ORION XTR750.4 XTR High Power Class A/B 4-Channel Amp, 750W RMS

Took a while for tolerable temperatures 2 run this fantastic piece of engineering in the ride but worth the wait after initial testing. It runs my 4 components beautifully! Never getting rid of it! Still waiting for my monoblock and eventually my 2 batteries to replace my temporary battery but the fact that I can get by happily with the components ran off the first two channels and temporarily run my sub @4ohms bridged keeps the smile on my face till I can complete my project. Great great piece of engineering. (Updated Commentary) Has handled two winters with ease. Had originally ran the1st 2 channels for the front n rear components and the single 10 until I got a monoblock. After monoblock was purchased I got 2 run my components on each channel finally. After testing what worked best (high pass or full range) I figured out what I was satisfied with. Utilizing the dsp on the head unit I will not settle for any other 4 channel. I cannot wait to order 2ohm 6.5" with 1" tweeter components that carry 2ohm load for the fronts & rears now that I have finished upgrading the subs. This amp is a beast even if you part it out for half highs/mids and other half bass. Just make sure you utilize the high & mids down as low as 2ohms (in my case average of 208watts @13.6volts) and mono 4 ohms bridged (750 watts rms).

I've dealt with Orion before and they are AWESOME amps for any system bog or small but they require a significant amount of power. This is not necessarily a bad thing just something to keep in mind. You'll get the dimming lights when the bass hits but that's easily fixed by adding a capacitor.

Using to push a couple 12 woofers in my Chevelle and it's a clean Amp. NO hissing that I can hear.

The sound quality and volume of this small amp is awesome I can’t speak for durability but it’s a heavily little fella and will be buying the same brand for my other needs

Amplifier purchased and on installation went into protect mode. Found it strange as previous XTR functioned normal. Got my refund, but no support from Orion

*item update* After a few years of use, I have had two issues. One with the small board, and the other with a power bus bar on the main board. I was able to re-solder the bus bar. So after that was resolved, I have had no other issues. Still works great! Orion is always my first choice in car audio. I have the XTR2500.1Dz and it performs very well. For some reason the title says this one is a 600.4. The one you will actually get is the 750.4. *edit* After using this amp for a long while, I have had trouble with it twice. The small board that goes to the adjustment pots on the input side has came loose. You have to remove the bottom cover and reseat it. I think I'll try some silicone to adhere it to the connection point inside.

Love the amp Gets hot tho', in about an hour and 20min But in FULL BLAST Powering: 2 Soundqubed TH-25 super tweeters 2 Soundqubed MR6.5 midrange SOUNDS AMAZING Friends can hear me about 2 blocks away 🔊💯🔊

Awesome amp! I installed it for my mids and tweeters. Way under rated. Great sound quality. Its hard to wrong with orion xtr amps.

Very good product
