Our take on the Sound Ordnance M-2250 by Crutchfield's Buck Pomerantz
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-2250 2-channel amplifier deploys 175 watts RMS to each channel, giving your music plenty of firepower. Or you can bridge the M-2250 to mobilize 500 watts RMS to your sub. An adjustable high-pass filter makes sure your full-range speakers operate within their optimum range and give you the best tone possible. If you're driving a sub, the variable bass boost and low-pass filter allow you to control your bass barrage at will.
The M-2250 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 crank up your system.
Although this amplifier has a port for a remote control built in, it's not functional, and a remote controller for this amp is not available.
Excellent power bridged pushing a Kicker 12" Comp S....Only 4 stars because the adjustment screws are sort of a pain to get to..

I installed this amp in the rear compartment of an 84 Ford ambulance I converted to a utility vehicle. It powers a pair of JBL MR925 cabinets. It sounds fantastic!! Coupled with the cab and intermediate speakers that are also powered by a Sound Ordnance amp and the whole system is incredible!! [ DANIEL Oct 23, 2016 ]
When I asked Levi to recommend power and subs on a 16 year old budget, he pointed me directly here. Based on my history with Crutchfield, I doubt him not a bit. Levi's Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=67 [ THOMAS Aug 16, 2016 ]

Yes both the Low pf and the High pf can be adjusted. Hope this helps [ JOEY Mar 06, 2017 ]
1 answer My amp had been working fine and then stopped completely. Unit powers on with head unit, but Protection light is on and no sound comes from the speakers. The manual says that the Protection light indicates a short in the speaker connection, but even with both speakers disconnected the light stays on. What could be causing this and how do I fix it? [ Shane Jan 22, 2017 ]

I do not use a remote with this amp. I do not believe one is available. Overall the amp is great at what it does. [ walker Oct 06, 2016 ]
Yes you can, If I remember correctly my amp came with a remote. Contact Crutchfield directly to confirm. [ BRAD Oct 06, 2016 ]
I want to say it accepts balanced inputs, it's been a couple years since I've used this amp so I don't recall. I do remember this being a decent amp to use if you have the right subs [ Nathan Aug 22, 2016 ]
This amp puts out 175 watts RMS x 2 at 4-ohms which would match up nicely with your 150 watts RMS Kicker speakers. Generally you want your amp to produce between 75-125% of your speakers RMS power rating; so if your speakers are rated for 150 watts RMS, an amp rated between 110-190 watts RMS per channel would be an ideal match. I hope that helps. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=159 [ Larry Mar 11, 2016 ] Staff
Lights should be off when car is off. The remote lead wire should be tied to an inviting power source so amp is signaled to turn on only when ignition is on. Sounds like your remote power wore is tied to a battery line (constant power). Yea it will kill your battery. [ MICHAEL Dec 18, 2015 ]
The light was only on when the power was switched on for the unit we installed. Check to be sure that the switching wire from the stereo, blue I think, does not have any current in it when the car and sound system is off. Not sure about the protected light, but no lights were on when off. We will be getting this car back in this winter and if needed I could check that light for you then. If the amp is actually powered on when the car is off, it will drain the battery. [ WILLIAM S Dec 18, 2015 ]
The power light should only be on when your stereo is on, assuming you've correctly hooked up the remote power cord. If you wired it without the remote line, you'll need to manually power the unit on and off, and yes, it is draining your battery while that light is on. [ Ryan Dec 18, 2015 ]
For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Krissy Dec 14, 2015 ] Staff
