Orion XTR Series XTR500.4 High Power Class A/B 4-Channel Amplifier - 500W RMS, 2/4 Ohm Stable, High/Low Pass Crossover, Bass Boost Control, MOSFET Power Supply, Bass Knob Included, Made in Korea

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).

bought this am about 3 months ago and its worth it.. but it was out of stock . so he sent me a xtr2500 amp instead!! woot woot!! (2500.1d) 1050 at 4 ohms-1600 at 2 ohm and 2500 at 1 ohm, all at 12.5 volts! nice man very nice!! i guess i caught him at the right time ot get one. i cant find that model number anywhere on the net but i have one!! its not the old one it is the xtr like the one shown. he said it was a newer model. its not on orions website also. ( its never updated anyhow) i have some xtr pro subs from orion and you only see the regular xtr now. not the pro. but anyhow. its a nice amp. buy it.sound is good and clean . the bass nob is NOT a bass knob, its a remote gain control.even better!adjustable phase for subs not a 0-180 switchbass boost works like it should..i like that its rated at 12.5 volt and it comes with a birth sheet . mine is under the specs on the box but trust me . when u have 1550 watts at 12 volts as opposed to at 14.4, at 2 ohms. you arent complaining . most amps barely do rated at 14.4 much less being real wattage..end result is i like it .. id buy it again if i needed too.

I love a good deal. My Rockford Fosgate 1500 BD stopped working. I decided to buy a new amp vs repairing. I came across a Dyno test Video for this amp done by YOUTUBE USER "BigDWiz". I was sold... The amp arrived and I installed using the same 4 gauge(Stinger OFC) as I used with my Rockford Fosgate 1500BD..... BIG MISTAKE, the 4 gauge wire was not receiving or dispersing the power efficiently. Amp would get HOT enough to Fry Bacon and Eggs on...needless to say, I ordered a pair of dual 1/0 gauge input block terminals to install on amp for power and ground. Once THIS BABY had all the juice it needed.....Pounds relentlessly for Hours and no longer gets warm at all. This ORION XTR2500.1Dz is everything I needed!! I have four 12" MTX fpr shallow mount subs in a custom down-fire box wired down to 2ohms in a 2015 F150 SuperCrew. This amp is giving them about 2200 rms @ 2ohms. I have the amp gain set to 1/4. PLENTY OF QUALITY POWER!! aWESOME DEAL HERE!!My Electrical* 250amp Alternator(Stock for F150(V8)* XS POWER D3400 Under Hood and XS POWER D680 in rear* 1/0 BIG THREE UPGRADE and ADDITIONAL 1/0 gauge Ground from front Battery to vehicle body* 1/0 Stinger OFC wire throughout

I had no problems installing to my custom box. It is powering 3 12" Kicker L7's at 1.39 ohms. I already had 1/0 ofc power wire with 2 battery's in a 2007 suburban. To date this is the loudest system I have ever had. Every person that I had sit in the vehicle could not believe how load it was. So a really great amp. The con is going to be the remote bass knob. This knob is very cheap. Mine was completely destroyed with the knob coming out of the housing. The bass knob was replaced by seller through amazon and received it very promptly. The knob I received was this one https://www.amazon.com/gp/product/B07J2QXBB2/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1I have verified that it will work with the original wire or the wire that comes with the aftermarket knob. I am getting some feed back from the amp to the subwoofers while the volume is completely turned down. It seems to only be noticeable when driving so will need to narrow it down. The amp before this was a 1500 watt Kicker and had zero bass noise when volume off. If your going to use a bass knob buy one while your ordering this amp. would definetaly purchase this amp again.

This is an excellent and well-made amp. I bought this amp to replace an old Orion HCCA-D2400 and I couldn't be happier. This amp is more powerful and more controlled than the old HCCA was. Bass now seems punchy and tighter, less boomy. It is driving a single American Bass XFL 10 D2 @ 1 ohm. I can now hear the bass much better at my normal low volumes, so it seems the power is more linear. This amp is more powerful yet smaller than the old HCCA which I was very happy with.For me the negatives are minor. The plastic end caps must be removed to effectively get to the set screws for wire connections as well as the mounting tabs, but in my case, due to the way my amp is mounted, I could not put them back on after mounting the amp. This amp does not have as much fine tuning as the old HCCA did, such as the subsonic filter, it is either off or on @25 Hz. There are three lights on the top of this amp including power, protection, and thermal protection, however as nice as that is, the lights are not labeled and must be memorized in order to diagnose without the manual handy.

I bought one of these early 2021. Never had an issue until now. But it was all my fault when installing in my new vehicle lol. So I’ll be buying another cuz this thing bangs my single Q-Class L7 15” in a Super Bass ProBox 4.5 cu ft. Never even got warm and I blast at max all day. Ten Stars
