Sony's Xplod amps combine form and function in a mix that'll make your system look and sound great. On the outside, the sleek inverted heat sink keeps vital internal components running cooler and lasting longer. Removable terminal covers keep all the wire connections protected and out of sight for a clean-looking installation.

Underneath the hood, the 2-channel XM-1252GTR delivers 125 watts to two channels, or 340 watts in single-channel operation — plenty of power for many subwoofer systems. Signal-sensing speaker-level inputs activate the amp automatically when you turn on your factory radio, so there's no remote turn-on lead for you to install.

Built-in frequency filters tailor the sound to fit the application, while a bass boost adds extra punch to the lows.

Product Highlights:

  • 2-channel car amplifier
  • 125 watts RMS x 2 at 4 ohms (170 watts RMS x 2 at 2 ohms)

  • MOSFET outputs and power supply
  • Tri-way capable (Tri-Way crossover required)
  • CEA-2006 compliant
  • speaker-level inputs with signal sensing for automatic turn-on
  • preamp inputs
  • fuse rating: 30A x 2
  • 4-gauge power and ground leads recommended — wiring and hardware not included with amplifier

  • warranty: 1 year
  • 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.

Inputs and Outputs Notes


Protection Circuitry: The Sony XM-1252GTR amplifier has 3-way protection circuitry, which protects the amplifier in the following cases:

  • Thermal: shuts off the amp when the operating temperature is too high
  • Short circuit: shuts off the amp when the speaker outputs are short-circuited
  • DC Offset: shuts off the amp when the speaker wires or ground lead is not securely connected, generating direct current

Protector LED: The amplifier has an LED on the top panel that glows red when the protection circuit is activated.

Internal Filter: The built-in filter can be set for low-pass, high-pass, or full-range operation. The filter is fixed at 80Hz with a slope of 12dB/octave.

Inputs and Outputs Notes

Power/Ground Terminals: The power and ground screw terminals are 0.54" wide to easily accommodate 4-gauge wire.

Speaker-level Input Harness: The amp comes with a 2-channel speaker-level input harness with a 4-pin Molex plug on one end. This allows you to more easily connect this amplifier to a factory deck or a receiver without preamp outputs.

Bridging the Amplifier: When bridging the amplifier, the line input jack and speaker output terminals labeled "BTL" are used. The input signal is plugged into the left channel input and the output signal comes from the left positive and right negative speaker terminals.


RMS Power Output (supply voltage at 14.4 Volts):

  • 125 watts x 2 into 4 ohms (20Hz to 20kHz, 0.1% THD)
  • 170 watts x 2 into 2 ohms (20Hz to 20kHz, 0.15% THD)
  • 340 watts bridged into 4 ohms (20 Hz to 20kHz, 0.15% THD) 

Maximum Power Output:

  • 280 watts x 2 into 4 ohms
  • 400 watts x 2 into 2 ohms
  • 800 watts bridged into 4 ohms

Current Drain: at rated output: 32A (at 4 ohms)

Great Punch, Great Price!!!

Written By DOrtiz357, Chicago, IL on Monday, December 22, 2008

I bought this to replace a cheap amp i was using to power my Pioneer TS-W252R 10" Subwoofer. The power supplied by this Sony amp was way too much for that sub. I returned the sub and bought a Pioneer TSW257D4 10". NICE!!!!!!!! Its powers it up nicely and sounds so GREAT!

Crutchfield Customer Review (What's this?)

My only beef is that the HP/LP filter is not variable (set at 80 hz). Would be nice if the low boost was variable as well (40 hz), but I don't know if anyone offers that. As far as getting what I expected, I got absolutely that and I would give it a five, but it gets a four simply because nobody should leave out a variable crossover for a HP/LP filter. After remembering that my Sony CDX GT-310 had a LPF at 125 hz, I used that instead and left the filter on the amp off. Sounds great now! Overall I recommend the act.

Perfect for the price

Written By Angelica, Marina, CA on Saturday, August 04, 2007

I bought this amp from the Crutchfield Outlet for my boyfriend. He was looking to replace a lower-powered amp that he was using to power a 12" Sony Xplod subwoofer. As soon as we hooked it up in his car and turned it on, we were really impressed with how powerful the sound was. We bridged the amp to power this single speaker and it works great. There are a couple things you should know before buying this. The gain and the bass boost have to be adjusted with a screw driver, which can make it a hassle to make changes. Also, the amp gets hot enough to grill a steak. However, I've run the amp for hours and had no problems with it shutting off. One thing I didn't really like about this amp was that the low pass filter seems to cut the frequency too low, leaving a gap in the sound. I just leave it on all pass when running the sub. This amp is a great deal, it serves my purposes with power and it's going to be a long time before I even think of changing this one.

works for me

Crutchfield Customer Review (What's this?)

I purchaced this amplifier to power two 8" Rockford Fosgate subs in custom made ported boxes. The main reason I purchaced this amp, other than I just like Sony, is because it has line-in sensing meaning that I don't have to run a remote wire. This was especially important because I left my stock Bose stereo in place and didn't want to have to "tap" into existing wires to run a remote. Everyting about this amp has exceeded my expectations, meaning that the power is more than adequate, sound is great, line-in sensing works flawlessly, and the connections are easy to use and understand.

Just watch out that you don't over-tighten or loosten your connection screws; they cross thread and strip pretty easially.

I connected into the rear speaker wires in the front passenger-side door sill, and ran my power wire through the firewall through the large rubber gromet above the left foot area on the drivers side. The amp is located on the center hump under the rear seat, and it's low profile does not hinder midgate operation.

Very Nice

I had two of there bad boys pushing two Sony 12" subs. Yea, a lot of power. Well I was very impressed with this setup. After a couple of times of ajusting the settings, it was the bees knees. I was told by a friend of mine that he could hear me from a little less then a mile away. I went to 2 car audio competitions and won both of them with this system, and there were over 10 competitors in my class. So i guess what im trying to say is if you want competiton quality, get the same set up i had.

Hi..First off i would like to say that this is a great amp....I am pushing Two 12" Kicker CVR's (the good kickers.) this 800 watt Amp Is CEA its really 800 watts....alot of other amps are not CEA compliant....and they claim to have a certain amount of maybe 600 for a example....but if its not CEA may be geting half of the wattage or less....alot of companies like to put outrageous watt ratings and they dont follow through....but make sure you do your homework....anyway another good thing about this amp is when i'm done listening to music I expected the amp to be very very hot....(It wasnt) it was just alil warm....some amps get so hot you could cook a egg on them....(which is not good) now...what im about to say doesnt really matter in performance...but if you are about some looks like myself....this amp also has has a see through circle on it where you can see the insides of the amp....kinda neat :) and it also glows a pretty blue that lights up your went good with my setup because i have blue underlights on my car anyway :)anyway if you all are looking for a great amp (for a wonderfull price) then dont over look this amp....its really good :)

Good amp for price

Written By David, La Grange, Kentucky on Tuesday, July 25, 2006

Really powerful amp for the price. I have it running 1 10" sony sub and 2 6.5" pioneer door speakers, using a tri-way crossover and its loud. I recomend this amp if your on a budget.

Very pleased

Written By Rhonda, Cleveland, Ohio on Friday, May 05, 2006

Newer sleek design from Sony. Provides enough power to sound loud and great, especially for only $150. 10 dB 40 Hz boost is very nice.

Buy this!

Written By ryan, Saginaw, MI on Thursday, March 30, 2006

Buy this! If your wondering whether it's worth it, it certainly is. I just bought one of these the other day for my two 150 rms dvc hed-10's and they punch out some deep bass. Other drivers just stare... Get's the real bump out of my subs... rocks my small 96 corsica. Get this amp!!!
