November 25, 2014

Crutchfield Customer Review (What's this?)

I can't believe how much power and how many features I get for my money in this amp. I was very hesitant to buy one, because this is a no-name brand (it's Crutchfield's house brand). I researched it ahead of time, outside of Crutchfield's site, to see exactly what people thought of Sound Ordnance. The reviews elsewhere were favorable, so I took a chance. I couldn't really go wrong since Crutchfield offers a 3 year warranty on this model. What other amp company does that? No one I know of that comes even remotely close to this price range. You'd have to spend a grand or more on an amp to get that sort of warranty.

As per my wishlist, my wife purchased this for me as a birthday gift. Shipping was fast, and needless to say, I enjoyed my birthday! It came with a free amp install wiring kit. I didn't need the kit, but I did use one of the 8-gauge power cables to go from my distribution block to the amp. Nice, soft, finely-stranded, all-copper cable in that wiring kit. I have it hooked up in my car running two Alpine Type-R 8" dual voice-coil subs, with a Precision Power C.10F 10 Farad Hybrid Power Capacitor between it and my stock battery and alternator. A Pioneer DEH-80PRS and Audio Control Three.2 EQ drive the amp. Amp's sound is clean.

My install advice: this amp can get pretty warm if you run it for a long time. I ran box fans, fan speed controller, and relay for +12V remote to keep it cool. If you don't opt for that, make sure to mount it in an open area with airflow.

Pros: 1.) Tons of features! Boost adjust, line level adjust, sub-sonic filter adjust, crossover adjust, protection LED, and even a wired, remote boost dial to mount in/under your dash. You'd have to spend hundreds more to get these features in another brand. 2.) Terminals to hook up two channels of subs, even though this is a mono amp. No more piggy-backing a 2-ohm setup on the same terminals. 3.) All terminals are bare wire screw-downs, with Phillips screws. 4.) Amp has a ton of clean power.

Cons: 1.) Class A/B amp means its less efficient than most other mono-amps which are usually Class D. That means it takes more power to drive it and wastes more of that power as heat. Class A/B used to be better-sounding, but these days Class D has advanced so much that there's no audible difference between the two anymore when you're just driving subs with them. 2.) Very heavy. 3.) Very big. It took up most of my mounting location behind my 60/40 rear seat split (on the 60% side).

Great Value!!!!

Written By J. Lee, Clanton, AL on Wednesday, October 08, 2014

Crutchfield Customer Review (What's this?)

Great value but quality item. Love the bass control to allow for fine tuning of the sub. Wish it had speaker level inputs but I used a Scosche SLC-4 and it works great. Power a Kicker Sub nicely. It is larger than I anticipated but I was able to mount to the back door of a Jeep JK Unlimited.

Pros: Bass Control. Doesn't get hot.

Cons: No speaker level input

Great amp for a better price

Written By C. Tillage, Gloucester, VA on Wednesday, September 03, 2014

Recently purchased this amp to pair with the Sound Ordnance B-12 sub. Very satisfied with this combination, it bumps just as good (if not better) than many of my friends systems who have spent a lot more money on Pioneer, JL, Kenwood, etc. Would highly recommend this to someone looking for a quick and easy upgrade to your system that has the best bang for your buck.

Pros: Easy to install Looks great Lots of power

Cons: None so far!

This amp is perfect for the boost I was looking for my sub. I have a Stealth Pod encloser for my jeep, with a Kicker 40CWR 102 sub. Really thumps.

Pros: Very easy hook up, came with a 8 gauge amp wire kit, love that you can adjust all levels, and has a seperate bumed adjusting switch to locate up front with you.

Cons: A bit on the long side. For size.

Great Amplifier for the Money

Written By Taylor C, Dyersburg, TN on Tuesday, June 24, 2014

Crutchfield Customer Review (What's this?)

I bought this amp to finish a complete sound system I am building for my brother. I bought this amp for its incredible price and decent specs. I bought this amp, 2 MTX RTL10-04 10" subwoofers and a sealed Sound Ordnance box. Much much louder then I expected it to be! I was able to get all of this (including the wiring kit) from Crutchfield for under $400 with the current specials. Amazing product for the price. Only complaint is the chrome end caps on the amplifier are a cheap plastic. I wish this amp was a just a simple unflashy box instead of trying to to fashionable. After several months with the amp, I am very impressed with the performance.

Pros: Performance, Cost

Cons: Not a huge fan of the faux chrome end caps.

M-1500 Kicks BUtt

Written By lramin, Houston, TX on Sunday, June 15, 2014

Crutchfield Customer Review (What's this?)

I installed this amp to run two 12" Kicker CompVRs. It has run them flawlessly! I ran this amp for 1 1/2hours straight at 2 ohms on both 12s and although it did get hot to the touch, it never got burning hot even here in the TX heat where it got 100 deg today. It kicked all the way to the beach with me pounding on it all the way. I mean I beat this thing like nothing for that hour and a half. I wanted to see if I could "MAKE" it go into protection mode and if I did, how long and how hard would I have to beat it. Guess what, never did. So don't be scared. For the price and the Crutchfield 3 year warranty, you can't lose.

Pros: POUNDS! Sounds great! The remote controller! The adjustability. The looks. The wiring kit came free with it, can't beat that!!

Cons: Gets a little hot.

Best value out there, Great sound!

Written By Will, West Augusta VA on Thursday, May 29, 2014

I bought this amp because I had just spent $300 on 2 kicker comp 12's and an enclosure and I needed to save some money. This amp by far had the highest rms rating for the price. I was a little worried at first that the performance would match the price (you usually get what you pay for) but this amp definitely surprised me. My two subs have a combined rms rating of 1200 watts, but this little joker pounds at just 500! My rearview mirror keeps getting knocked of the windshield by the bass. As others say, it does run a little hot and doesn't have a fan, but it hasn't gone into protection mode yet. I'm no car audio professional, but it seems to have a decent amount of adjustments too (low-pass, sub-sonic, gain, bass boost) and even comes with a remote to control sub level. This is very handy for me because my head unit doesn't have a sub adjustment. Plus you get a free wiring kit. I went to Walmart previously and bought the same kit for 35 bucks before I knew better, but hey, I have an extra kit now for another vehicle. Overall, I know its not a competition amp, but it is more than enough for a beginning car audio enthusiast to experiment with and blast some tunes. Also, the amp is pretty huge for how much power it makes, but I think the size makes it kinda cool anyway, and its installed in my suburban so space is not an issue. I took off one star for issues listed in "cons".

Pros: Good sound, plenty of power, great value, looks cool, comes with remote, free wiring kit, 2-ohm minimum impedance

Cons: Runs hot, Wiring terminals are a pain to hook up, adjustment knob values are very vague, amp is hard to mount, manual is useless

Great amp for $

Written By David, New market va on Wednesday, April 30, 2014

Crutchfield Customer Review (What's this?)

You get what you pay for, this amp hits great but gets considerably hot in 2ohm mode. So far it is powering my sony xs-gs120d no prob, in a sealed box due to lack of room. It sounds amazing but i am dreading to find out if it will get too hot in the south Texas heat. I hear it runs nice and cold in 4ohm mode though.

Pros: Great sound quality and power sent to my subwoofer. Even though it gets hot it has never gone into power save mode. The 3year warranty is assuring and crutchfield has AMAZING customer service and stand behind their products. I will definitely continue to buy products from them in the future, great company.

Cons: Might not work well during summer and it is difficult to tune the amp due to the vagueness of the adjustment dials. Other than that, it is an amazing amp for the price.

The product is fine. Really good power and sound and nice features. THe proce was hundreds less than some others. I'm very happy.

Pros: Great product for the money.

Cons: I love Crutchfield and I've bought from them for decades. The problem is with the Crutchfield shipping package. It is literally a box 12 times larger than it needs to be. It was huge. It is all filled with Styrofoam peanuts and when you open the box, an electrostatic bomb goes off. The peanuts go all over the place and there are ten thousands of them. Who's going to clean this mess up? What am I supposed to do with all these styrofoam peanuts and how do I get them all up? I sent them back.

Size matters. The amp is over 15 inches long. WOW only a 500w mono block too. Could be smaller in my opinion. HOT. put it somewhere cool. Mine is in the trunk and I cant touch it after 20 minutes of play. No heat sink fins...even a small fan on it would help out a whole lot.

Pros: Does what it is intended to do.

Cons: Size/Heat/ not enough adjustments, could use a few more filters for freqs.

Great amp! Seems to have a ton of power. It brutalizes the pair of MTX 12's it's driving. Love the adjustability and remote volume knob. It does get warm though. Never had it shutdown but can't stand the volume that long to see if/when it will. The thing is huge too! 5 stars if it had easier to use cable terminals. That's it main weakness. As it is, solid 4 stars.

Pros: Tons of clean cheap power, flexibility, remote volume knob, 2 ohm stable

Cons: Huge, hot, poor access to terminals

Written By Barrack, Atlanta, GA on Tuesday, July 23, 2013

Crutchfield Customer Review (What's this?)

This amp delivers more than enough power for the average users needs, and has all the main features a proper amp should possess. I've enjoyed this amp for over a year now, and for the money, it has kicked butt for approximately $0.35/day (less than feeding a starving child!)... so, for the money, GREAT VALUE... difficult to find better SOUND PERFORMANCE vs. COST ratio.

that said...

...other factors beyond performance are important considerations for some... I saw a 2 of 5 star review from Feb 2013 from a poster (we'll call Rob, from Florida), whose assessment was 100% spot-on... just stingy w/ stars. This amp is HUGE (may become an issue if you have other amps, sub box, etc... I have little functional room remaining in a full-sized SUV). This amp gets HOTTER THAN BLAZES (you cannot hold this in bare hands more than 15 seconds or so without sustaining thermal injury). Worse yet, 30 miles into any road trip (only time I really crank up for sustained duration) it shuts down in "protective mode." In the Georgia summer heat, you look at this thing sideways, and it'll shut down (then you're the guy at the intersection singing out Katy Perry lyrics without any sound to drown out as the other motorists, pedestrians, folks at the bus stop and bums turn to see..). The connections suffice, but are CUMBERSOME... wires all over the place.

In short... all the right internal components (sound/circuitry), laid out by that science fair dweeb from high school

Pros: if sound quality and price are you're only concerns... look no further, you'd honestly be wasting your time; looks kinda cool too

Thought I would try the Sound Ordnance M-1500 since it was on sale. I am happy with this amp and it performs great! I have it putting all 500 watts to an Alpine Type R 12" subwoofer and it pounds! After a while, this amp will get a little hot, but it is nothing extreme. Overall, very happy!

Pros: great power, inexpensive, lots of functions

Cons: terminals can be a little hard to get to if you have the amp mounted low

nice thanks sales rep

Decided to take a chance on this amp, and I will buy again. Right now it's pushing 2 12" Sony XS-GTR120L no sweat. Only problem now is it hits so hard it make my CD's skip, but hey it's all good mp3's work just fine. There is one thing I would change and that is putting a passive crossover setting. because my head unit has low pass filters built in but with a little fiddling it sounds great. Installation was pretty straight forward only catch was hooking the wires to the amp but not a big deal just two allen head screws and the end slid off giving easy access to the terminals.

Pros: great value comparable to amps twice as expensive

Cons: no passive setting for the crossover. have to take end off to connect wires.

At first I was a little worried on buying this amp because I never heard anything about this company. I'm a Alpine and an Kicker man I just wanted to put something in my wife car and not brake my pockets, because she will never use its full power. So I jump out there and give it a try. I love it; great sound; there is no delay with the sound, and the look is not bad. If someone would have compare this to an Alpine or a kicker I would have laugh at them..It can hold its own weight with these other bands.

Pros: great sound; there is no delay with the sound; and the look is not bad; pick up the lows very good. has a 3yr warranty

Cons: its a little big but that is it...

Purchased this amp to go with an MTX ThunderForm and it sounds great. Was relatively easy to install but the EFX wiring kit was a necessity.

Pros: Works great! Great Price

Cons: We had to get creative on running the cabling to keep power cables away from audio cables but we made it work. I would rather see power on one side of the amp and audio on the other to make this a little easier.

This amplifier provides excellent power to my Sony Xplod 12" compact sub. Together they make some serious sound, and shake my entire King Cab Nissan Frontier. I love the remote volume control, it's quicker and easier to use than going through the menu in my receiver. It comes with both high and low pass filters which is not guaranteed in this price range. The controls are very basic and vague though. Cheap plastic dials that really only let you know if you're at the maximum or minimum. That and the large size are the only two setbacks; however in order for it to get smaller it'd have to be class D which would drastically raise the price. I am extremely satisfied with this product and would both recommend it to a friend and buy it again

Pros: Remote volume control High and low pass filter

Cons: Size Controls

On A Budget and Want Great Quality

The last sub-woofer and Amplifier i had was the B-8P powered sub. I loved the sound even more than the 2 10'' s, i have now at 500rms, and it only the B-8P was 80rms. This amp is great and a extremely budget friendly one too. Oh, and the volume remote which isn't listed is a huge bonus! I wasn't expecting one so when i received it i was in love.

Pros: Volume Remote, Loud and great for the price.

Cons: Freaking Huge for an amplifier.

Excellent Amp! One drawback

Written By TheTechGuyZ, Conway, AR on Monday, February 18, 2013

This is a great amplifier with great power options for your configuration. This amplifier puts out large amounts of clean power to your subwoofer. The amplifier is large in size but that allows the amplifier to be so affordable. The only drawback is the plastic mounting is weak and broke when I mounted it on my box. Maybe they put their money more on the internal hardware other than the plastic mounting part of the amplifier. I just moved the amp under my drivers seat but it's too large to be completely hidden. :(

Pros: Great solid amplifier that produces plenty of clean power for your subwoofer. Great quality as far as the internal hardware is concerned.

Cons: Plastic mounting bracket is weak and has a potential to break. This amp also puts out a lot of heat luckily it's like the entire amp is a thermal heat sink.

I bought this amp to Power a single Pioneer Comp 12 in a down firing box in a Chevy 1500 Extended Cab. It sounds incredible, the bass knob is nice but I don't use it, just leave it on full and make adjustments on my head unit. While it won't bounce you out of your vehicle its powerful enough to hear and FEEL the punch in any music I play which is all I want. I've had it in my truck now for two years and no issues, and I'm in my truck a lot with work. I would definitely buy this brand again.

Pros: Great Price and Value. Very Reliable

Cons: None

Meh, get something better if you can afford it.

Written By Rob, Tampa, FL on Friday, February 01, 2013

For the price, this is an okay amp, but it has some flaws. First, the dial controls are very inexact, they show two to three values and you're basically on your own to figure out what you're actually setting them to. I used a tone generator to precisely configure the low pass filter. Second, and this is a big one, is: HEAT. This thing gets so hot, running it hard (but nowhere near maxed out) for about 15 minutes made it go into protection mode because it got too hot on a day when it was about 75 degrees out. It has no fans and no external heat sinks. I have it mounted on two wood blocks so there is about 1/2 to 3/4 of an inch beneath it, and there is nothing near it. It could not be mounted more ideally. I shudder to think what will happen on 100 degree days here in Florida. So, I'm going to have to cool it with some fans, which would be MUCH better if the outside had some sort of heat sink design. Finally, where you connect the power and ground wires could be better. After putting in the cable and tightening the screws all the way the wires were still falling out. This was after applying solder to the wire too. I guess you get what you pay for.

Pros: Cheap.

Cons: Overheats easily, cheap connections, inexact controls.

Not a bad starter AMP

Written By Rick, Rosamond, CA on Wednesday, January 09, 2013

Crutchfield Customer Review (What's this?)

Bought this AMP based on the recommendation of other reviews that it paired well with the B-17 sub I purchased as a present for my son. Installation was pretty easy as I just mounted it to the box. The connections are a little trouble as they are all at an angle and inserted from the bottom of the connector. The size of the AMP is a little larger that I thought it would be which is one reason it was mounted on top of the box instead of the back or side. So far my son is please with the performance of the AMP and sub.

Pros: Looks nice, sufficient power for the B-17 sub

Cons: size makes mounting on the smaller sub boxes a challenge, angled connections can make things tricky during installation.

Great product this amp makes a huge difference compared to my old sony xplod amp. My Kicker has way more power now and pounds a whole lot harder. I love that adjustable bass knob (wired) that comes with it makes it much easier to adjust the boost when on the move. A amazing deal and I'm glad that I have purchased this amp.

Pros: Pounds hard Good looking Clean Easy Installation Deal

The product worked like a charm. I have not had any problems with it so far, Customer Service was lack luster. I waited to the wee hours of the morning to call stateside for poor service. Other than that installation was easy after I figured out what the problem was.

Pros: Easy installation, and th eproduct was just as it was stated.

Cons: Plastic holes are a pain, customer service needs improvement on time when helping the consumer (Have Patiences with troubleshooting) also needs a fan on the unit to help with cooling.
